I know this has to be a simple fix, but I can not get the rear caliper piston to depress? I am using a C-clamp to try to get it to go down, but no luck.

Is there a particular way of depressing the rear pistons?

 

you have to rotate it in , there is a tool that you can buy at auto zone that comes in handy for this.....dont keep pressing them in otherwise you will F them up

 

Thanks man! This is my first time ever changing the rears and I thought it was exactly the same as the front. Apparently, it wasn't as I couldve damaged the piston.

Thank you again

 

Just grab a big flathead screwdriver and twist it in. No sense buying a tool when you already own one.

 

I used the flathead end of a cross-range to twist it back in.

Thanks for the input guys!
