Hello, I am having problems installing the rear rotors and pads, for some reason i cannot get the rear caliper to compress no matter what i do. Im using a C- Clamp just like i did when i installed the Front rotors a few hours earlier today. Can someone help me do this so i can finish it today thanks.

you have to twist the piston in. cant just push

 

You can rent the tool at autozone i think.....

 

you may have ruined the rear calipers if you tried to force them in. Twist my friend. I have also seen some guys use a pry par like a big screw driver and screw them in. thats what the groves are for in the piston.
