Re: '00 GJC uneven break wear
Thanks for the replies.
I'm pretty sure the pads are installed correctly. Not sure if there are
slide pins or not. I distinctly remember cleaning pins, but I think
that was on my Explorer. I put new pads and rotors on that a few months
back.
I didn't get time to tear into the brakes this past weekend. I'm sure
when I do, I'll just replace the rotors and pads and whatever else
looks worn. Not sure how to tell if the calipers themselves are working
properly. Seems like if the pistons are 'hard' to compress that there
might be a problem. But how do you define "hard"?
Is there some way to tell if the pistons are sliding in and out easily?
The local auto parts store sells a kit that includes rebuilt calipers,
all the hardware and pads for something like $120 each.

Re: '00 GJC uneven break wear
The caliper should slide freely on the pins. Basically, if you can see
grease all over them, that's good enough. If you cant, make it so.

Re: '00 GJC uneven break wear
The caliper should slide freely on the pins. Basically, if you can see
grease all over them, that's good enough. If you cant, make it so.

Not rilly. If they just fall back in then there is a problem
which can usually be found by looking for a big puddle of brake
fluid. :) That's why it takes a C clamp to push the piston
back in. Your squeezing a lot of fluid through a little line.

I wouldn't go with a rebuilt caliper till you see what the pistons look
like. Oh.. and never push on the brake with the caliper not on the disc
and shoes in it. That will pop the piston out and make one hell of a mess.
