    Rear Disk Brake Conversion

    Anyone ever do a rear disk brake conversion on an 8-gen Rolla?

    The parts for a AE101 are supposed to bolt right in (if you can find them).

    I bought the complete kit from Shyguy. He had a showcar corolla in Canada. I don't know where he sourced it from.

    If I were you, I'd go with Dr Tweak's conversion kit. It uses '95 Celica GT rear rotors. All you'd so is buy the $30 dollar rotors and have them redrilled for 4x100 at a machine shop. If you get em from the ae101/111s you'd end up like me, I have to buy replacement rotors @ $200 w/o shipping.

    You might want to get your brake pressure valve replaced since you wouldnt be applying the optimal brake pressure since drums require less pressure to work optimally compared to discs. Most people don't do this tho but I am planning to.

    I haven't checked this board in months... Sorry to bring back an old thread, but does Dr. Tweak still offer this kit?

    But it's RWD. The setup is different. The donor has to be rear disc FWD.

    I thought of a way to make a super cheap rear disc conversion. you need a 1/2" steel plate to build a caliper mounting plate. then you can use corolla front disc calipers & rotors and you're set. $250 rear disc conversion and uses all stock equipment

    That's the only possible direct bolt on donor. The AE92 GTS.

    I'll be looking at it too. The question that comes up is that the on a FWD car, the drivetrain is in the front and powers the front wheels. Whereas the rear is just trailing. You will have components from the front that won't work with the rear. It could be possible though.

    I'm interested. Let me know how it turns out.

    well I haven't taken measurements but this is a general shape of what the plate would look like. mounts behind the axle hub meaning:

    you need to use the front brake dust cover, need to use longer bolts, need to use torqued nuts to hold the plate on.

    ooh.. autocad. I love that program.. I still need to learn solid works because that is the industry standard for MEs.

    Anyways I say AE92GTS rear setup will work best. It'll bolt right up to the strut and and trailing arm. The problem is in the rear control arms. The AE92 have the bushings built on the hub/knuckle assemble while the AE101/ZZE111 have them on the control arm assemblies.

    However that obstacle can be easily solve by frankensteining the outer AE92 control arms half + the AE101/ZZE111 inner halfs. Notice 2 out of 4 control arms have a threaded turn buckle in the middle for toe adjustment. all you have to do is unscrew the stock outer half's and screw on the AE92 outer half's.

    But you do need to grab 2 more AE101/ZZE111 and AE92 adjustable control arms. This process is all bolt on with no machining what-so-ever.. I think it'll be a good weekend project.

    Because the the hubs are 5 lug instead of 4. If you don't mind having 4 lug in the front and 5 lug in the back, go for it. LOL :D You can always swap the hubs for 4 lug ones, but that involves more unnecessary money.

    He was referring to the 9th generation Corolla, which had a 5 x 100 bolt pattern.

    the idea of use ae92 components seems like it would make acquiring parts difficult

    im really digging this using a corolla front brake components to bolt onto the rear, im totally going to take apart my drum setup this week if i get bored

    1986-1991 Celica's had the same bolt pattern

    as do the 85-89 mr2's witch fastbrakes.com sells a rear brake upgrade for, that may be the way to go

    well my idea doesn't work. there's no way you can use the front components because there isn't enough space for installing a mounting plate. otherwise... it would work.

    the pots sit too close to the hub so there isn't much meat left between them. the metal would be too thin to support the force of the caliper braking

    I've been talking to Dr. Tweak. The setup would cost 500 bucks + shipping.
