6G Celicas Forums

My daughter and bf did a break job on the 99 GT last night. They noticed that the back pads that were on it were worn at an angle.

When the new pads (wagner) went on the back, they only had one shim....once they went on, they still made noise (rubbing) on the test drive....so my bf greased the slider pins...they still make a little noise at low speeds.

Anyone have any idea what else could help?

Did you grease the rear of the pads where the piston makes contact? Otherwise, I'd wager at a seized caliper.

They didn't grease the rear of the pad....that could make the pads wear at an angle?

What do you mean by seized caliper...? The bf said the piston IS moving.

grease????? dont you just put the 2 backing plates back where they were and put the pads back in and pop the clips back on?

isnt it more likely that you drove through a puddle with hot rotors, warped the rotors, and thats why the pads are wearing uneven

either that or the car is in need of a wheel alignment pretty bad?

did you notice if it was difficult to press in the pistons? how are the slider pin lubrication? greasing the shims are more for squeak prevention.

Easy killer, I just bought the car....I don't know if it was driven through water or not, but not since I have had it (a couple weeks).

It doesn't need an alignment.

The uneven pad wear is from the slider pins starting to seize up. The slider pins are different from the piston. Mine had the same exact problem, the insides were wearing more than the outsides and they were also wearing at an angle too.

Did greasing the slider pins fix your problem? We did that and it definitely improved.

Lower slider pin received new grease. The piston seemed to press in normally and we verified the piston came back out via normal brake use. I wonder if the top slider pin could be suspect. Anyone have experience with removing this pin since it does not have a bolt head on it?

Both the front and rears have two slider pins. The one rear one is a bolt-on, which the rear caliper slides onto and the other one goes through the caliper and the bolt goes through that. That is the only that usually seizes up in the rear.
As for the front, they should just pull right out. If they won't twist or move and you can hit them out with a flathead and mallet, then it's most likely seized too.
