We're working on an SS/SC trying to change pads and rotors. In removing the driver's side rear, we can almost get it BUT the piston in the caliper WILL NOT compress, we've tried a little bit of everything, c-clamps, etc. We were trying to avoid taking any lines off, but we even tried that in hopes that it would help us get the piston compressed. E-brake is fully disengaged, that was the first thing we checked. The car must be back on the road TONIGHT, so we need some help if anyone knows what to do.

 

i just use a c clampand that always works for me but you said that dident work did u try to use a actull piston compressor

 

The rear brake pistons have to be turned clockwise while pushing in. They make a tool for it....I just used a pair of needle nose pliers and turned. Its awkward but works.

 

Yeah the piston in the rear is like a screw. I have a sweet ass air tool that makes it so simple at work.

 

You don't have to remove any lines, and that wouldn't help anyway. Try taking the cover off your brake fluid resevoir under your hood. That might be holding some pressure against you. Try again.

 

It overflows if the pressure it too high. I found this out today also.

 

Yeah it will usually overflow on you, but break clean will fix that up for you

 

Right after we posted this we figured out the rears were screw in type. Thanks for the help though.

 

yeah i had this same trouble but my dealer took care of it and gave the special tool for free
