I installed new break pads in the front rotors of my 1995 Pathy.
I had a tough time compressing one of two pistons in the right dual piston caliper and I think I may have screwed up one or both pistons.
I took the Pathy for a test ride and the right rotor and caliper got VERY hot to the touch (in comparison to the left wheel rotor/hub). I jacked the front-end up with both wheels off the ground and turned both wheels by hand. The left wheel turned easily, but I could feel the brake pads dragging on the right wheel. I knew it was the pads since I had compressed the pistons before applying the brake and the wheel turned easily.
I suspect one or both pstons are not pulling back from the right rotor and friction heat is building up in the rotor and hub.
I'm pretty sure I screwed the piston(s) compressing the right wheel caliper pistons individually. The bottom piston compressed OK after some work. The top piston would not go in at all after several tries. It wasn't until I installed the inside break pad, and used two C-clamps to push in both psitons at the same time that it compresssed so I could get the caliper around the new (thicker) pads.
I'm guessing I distorted the shape of the piston(s) and/or the cylinder(s) each piston moves in trying to compress the pistons individually.
QUESTION: Do I need to just replace the caliper pistons, or do I have to replace the entire caliper assembly? Can I get a caliper rebuild kit from an auto parts store, or do I have to go to a Nissan dealer??
TIA for any tips, suggestions, coments.
