1993 Pontiac Grand AM mileage: 95,000. When I push on the brakes, the rear brakes (ABS) lock up. I inspected the brake pads and shoes along with the drum and rotors and all are fine. I suspect the proportioner valves in the master cylinder. Am I on the right track or is their something else I need to be looking into? Thank you.
have the same problem?
