VIN # for rear disk brake option

[hockeyman]

I went to the dealer today to get a spring for the rear disk brakes and the guy told me he could only look it up for my car if the vin # called for it. If there is anyone here that has stock rear disk brakes, can you please give me you vin # so I can get this part. I'm going to make a return trip tomorrow morning.
The problem is when I'm driving, my rear brakes chirp everytime the wheel turns. When I hit the brakes, it goes away, then when I let my foot off the pedal they start chirping again. I put new pads on this past july.
Thanx,

Just out of curiosity... have you checked to make sure everything is straight and true?? Sounds like something is "tweaked" out of place. Could be a rotor or even a caliper bolt. For that matter, could be the caliper being sticky.

I've had my 94 Z rearend in for over a year now with no issues... well, other than that god awful whine from back there :D ;)

No, I haven't checked everything under there. Maybe I should take the rotors to Pep Boys first to have them re-surfaced. How would I go by cleaning the internals of the calipers?
Hey Tealv6, I put a new rear in my 86 T/A about 6 years ago because the whine from the rear was getting on my nerves. It turned out to be the bearings behind the yolk that were going bad, and the shop wanted way too much $$ to fix it so I just replaced the whole rear.

Can't hurt to have the rotors turned unless you are pushing the limits. Most places charge about 10 bucks per. While your at the parts store, you can get a caliper rebuild kit. Those are also cheap. Just have to pull the main piston out and clean it up, put the new O-rings in and new mount sleeves. If that does not fix the problem, put the rear up on stands and see if the alxes are straight by free spinning the wheels. Not likely, but nothing to try.

Got my project for tomorrow. Also, I don't think the axles are bent. I had my car up on the highway quite a few time pushing 95 mph and there isn't any vibration. I'll check them anyway.
Thanx Steve.

Hey hockeyman, I haven't got around to buying the springs yet. I just try not to use the parking brake as much as possible. If you can get to the rear brakes from the rear of the car, you can loosen up the brake cable's tension on the brakes. They'll stay loose until you pull your parking again. But thats only a temporary solution. :(

Hey Dojo2000 and TealV6,
I found the problem!! The two slide bolts that hold the caliper(s) on are supposed to be well greased. You know the one bolt you remove to swing the caliper open? Well that one and the other one just below it are supposed to be greased so they slide smoothly. I took the passenger caliper apart first and regreased all moving parts. Then when I did the drivers side, I saw the problem. The one bolt holding the lower part of the caliper was Bone Dry, initially not letting the caliper slide open or fully disengage.
I bought a rebuild kit for the rear calipers for 8.99 a piece, but all it gave me was the two bolts and two rubber bushing for each rear caliper. I'm taking them back in awhile because I didn't need them.

Glad you found the fix. Just a little work and you can do most anything ;)
