Have a 96 Camaro RS Automatic 3.8L. Low Trac Light originally would come on when Stopping then going. Now the ABS light comes on when it wants to. When I slow down at a slow speed to stop, the pedal drops and the brakes fail and I have to hit the pedal again to stop completely. Did have Front Brakes & Rotors installed but did not solve the problem. Any Help? Thanks.
