2004 CADILLAC CTS — SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:MASTER CYLINDER

I WAS IN THE RIGHT LANE OF A HIGHWAY LEADING TO AN OFF RAMP AT ABOUT 35 -40 MPH WHEN TRAFFIC STOPPED SUDDENLY. WHEN I JAMMED ON THE BRAKES THE PEDAL WENT UNUSUALLY LOW, THE ABS ALSO SEEMED TO FAIL RESULTING IN THE BRAKES LOCKING, CAR SKIDDING AND CONSIDERABLE STOPPING DISTANCE (WELL OVER 100FT). I HIT THE BUMPER OF THE CAR IN FRONT OF ME AND SLID INTO A CURB. CAR WAS TOWED TO A DEALER WHO NOTED THAT THE MASTER CYLINDER WAS SHOT AND THE BRAKES WERE SPONGY. I'VE CONTACTED GM BUT THEY HAVE NOT YET RESPONDED TO MY COMPLAINT. *AK
