Question
the rear disc brakes do you need a special tool for the calipier it looks  like it might screw in instead of being pushed in. thanks joe

Answer
Yes, the rear pistons screw in as they are compressed.  Go to Autozone, Pepboys or the like and they have the tool for about $20 bucks.  All you do is compress the piston like the fronts while you screw the piston in clockwise until it stops.  Be sure that the groove on the piston lines up with the pins on the back of the pad.  The grooves need to be up and down to line up with the pins on the back of the pads.
