MAJOR BRAKE FAILURE, IN SNOW, ON HILL, BRAKE PEDAL WENT TO THE FLOOR AFTER A LOUD RUMBLE FROM THE REAR OF THE TRUCK. HAD MASTER CYLINDER REPLACED, AND 10 DAYS LATER THE EXACT SAMETHING HAPPENED, DEALER INSTALLED ANOTHER MASTER CYLINDER. TEST DROVE, BLEW THAT CYLINDER, THEN REPLACED THE ABS MODULATOR ALONG WITH ANOTHER MASTER CYLINDER, AND SENT US ON OUR WAY. IT IS NOW TWO WEEKS LATER AND BRAKE FAILURE IS BEING NOTICED AGAIN, TRUCK IS SITTING CURRENTLY AT DEALERSHIP. ALSO, THE STEERING WENT VERY LOOSE AROUND SEPTEMBER 1998, HAD THAT CHECKED AND REPAIRED, AT THIS TIME THE STEERING IS AGAIN GETTING LOOSE. *AK

I AM A METICULOUS DRIVER. I HAVE BEEN THROUGH 2 SETS OF FRONT ROTORS, 4 SETS OF FRONT BRAKE PADS, AND THE REAR BRAKES STILL LOOK LIKE NEW. THE REAR BRAKES DO NOT WORK ACCORDING TO MANUFACTURER BENDIX; MANY ACQUAINTENANCES OF MINE HAVE THE SAME EXPERIENCE. I HAVE CONTACTED THE BBB AUTO LINE MANY TIMES AND GMC MANY TIMES; I AM NOW IGNORED AND GMC HAS WARRANTIED NONE OF THESE REPAIRS. THE BRAKING DISTANCE IS SIGNIFICANTLY INCREASED BECAUSE THE FRONT BRAKES ARE DOING APPROX 90 PERCENT OF THE STOPPING; PROBLEM IS WORSE WHEN THE BRAKES ARE HOT. P.S. I ENTERED THE VIN CORRECTLY BUT THIS PAGE WOULD NOT TAKE IT; I DOUBLE CHECKED. ????
