I just did the rears (replaced a caliper, both rotors, and pads). I've always had crappy braking before, and doing this hasn't affected much. I have a 93 with ABS, so I followed the haynes instructions, "primed" the abs, bled the brakes, and bled the ABS module. Everything according to instructions, and got all the air out. But it still feels spongy, and the pedal goes 75% down to the floor before braking occurs... It would be impossible for air to still be there - I bled it twice, and did the "start engine to initialize ABS to free air bubbles" procedure twice as well. Do I need a new MC? Do you still think there's air in it?

Okay now, that's enough of that. -
Did you adjust the rear piston out to the pads correctly? If i remember right, you have to do this or else the brakes don't work good at all..

I haven't done it before myself, but a friend told me about somethin with turning the piston back out somehow in the back to properly adjust the rears so the pedal feel was normal..

When I replaced my front rotors I just took the cap off the master cylinder and used a C-clamp to push the piston back... worked for me. That should work for the rears as well.--Rob

Yep, that's what I did. I took it to a shop to have them test drive it, and they were like, "the brakes are fine... I've seen much worse"... I guess I just demand higher standardsOriginally posted by blk92z34getrag
I'm gonna replace the front rotors and pads, anybody know what size Torx bit the caliper mounts take? It's huge - larger than my bigest T50...

To set rear piston simply activate the park brake several times, and after each set push and hold the brake pedal for 10 seconds or push the pedal while setting the park brake. 5 reps should do it, then re-check for air in the caliper or dirty oil and bleed off some oil for giggles, then set the rear park break a few more times and it should be good.I am back

It's a T60, your best bet is to go to a bargain tool store and get a brake socket set. It will be cheap and will have a T60 in it.anybody know what size Torx bit the caliper mounts take? It's huge - larger than my bigest T50...

Got it. Replaced the rotors and pads in front, and I'll try that technique to set the rears tomorrow. Fun fun!Originally posted by Lyle's GTPOkay now, that's enough of that.Comment

You used a C-Clamp to compress the piston in the rears? Something's not right here...
For the rears you should have to turn the piston while pushing to get it in correctly...

Well, technically it did turn as it went in.. at least the right did, I replaced the left with a new caliper so it was ready to go.Originally posted by Cliff8928Okay now, that's enough of that.Comment
