o k my front pass. side pads are constantly pushing on the rotor, even when im not pressing the brakes. this is causing everything to get boiling hot while driving and smoke starts to come from my wheel. everyone told me that the piston inside of the caliper was sticking so i went out and bought a brand new caliper and a brand new brake hose. installed both of them and the same thing is happening. that piston,"the one you use a C-clamp on to compress" is not releasing pressure when i let off my brakes and is pushing the back pad against my rotor constantly. WHY?? i replaced everything and it is still doing this. someone please let me know how to fix this. thanks alot.
