okay today i was trying to change my rear brake pads.I took the caliper off the i used needle nose to turn the piston.problem is that the piston turned but it did not seem to be going in so i could put it over the pads.What am i doing wrong or did i just not turn it enough times??

 

you need to put some pressure when you turn that in

 

might be easier with the proper tool...

 

your local autoparts store has a tool that plugs into those divots on the piston on one end, and take a 3/8" extension to your ratchet on the other end. Even with this, you'll need to push it in and turn it quite a few times to get it in.

 

ok ill try that today thanks.

 

I've had them such that no matter how much I turned and pushed, they just never would go in. What I learned to do in that case is to turn them the other way until they come all the way out and let most or all of the fluid out. Then just put it back in, with the seals fitted properly on the piston and caliper, and it will then turn in and retract easily. Put it back together and bleed it, and it should be just fine.

 

The similar effect with less liquid spill could be achieved by putting some clear plastic hose on the bleeding screw and unscrewing it until liquid goes into the hose. Leave it like this and try to turn the piston in again. I found it goes in much easier on one of my calipers where it also refused to move in no matter what.

 

Yes, I've tried that, too. Sometimes it has worked for me, and sometimes it hasn't.

 

You did remove the cap from the brake fluid reservoir? otherwise you are going to have a hard time pushing the fluid back into the reservoir. Hope this helps.

 

i don't see how people used needle nosed pliers to twist in that caliper.. i've had a 5th gen and a 5.5 gen, and with both of them the piston was so hard to turn, i would have to exert ALOT of strength to get the thing to turn a small amount using the auto zone tool.. i would think the needle nose pliers would just snap, bend, or just not work
