I am replacing the front disc pads on my 2000 TJ. In trying to
push/pry the caliper piston back into the cylinder it won't budge. I
removed the cap from the brake fluid resevoir and have a helper
watching to make sure there is no overflow when (if!) the caliper ever
moves...

Any ideas on how to get it to go back into the cylinder? I put a LOT
of pressure on it so can't figure out why it is stuck.

I'm not having any problems with braking in day to day operation.
Everything is working good the pads just need replacing.

Thanks!

Glenn

 

I use front end pliers to collapse the caliper while it's still
over the disk and old pads, with retaining bolts are removed. The
correct way is to use "C" clamp:

it drives the piston straight in to avoid cocking and jamming it in it's
cylinder, as you have found.

It often moves so slooowwwwly that you often don't feel like you're
compressing the piston at all. I just squeeze the brake pad back via its
two ends until the piston starts to move back... and it does take some time
and effort. I sometimes force them apart with some handy doo-dad laying
close by but most often, I just use my hands.

Thanks to both responses so far...they really helped...

and sorry about the double post...I didn't think I actually posted
this one.

The c-clamp I have done before but strangely...I was reading from a
Jeep Manual (chilton or haynes I forget which one) and it said to not
use a c-clamp on 1990 and later models. It said just use a
screwdriver...guess I let my head get stuck on that and didn't want to
use a c-clamp.
