Im replacing my rear brake pads, I cant push the rear brake piston in to put new brake pads, using a C clamp, i did my front brakes awhile ago and the piston went in easily. Does anyone know what i have to do? ive never done rear brakes before, plz help!

 

you can rent a tool to help with that. autozone has the tool, check it out

 

the piston has to be screwed in clockwise while your pressing it in because of the E break that's how they adjust

 

^^^^^ yup a big hex key or is it an allan wrench
