Question for those who have changed rear brakes....

Not quite sure what the problem is, but I took off my rear brake calipers today to finish installing my 3 inch wheel studs, and when I went to put them back on I didnt compress the piston (didnt have the tool) It was REALLY tight, but it went back on ok....seemed ok.......


WELL, when I went for the test drive my brakes are smoking from that caliper now. ???

Did I screw them up somehow? or do I need to compress them, then reinstall? I cant figure out why it is rubbing?

It was tight as hell going back on, but it did go. The other side went on alot easier.


HELP ME PLEASE.

thanks.

Try and turn that piston in somehow, i used the tool but some say you can do it without.

I can rent the tool tomorrow Bob, I was just wondering if you thought I needed to or if it sounded like the caliper was frozen up somehow?

some times the tool doesn't work w/out some modification. heres what I did on my 95. With a shop rag over the dust boot use a good set of channel locks to turn the piston in while turning on a c-clamp (to compress it like the front) turn it a few times and add more pressure w/the clamp. you should be good to go after that.

I understand HOW to collapse the piston... I got the brakes back on without doing it, now one of them seems to be stuck against the rotor. It is smoking and getting REALLY hot.

My question was....Do I have to collapse the piston to may it operate properly, or could it just be coincidence that it seized up now?

That's what I did on mine too.

sounds like the caliper could be locked up, i would try and compress first...but its possible that it seized.

Yeah I dont know who thought putting screw style pistons in the rear was a good idea but I'd like him/her to be tar'd feather'd and ridden out of town on a rail.

OP my apologies for misunderstanding your post.

Your caliper/s probably failed on you or seized up.
Don't risk your saftey replace the caliper/s.

Thanks for all of your responses Guys :) there is a pending sale on the car, so I dont want to take any chances. the guy told me he would pay for a new caliper, so I am going to just replace it I think.
