I spent all winter hoarding performance goodies for the Terc. I finally had one free day and awsome weather so I decided to start modding -sly-
I took lots of pics so here's a DIY Qball style...![]()
---------------------------------------------------------------------------------------------------------------------------------------------
Before you start. Put the transmission in 1st gear if it's Manual. Make sure it's in "park" if it's an automatic. I had my
Terc on 4 jackstands so I did none of that.
Jack up the back of the car using the factory lift points on the rocker panels and then place jack-stands under the rear axle. Now remove the
wheel.
Let's get down to business.
This is the little nasty rusty drum brake setup Toyota equiped our Tercels with. Although completly adequate for the weight of the vehicle, it just
looks plain fugly when you've got some sweet alloys on your ride.

Start by removing the dust cover using a flat-head screwdriver/chisel and a hammer. Tap the cap alternating sides to pop it off.

Now you'll see the cotterpin and nut retainer. Remove the pin using a set of needle-nose pliers to straighten the pin legs and then pull it out.
The nut retainer should come right off after the pin has been removed.


Now remove the nut with a 22mm socket. Both sides of the car use regular thread. No reverse threads here. So "righty-tighty, lefty-loosy"
applies here too.:D

Remove the washer.

The bearing should now come out easily.

After the bearing has been removed the drum should come off. There may be some hesitation. If you need better leverage, try putting the wheel back on
with a couple of lugnuts and use it for leverage. There is also an adjuster inside the drum brake assembly that can be accessed through a hole in the
backing plate which is plugged with a rubber grommet. Release the shoes like that if you just can't get the drum off otherwise. Older drums
usually have lips worn into the drum which makes them harder to remove.

This is what you should be looking at after removing the drum.

Remove the giant retractor spring by prying it off with a screwdriver or do like I did and use your hands. It's really not all that stiff.
It's function is to retract the brake shoes when you let off the brake pedal.


Next you need to remove the retaining pins. These hold the brake shoes in place. There's one in each shoe. Reach around back with one hand and
hold the pin in place. Then with the other hand, push the front washer in and twist to release the washer. Now remove the pin, spring and both
washers.

You should be able to remove the shoes one at a time.

Remember not to lose the bottom spring that connects the two shoes.

Now remove the e-brake cable. Just pull the spring back with your hand and slip the cable out of the bracket.

Release the e-brake cable from the backing plate by removing the two little bolts with a 10mm socket.


Now it's time to get under the car and unbolt the solid brake line from the axle. A standard open-end wrench will most likely strip the nut so
use a linewrench. This is a special wrench that has more contact surface than an open ended wrench which will protect the nut and allow you to loosen
even the most stubborn nut. It's like a box-ended wrench with a slot in it to slip over the pipe.


Now unbolt the backing plate from the axle by removing the 4 bolts with a 14mm socket.



It's now time to prep the Starlet GT disc rotors. I know it's really rusty but I love it :D

Remove the old inner bearing seal with this wicked seal puller.

That seal puller looks like a weapon you say? Well I'd have to agree:mad:

After pulling the old seal. The bearing comes right out.

Let's hit the parts washer for some cleanup. You can tell I love this part....mmm....solvent -lol-

Clean the bearing out well and then blow it out with compressed air. You want to get ALL the old grease out.

Do the same for the rotor.

So fresh and so clean-lean-lean...sorry....anyways - back at the ranch...


Repack the bearings with wheel bearing grease. I do it manually but you can use a bearing packer. You can use either the Tercel or Starlet bearings.
But I prefer to use the Starlet bearings since the race is installed in the rotor already. Make sure to put some grease in the cavity of the rotor too
to make sure the bearings will always have grease.

Now it's time to re-install a new Genuine Toyota Japanese built inner bearing seal. Again the USDM/CDM 91-99 Tercel seals fit the Starlet GT
rotors.


I didn't get a pic of the seal driver I used so here's what it looks like on top of the old drums. Use it to pound the new seal in nice and
straight. Apply some wheel grease to inside of the seal to protect it later during sintallation.

Now that the rotors are preped it's time to go back to the axle. Clean off the flat mating surface with a wire brush and sand paper. Then cover
it with anti-cease just in case you ever need to remove it in the future.

Bolt on the new backing plate with the longer bolts from the starlet GT setup. The Tercel bolts are too short.

Coat the spindel with some more axle/wheel grease to protect the seal during installation.

Slide the rotor onto the spindel and re-install the newly re-packed outter bearing, washer, nut, nut retainer, cotter pin, and dust cap. All those
parts can be used from either your Tercel or the Starlet. They are all interchangable.

Bolt the caliper bracket to the backing plate. 12mm wrench. Now's also a good time to clean the rotors off with some aerosol brake cleaner to get
all the grease and solvent off before installing new pads.


Open up one of your boxes of brand new Genuine Toyota pads. -sly-

Install the pad shims. Again..rusty I know.-love-

Use some anti-squeek and apply it to the contact patch of the shims.



Time to prep the caliper. I had already rebuilt these but I had a couple of pieces left. Copper washers for the flexible brake hose.


Make sure to retract and rotate the piston into this position before bolting the caliper to the bracket. The little bumps/tabs on the brake pads have
to fit into that slot in the piston to keep it from rotating. So make sure it's installed properly.

Now snap the other end of the hose in place on the bracket with the C-pin.

Attach the hard line from the Starlet setup. The Tercel line doesn't fit. You may be able to bend it to fit but if you have the Starlet lines,
use them. IF you don't want to wreck your Tercel setup, then go out and buy some hard lines with connectors and bend it to suit your needs. They
cost less than $10 each.

that's sexy.

Ok when you're done admiring your own work it's time to get messy again. Time to hook up the Starlet GT e-brake cables. I won't sugar
coat it. This part suxorz.-blah-
You have to remove the aluminum exhaust heat shield to get at the e-brake cables.


You're gonna have to make some room to work in there so unhook the rear muffler hanger and slide the whole exhaust off to either side.

Then using a large drilbit to drill out the 3 aluminum rivets that hold the shield in place. Don't worry. You can re-install it later.

Now get in the car and take your 10mm socket, extenssion and ratchet with you. Loosen the adjustor nut as far as you can without backing it off the
bolt all together.

Get back under the car and remove the cables with a 10mm socket.


Now you'll run into a problem. At least I did on my 98 Tercel.
Starlet cable on the left - Tercel cable on the right.

I had to fab up some sleeves out of a piece of 10mm conduit to solve the problem.

MINT!!!!

Unfortunatly the Starlet is a little shorter than a Tercel so it's cables too are a little shorter than the Tercel's. So you can only use
one mounting point on each side.



Route the cable through the stock location on the axle. You will have to remove the grommet and then pass the cable through the hole. Reinstall the
grommet over the cable and squeeze it back into the hole.

I didn't get any pins to attach the cables to the rear calipers so I had to make some. I used some TOYOTA bolts that I had lying around. I cut
them to length and drilled them for a cotter pin.

Now that you're done with the cables you can re-install the heat shields using some standard aluminum pop-rivets.

Go back into the cab and tighten that e-brake tentioner nut.

That's it. You're done. Now just bleed the brakes and top off the brake fluid. Put the wheels back on and you're ready for a test run.
BTW this setup will fit with 13" stock wheels.
Good luck guys -ccolguy-

this is a great diy-shock-
sticky!!!!
-dumass-
nice job -coolguy-
oh , almost forgot to ask how was your test drive ?how noticalbe was the difference in braking power?
| Quote: |
I want pictures of the sexiness with everything put back on.
qball remember that the pads have a breakin period of a couple of hundred miles during which you shouldnt get them white hot :)
Dang dude you got lucky like 4 times with that customize stuff you do....and that stuff you have laying around..im jealious lol
nice setup dude
Wow, you made it look so easy. Awesome DIY QBall.
Damn, I just had my rear brakes machined last October. Guess I will just have to drive with the e-brake on for a while to speed up the wearing out so
I can replace them.-banana- I was rear disc brakes now.
VERY nice writeup, I just have a couple questions.
1. Is there no need for the starlet rear axle? You can put it on the stock tercel axle? That wouls save a bunch of money and time...
2. Why did you switch the ebrake cables? Why won't the tercel ones work? Instead of fabbing up something to make the starlet cables work,
couldn't you shave the other end of the tercel one or modify it to fit the starlet calipers?
Once again, great writeup. I just want to clarify a couple things before I start acquiring parts.

Pretty much all the tools are my pop's. He's a lifelong mechanic/machinist so he's got pretty much every tool you'd ever want. except a welder cause you can't weld indoors in the winter -lol- no garage -lol- wait... -irked-
nice DIY!! -banana-
rims with rear discs -boring--boring--boring--boring--boring--boring--boring--boring--boring--boring--boring--boring-
Dude. That was one of the hardest mods every. I honestly changed my brake line like 3 times. the 91-94 at least was a total
. anyway it was very helpful tho. just make sure to pack the bearings w/
axle grease like put the bearing in your hand and whipe with it. DO IT ALOT! because it needs it. After like 8 hours of putting the brakes on im
finally finished but i did have a problem the bleeder was busted when i got it so i had to replace it with the one from the drum which fit fine. By
the way qball how did you get the caliper on with the metal pieces on the pads??? Any way it was a great DIY pictureized thread and someone should
deff sticky this. but when you print it out its gunna be 75 pages. lol haha Ill get pics up tomorrow........im tired as
.
Later
John
By the way the starlet axle is no shorter then the tercel axle. I was going to replace it with my axle in the rear but they both are 51 1/2 in a
piece. Thought that was interesting since it came from japan?? Maybe didnt come from a starlet? Anyway qball my starlet rear axle didnt come with
the rear bearings. the fronts it came with but I duno what happened to the rear ones. YOU NEED TO MAKE SURE THAT THE RACE INSIDE THE ROTOR/DRUM FITS
THE EXACT BEARING IT WAS PUT WITH. If you don't that will be a bad thing. haha actually they wear down with the bearing. But i bought new
bearings so it wasnt a problem.....still havent done the ebrake tho. darn. have to order some new cables since i sold them to qball. glad they
worked out. I might just cut my ends off and fab somtin.

looks sweet! -coolguy-
interesting white wall choice there lol
that looks so very nice. specially the red painted brakes
-lol- -they're not whitewalls man. It's the polished aluminum lip of the rim.
- If you don't replace the race with the bearing it belongs to, that means you have to constantly take off your wheels and readjust the bearing
tention with that nut as the bearing wears into the race or visa versa. That's why it's better to use the race that came with it. BTW I was
gonna buy new bearings but these sets were both fine.
- repacking a bearing manually takes a long time but it's completly necessary. You can use a bearing-packer attachment for your greasegun but
that wastes a lot of grease. Whatever you do do not just slap on a little bit of grease and use install the bearing. Make sure you pack it so the
grease oozes out of every opening.
oh yeah...thanks for the compliments and special thanks for the cables 94 -sly-
Someone put on their wheels and tires -banana-
Well, this is my disc brake conversion. Mine werent that screwed up so it wasnt a big deal. 

I can get more pics im just lazy. I will do a DIY on how to do the ebrake cables on your original ones. and lots of pics will be available. But if
you want more pics ill have to jack the car up and take the wheel off. Enjoy!
P.S. qball your welcome -sly-
Wow, no one commented on the car.........i feel bad for myself. lol
BUMP this is a great thread lets see who else has rear discs?
John
Qball and 94Tercel...Great job to the both of you!
VERY impressive!
Defintely worth a sticky!-coolguy--coolguy--coolguy-
[Edited on 12-4-2005 by Tercman 91]
QBALL: Is it necessary to remove the shoes and internals of the drums? Or can you just unbolt the 4 holding olt and take everything off as an assembly?
Everything has to come out before hand because the shoes sit overtop the ebrake which makes it so you cant unbolt it. Kinda a pain but the
disassembly is the least of your problems.
John

Test drive yet?
Qball, could you list the tools that you used?
(I like to stockpile the tools I could use someday, but they pry will sit in the toolbox -banana-)
| Quote: |
Here's something for somebody to check, does the rotor have the wheel mount in the same location as the drum? It may be the rotors that create
the narrower width.
-eureka-

well here's an update. I've definately got that test drive in now. And I've put about 4,000 km on the brakes and they are only now starting to wear in
-haha-
I make it a point to use the e-brake and pedal whenever I do a hard stop or when I'm just cruising and coming too close to the traffic infront of me I
use the e-brake to slow down a bit.
All in all the braking is pretty good although most of the noticable difference came from the Paseo front brake upgrade.
I think it would be a good idea to upgrade to a Starlet GT perportioning valve to transfere a little more braking pressure to the rear.
Hey guys that was a great job!!! QB the DIY was awesome! Ok, now to what i need.. since im in Iraq and on a government computer the pics to tthe DIY
wont come up on the screen, this happens to me on every page!! Id appereciate it if someone took 3 minutes of their time and emailed me that DIY with
the pics... thanx alot!!!
My email : gonzalez.ramos@us.army.mil
can you right-click on them and save as?
the images zipped up are 7.12MB BTW
iVE TRIED EVERYTHING QB BUT IT JUST WONT WORK OUT, THE ONLY WAY IS FOR SOMEONE TO EMAIL THEM, I WOULD APPRECIATE IT VERY MUCH. THIS INTERNET SYSTEM BELONGS TO THE ARMY AND THEY BLOCK EVERYTHING, EVEN YAHOO, AND HOTMAIL, AND ALL THE PICS THAT DONT BELONG TO THE ARMY WEBSITES JUST WONT APPEAR ON THE SCREEN.-1zhelp--1zhelp--1zhelp-
" gonzalez.ramos@us.army.mil" Is this address correct or is it suppost to be "@us.army.mail"
nah QB, its us.army.mil thats the right one, thanx-dunce-

US army mail server stripped any .zip attachments so I changed the
file extenssion to .bmp. Once you get it. Change the extenssion to . zip again and you'll be able to open it and extract all the jpg image files.
Hey QB, i got the pics, thanks alot man, this is really gonna help me out alot when i get back home and coninue what I started on my baby, ill be posting some pics up soon..-say-
For the 91 - 94 Tercel owners who did the rear disc conversion a few questions,
- Did you run into alot of the problems that Q ball did?
- Where did you get your Starlet discs from or what was the equivelent used?
- How long did it take?
Good looking out in advance.
UTA
post the pictures of your work 94 tercel
now looking at this I realized something
When I installed my cables i had to do the opposite mod. I had to drill the plate to make the holes larger so that the cable thingies could fit.
I guess my cables were from an ep91 which would have fit your 95+ terc without any mods. And your cables would fit my terc without any mods. oh
well... not a big deal but I thought I'd mention for the future generations.

To do this on a 92. Is it the same thing. Sorry if you all answered this already.
The rear bearings on the rotors from the Starlet and all year Paseo's and Tercel's are the same from what I have read. The front should be almost the same don't know for sure as I have never replaced the front bearings.
Hi new to the Tercel ranks with my 90 tercel Carb/auto has any thought of maybe trying to put together the complete kit of the rear disc conversion
since it seems to fit so many years of tercels and the like. Maybe even having some convert the tips of the brake cables so the tercel style brake
cables can be used so there no drilling or real adaptin
Just make it an entire package and make it a giant group buy or something.
Is the any issue with proportioing valve and master cylinder going from front disc/ drum setup to all discs?
By the way may I ask this is for US style cars? For some reason I do not remember the little starlet coming with 4 wheels disc brakes here in states.
I even sold toyota's in 87-90. Pardon my noobiness
[Edited on 21-2-2007 by Ranger4219]
This sounds like fun, I've don Rear Disc conversions before and this looks like Standart stuff, I'm just wondering where you get the parts for this conversion? Can you buy them new or Reman from an auto parts supplier or do you have to wait for one to show up in the salvage yard? If someone can point me in the right direction, I'd appreciate it, my contacts for Toyota parts are lacking.

Wish to do same conversion on my 90 EL31 Tercel cpe I noticed there are two chassis numbers on your conversion. Are they both the same for conversion Starlet GT EP82 / EP91 rear disc brake conversion for Tercel/Paseo or should i look for a chassis specific version for my 90?
I am ignorant a bit here so please bear with me...
Does a tercel...when you break normally with the foot break...break on the back and front breaks or just the front and when you use the E-break just
the back? I was always under the impression that only the front wheels break when you use the pedal...
Like I said...ignorant...
No sir ,you use 80% braking in front and 20% in back. When you use the ebake it is just the back.
| Quote: |
i think you will find it is a little more than 20% at the back
The other day my e-brake cable snapped. Since the lever was completely loose I assumed it was the short front cable that tore. After throwing it on
the hoist at my dad's shop a week later (Thanksgiving day) we found out it was the driver's side rear cable that snapped inside the sleeve. It was
totally rusted.
My dad happened to have my old cables from the drums. We modified the back end of the cable using the starlet sleeve stop and the little eyelet that
connects to the caliper. We cut the drum brake cable to length and brazed the eyelet on.
Works great now. That's the downside to using 16 year old Starlet cables.
| Quote: |
what did those run ya'?
| Quote: |
I will say this though. The benefit of modding the original Tercel cables instead of using starlet cables is that the cables actually fit into the factory clamping locations. The Starlet cables are a few inches too short for a Tercel so one has to string them as the crow flies.
i was wondering...might any of you know of any site where i can order online the backing plate for the disc brakes?
can you help me to find the complete kit, I want to do the same conversion but i cant find the parts
HELP!!!! 
| Quote: |
in the works right now.
the plan is to eventually have/keep those in stock at all times. 
keep an eye on the T-Bay thread for updates.![]()
and when is that gonna happen?, cuz right now Im thinking to adapt some of a se-r 
| Quote: |



Reason being, the passenger side cable was actually tigher and did not fully
release even when hand brake was down. No bracket to support the brake lines by the wheels like these and a hard line?

[Edited on 14-6-2009 by Tercel GTS]
I have SS Braided lines with my kit. It's just one long line per side. No harndline or rubber line, therefore, not using the bracket. However, the
problem is the banjo fitting and the bolt that locks down the banjo end to the caliper. I couln't even get the caliper mounted to the bracket, that is
how badly in teh way it was. That's been taken care of.
What I'm really trying to focus on is the e-brake cable--if they are specific to each side--driver/passenger. I think what I'll do is take it off and
lube down in the lines.
Yeah?
I was able to use all the mounting points, but I had to move one on each cable.
So the cables are different.
This is teh tercel cables, but I think it applies to the starlets as well and I think I prolly mixed them.


About 1" length difference.
Also notice the Tercel cable is tagged with colored tape--one green the other yellow.
I bolted back up the heat shield that protects the cables from the heat in the exhaust track once I attatched the ends so I never got to see what it
loocks like in the junction where the two cables meet with the singel cable coming off the e-brake lever. I'm thinking that it is probably badly
tilted since the one that is supposed to be longer is actually a bit shorter and that one thats supposed to be short is a bit longer.
BTW - I still have a spare set of Starlet rotors if anyone wants them. I clearly have no need for them anymore...and could use the gas money.
