1991 GMC SUBURBAN Service Brakes, Hydraulic Problems

THE PROBLEM: THE SPEEDOMETER WORKS INTERMITTENTLY, THE BRAKE LIGHT WOULD COME ON, AND THE BRAKES WOULD LOSE POWER. I TOOK IT TO THE DEALER TO GET FIXED. THE BRAKE LIGHT DOESN'T COME ON ANYMORE. THE DEALER HAS CHANGED ALL THE COMPONENTS ON THE FRONT AND REAR BRAKES. NOW THE BRAKES ARE REALLY MUSHY AND THE TRUCK PULLS TO THE RIGHT. THE DEALER CHANGED THE SPEED SENSOR, BUT THE SPEEDOMETER DOESN'T WORK. MY TRUCK HAS BEEN AT THE DEALER FOR MORE THAN 2 WEEKS.

WHEN TRAVELING ON WET OR DRY PAVEMENT, UPON MAKING A GRADUAL STOP THE REAR BRAKES LOCK UP, VEHICLE JUMPS FORWARD. ABS LIGHT IS ILLUMINATED ON THE DASH. CONSUMER HAS CONTACTED THE DEALER, DEALER HAS REPLACED PARTS. *AK

WHEN BRAKING AT HIGH SPEEDS THE BRAKES FADE, CAUSING EXTENDED STOPPING DISTANCE. THE DEALER HAS NOT BEEN NOTIFIED. *AK

ANTI-LOCK BRAKES FAILED WITH PEDAL GOING TO THE FLOOR. *AK CONSUMER STATES WHEN BRAKE PEDAL WAS PUSHED, NOTHING WOULD HAPPEN AND THEN ALL OF A SUDDEN THE BRAKES WOULD KICK IN, DEALER HAS TURNED ROTORS TWICE, REPLACED ROTORS ONCE, REPLACED ABS BRAKE MODULE, AND REPLACED ABS PUMP VALVE. *SLC

THE ABS REAR BRAKES DID NOT PERFORM FROM TIME OF PURCHASE. WHEN YOU APPLY THE BRAKES ONLY THE FRONT BRAKES WORKED. CONSUMER STATES THAT THE REAR BRAKE NEVER WORKED.

ABS BRAKE FAILURE, RESULTING IN EXTENDED STOPPING DISTANCE WHILE DRIVING. *AK
