Cant get 1 brake caliper piston to recede back in
 

Really need advise please!!!!
At first both pistons were stuck out. I got 1 of them 100% back in by just prying it with a flat blade screw driver but the other wont go back enough to put a brake pad in.

Thanks in advance

If it is the front (and they are like mine) you can use something like this, or you can use a C clamp. I have this tool, but I used to use a big channelock pliers, with tape around the jaws. If it is the back it is a little trickier sometimes, depending on the caliper design.

I'm sorry guys it is the rear. I tried a screw driver. I'm thinking of trying a pry bar. I probably need new calibers

Use a C-clamp against the old brake pad to push it back in, be careful to not cock it in the bore.

Thanks guys. Somebody suggested a pry bar between the old pads. That is what finally worked. At first it still wasnt budging but then finally it moved. Still was a tight fit with the new pads on one side but they are in there. Probably should get new calipers and rotors when I can. :)

You can't use a C-clamp on the rears on those. They are closed on both sides. You need a special spreader, or... pry bar...

The pry bar did the trick. :)

spree17, only replace the rotors if they are near or below the minimum thickness, or they are warped.

It's possible that you could free a sticky caliper piston by cycling it several times. Fully retract the piston, install the worn brake pads then press the brake pedal so the brake pads grip the rotor. Repeat several times and see if the piston gets easier to retract. If not, then you will need to replace/rebuild the caliper.

Thanks for the advice. I will try that. :)

i agree with the last post,if its stuck in the out position,it may be for a reason,just because your able to force it bacl in,does not mean its going to slide in and out smoothly,if it is hard at all coming out,then you jammed it closed using to much pressure,i would suggest replaceing the calipers,or rebuild them both,the piston should not bind upr have any pressure against it,work it like he said in and out,free smooth peration should be,if not,fix them.

These are just hard to do since the caliper is closed on the other side so you can't get any leverage. I don't think the caliper is bad. He just didn't have the correct tool.
