Hello, I need some help. I have a 1996 Chevy 1500 Suburban. My right side break caliper locks up on me. I have already changed the caliper, rotor, master cylinder and abs sensor behind the rotor. It worked for about 2 weeks and it started locking up on me again. The plastic abs sensor behind the rotor gets melted, due to the heat from caliper locking up. Does anyone have any suggestions? Could it be the ABS unit/module. Please help me.
