hello, i am working on a 99-04 car. it is making a rubbing noise on the left rear. i took the caliper off and drove the car without it and no noise. so i go to compress the caliper in to put it back on the car and it won't budge. i open the bleeder and try it and it won't even budge, no fluid is being shot out. so i open the master cylinder cap and it had some pressure behind it. the caliper compressed a little after that but it stopped. so i opened the back line at the proportioning valve and now the caliper would compress easily and fluid is squirting out. there is something wrong with that one brake because it makes a screaching noise when going slow, it is sticking. does this sound like a bad caliper. i don't think it is the proportioning valve because only one side of the back brakes is making a noise.
Sounds like it, especially if it won't compress with a c-clamp after being removed. Their not expensive to replace so try that route. Let us know.
You do realize that the rear caliper has to be compressed while turning to go back into the housing right? That could be your problem. You are not turning and compressing at the same time to recess the caliper. T
I had the same problem last night while attempting to install pads on my daughter's 95. The rear caliper simply would not compress.....! I did not know about having to turn the caliper piston while compressing it. How exactly do you accomplish this? Thanks, HYS
you go to Autozone and request part number 27111, it is a piston compression tool. It fits into the groove on the piston and compresses while turning. T
