Rear brake change problem, need help fast.
 

im trying to change my rear brakes and after gettin the old pads off and the new ones on i cant get the caliper back on, the piston is out too far and wont go back in with the c clamp. what do i do?

you need to screw them back in, they won't compress... turn them like a screw back in..

you are right, thanks! :)

You need a good set of needle-nose pliers or the proper piston tool to get the piston to rotate. It goes clockwise.
