1998 GMC SONOMA Service Brakes, Hydraulic Problems

IN APRIL 2006, A BRAKE LINE ON MY 1998 GMC SONOMA PICKUP BROKE WHEN I APPLIED THE BRAKES AT APPROX 50 MPH. I HAD TO STOP RATHER QUICKLY DUE TO TRAFFIC BACKING UP ON AN INTERSTATE HIGHWAY. WHEN THE BRAKE LINE BURST, MY BRAKE PEDAL WENT TO THE FLOOR AND I HAD NO BRAKES. PRIOR TO THIS HAPPENING, THE BRAKES WERE WORKING FINE. FORTUNATELY, I WAS ABLE TO SWERVE INTO ANOTHER LANE AND DOWNSHIFT (STD SHIFT) TO AVOID AN ACCIDENT. MY MECHANIC REPLACED THE BROKEN LINE (FROM HYDRAULIC ABS TO JUNCTION) AND ALSO THE REAR BRAKE PADS AND ROTORS. THE TRUCK HAD 107,000 MILES ON IT WHEN THIS OCCURRED. I DECIDED TO REPORT THIS BECAUSE I AM CONCERNED THAT IT MIGHT HAPPEN TO OTHERS, RESULTING IN A SERIOUS ACCIDENT.*JB

Mileage: 107,030

WHEN PARKING BRAKE PEDAL WENT TO THE FLOOR, CAUSING EXTENDED STOPPING DISTANCE. DEALERSHIP WAS NOTIFIED, BUT DID NOT RESOLVE THE PROBLEM. *AK

Mileage: 80,000

STARTED OFF WITH A SUDDEN FAILURE TO ACCELERATE ON HIGHWAY THEN CORRECTED ITSELF; ON AND OFF FOR A FEW WEEKS. DISCOVERED THAT BRAKE PEDAL WAS SOFT AND WAS FAILING TO RETURN TO STARTING POSITION; REPLACED MASTER CYLINDER TO ELIMINATE SOFT PEDAL BUT STILL STICKING AND NOT RETURNING TO STARTING POSITION. CANNOT FIND CAUSE. *NLM

Mileage: 57,000

THE ANTI-LOCK BRAKE SYSTEM LOCKED UP, WHICH RESULTED IN EXTENDED STOPPING DISTANCE.*JB

ANTI-LOCK BRAKES FAILED TO STOP WHEN PEDAL WAS DEPRESSED BUT DID GRAB ABRUPTLY. DISC BRAKES ARE ON THE FRONT AND REAR ARE DRUM BRAKES. PLEASE DESCRIBE DETAILS. *AK

WHEN APPLYING BRAKES IN SNOWY WEATHER THERE IS CLICKING SOUND PRESENT AND VEHICLE WILL NOT STOP. DEALER HAS NOT SEEN VEHICLE. *AK

WHEN HE APPLYING BRAKES ABS BRAKING LIGHT CAME ON. THEREFORE, SYSTEM WAS INOPERABLE. DEALERSHIP WAS AWARE OF PROBLEM. MECHANIC TOLD HIM THAT EBCM DEVICES WERE BAD .THIS WAS BRAIN UNIT TO THIS DEVICE. *AK

MY 1998 GMC SONOMA DEVELOPED A BRAKING PROBLEM - PULLING HARD RIGHT. THE VEHICLE (UNDER WARRANTY - 15,000 MILES) WAS TAKEN TO THE DEALERSHIP TO CORRECT THE PROBLEM. THE FRONT ROTORS WERE TURNED, PADS DEGLAZED, WHEEL BEARINGS REPACKED, REAR DRUMS TURNED AND SHOES ADJUSTED TO CORRECT THE PROBLEM. THE COST TO ME WAS $217. I HAVE NEVER EXPERIENCED BRAKE PROBLEMS AT SUCH LOW MILAGE ON ANY VEHICLE I HAVE EVER OWNED. I AM CONVINCED THAT A DEFECT EXISTS IN THE BRAKING SYSTEM THAT GM IS ATTEMPTING TO BLAME ON THE CONSUMER. *AK
