1995 GMC SUBURBAN — SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

THE ANTI-LOCK BRAKES HAVE "GONE TO THE FLOOR ON SEVERAL OCCASIONS THE LATEST RESULTING IN AN ACCIDENT. THIS HAS ONLY HAPPENED AT LOW SPEEDS (UNDER 30 MPH). I HAVE REPLACED THE BRAKE PADS THREE TIMES AND THE REAR DRUMS ONCE. NOW THE MASTER CYLINDER IS BAD AT 85,000. IS THIS COMMON TO ALL GMC SURBURBANS? IN 1994 GMC TOOK BACK A SURBURBAN BECAUSE OF MULTIPLE BRAKE FAILURES IN A LEMON LAW SITUATION. THE 1995 REPLACEMENT IS NOW HAVING PROBLEMS INCLUDING A MASTER CYLANDER FAILURE. IS THIS COMMON WITH OTHER GMC SURBURBAN OWNERS? *AK
