1994 CHEVROLET BLAZER — SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

AT LOW SPEED, APPROXIMATELY 30MPH, I HAD TO STOP SUDDENLY. AT THE FIRST INSTANCE OF BRAKING THE BRAKES BEGAN TO STOP ME. THEN THE BRAKE PEDAL WENT SLOWLY TO THE FLOOR AND BRAKING CEASED. I REAR ENDED THE VEHICLE IN FRONT OF ME AT APPROXIMATELY 10 MPH. THE ABS FAILED IN SIMILAR CIRCUMSTANCES IN MARCH OF 1995, ALSO CAUSING A REAR-END COLLISION. THIS INCIDENT WAS ALSO REPORTED TO THE NTSA AS WELL AS TO CHEVROLET. AT THAT TIME THE BRAKES WERE INSPECTED BY A CHEVROLET DEALERS SERVICE DEPARTMENT. CHEVROLET MADE THE DETERMINATION THAT THERE WAS NOTHING DEFECTIVE ABOUT THE BRAKES. THIS PROBLEM DOES NOT APPEAR TO BE CONSTANT AND IS APPARENTLY NOT REPEATABLE ON DEMAND. *AK
