Well it kind of depends on what the piston looks like. Does it have two holes on the head of the piston? If so, you will either need the special tool to compress it or you can try to use a set of needle nose pliers to push and turn it at the same time. If it doesn't have the two holes then all you should have to do is take the old brake pad and put on the piston (shim side to piston) get a C clamp and compress it (the brake pad will help protect the piston as well as help to provide even pressure across the piston as you compress). It may take some pressure but eventually you should see it start to compress. I have done several brake jobs myself and this way works the best. Hope this helps and goodluck.
note* - I have read that when compressing the piston you should have the bleeder screw open to allow some of the fluid to escape as you compress the piston. Also you could have the brake fluid reservoir cover open to allow for the fluid to escape that way. I have done both and they have worked fine for me.
No need to rotate the front caliper pistons as you compress the front calipers. That process is only for the rear calipers because of the parking brake mechanism.
the piston on the rear calipers will turn in a clockwise motion and that is how they retract.
Some Ford's rear calipers have to be turned in like a screw instead of pushed in like "old fashioned" calipers. I went to Auto ZOne with the same problem and the guy knew exactly what to give me. It's a little adapter that helps you turn the caliper.
I use a "C" clamp but a big set of channel lock pliers works good too.
Unlike the front calipers, pistons in the rear usually have to be rotated to compress them.
NO! Brake Calipers are what compress your Brake Pads on to the rotor which turn simeultaniously with your wheels.
Yes. If your question is regarding the operation of the calipers. They do operate in the same manner as the front calipers.
Push in. I've change my front pads several times and they compress straight in.
First you have to take the calipers off. Then compress the piston and lift the caliper off. Then you pull remove the springs to get the pad off.
are u trying to change them?
Try exerting pressure while turning clockwise to retract
