1992 CHEVROLET SUBURBAN — SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

ABS SYSTEM FAILS TO OPERATE RESULTING IN BRAKE PEDAL GOING TO FLOOR, COMPLETE LOSS OF BRAKING, AND A LOUD SQUEALING NOISE FROM THE UNIT. IN PRIOR INCIDENTS TO 2-12-99, VEHICLE HAS BEEN PUT UP ON CURB AND HOMEOWNER'S FRONT LAWN TO AVOID REAR END COLLISIONS. ON 2-12-99 REARENDED A PICKUP TRUCK THAT STOPPED SUDDENLY IN FRONT OF ME. HAD AT LEAST 50 FEET OF STOPPING DISTANCE. WHEN CHEVROLET DEALER WAS QUESTIONED ABOUT SUBURBAN ABS PROBLEM, OWNER WAS TOLD PROBLEM DOES NOT EXIST. SYSTEM IS SUPPOSED TO ACT LIKE IT DOES AND SQUEAL IS NORMAL. UNLESS ABS LIGHT COMES ON, IT IS NOT VEHICLE ERROR. MASTER CYLINDER HAS BEEN REPLACED ON VEHICLE, BUT DANGEROUS SITUATION CONTINUES TO PERSIST.
