I've replaced one before but I cannot remember if the piston on the rear brake caliper of a 94-98 push in or if they are the screw in type. I tried turning mine last night but it didn't seem to go in any. Could someone please refresh my memory? Thanks!!

 

You need to rotate the piston clockwise and push it in then align the notches on the piston with the marks on thecaliper. Needle nose pliers will work.
