PARKING BRAKE
NOISE WHEN TURNING STEERING WHEEL TO THE RIGHT, SOUNDS LIKE A SQUEAKY DOOR ONLY LOWER FREQUENCY. TOOK TO DEALER ON MAY 22, 2008, WAS TOLD IT WAS THAT THE INTERMEDIATE STEERING SHAFT WAS LOOSE. I HAD THIS UNIT CHANGED ON MAY 22,2008. ON JUNE 5, 2008, I TOOK THE VEHICLE BACK TO THE DEALER FOR BRAKE WORK WHICH CONSISTED OF REPLACING REAR BRAKE PADS,ROTORS, & EMERGENCY BRAKE LININGS. SINCE THE STEERING WAS STILL MAKING NOISE I HAD THE DEALER CHECK IT AGAIN, THEY DID AND LUBED THE STEERING SHAFT COVER. STILL MAKES NOISE DOES NOT APPEAR TO AFFECT STEERING. ON EA04011 THERE WAS A RECALL FOR MANUAL TRANSMISSIONS IS THIS NOW IN EFFECT FOR AUTO TRANSMISSIONS? ON SEPT. 3, 2008, THIS VEHICLE WAS TAKEN BACK TO DEALER FOR REPLACEMENT OF EXHAUST MANIFOLD GASKETS AND BROKEN BOLTS ON MANIFOLD AND ALSO FOR LEAKING WATER PUMP GASKETS ARE THESE NORMAL WEAR OR MANUFACTURING DEFECTS? NO OLD PARTS AVAILABLE FOR INSPECTION, REPAIR TICKETS ARE AVAILABLE.

PARKING BRAKE
PARKING BRAKE (E-BRAKES) FAILURE OF CHEVY SILVERADO 1500 Z71 WITH 4-WHEEL DISC ABS BRAKES. TRUCK PURCHASED NEW FROM FAMILY CHEVROLET IN SHINGLE SPRINGS CA. E-BRAKES NEVER WORKED FROM DAY ONE, HOWEVER, I WAS TOLD THIS WAS HOW THEY FUNCTIONED DUE TO 4-WHEEL DISC SYSTEM (FROM DEALERSHIP)-WRONG. AFTER ASKING OTHER CHEVY TRUCK OWNERS WITH THE SAME E-BRAKE SYSTEM, THEY TOO EXPERIENCE THE SAME PROBLEMS. I AM VERY SURPRISED THAT GM DID NOT SEND A RECALL NOTICE OUT FOR THIS PROBLEM. THOUGH GM DID SEND OUT A RECALL ON THE TAIL GATE SUPPORT CABLES, I FIND THIS PROBLEM MUCH MORE OF A SAFETY PROBLEM SINCE THE E-BRAKES ARE SUPPOSE TO HOLD BACK A 2 TON VEHICLE OF WHICH IT DOES NOT. A MECHANIC FROM LES SCHWAB TIRES (AND BRAKES) TOLD ME AFTER HE INSPECTED MY E-BRAKE SYSTEM THAT HE HAS SEEN THIS PROBLEM CONTINUOUSLY OCCURS WITH THIS TYPE OF E-BRAKE SYSTEM WITH GM TRUCKS.

SERVICE BRAKES, AIR:ANTILOCK:WHEEL SPEED SENSOR
2002 Z71 SILVERADO CHEVROLET TRUCK PERTAINING TO ANTI-LOCK BRAKE FAILURE: ONE MONTH AFTER WARRANTY EXPIRED THE FAILURE OCCURRED. THE PROBLEM RESULTED IN UNWANTED ABS ACTIVATION AND INCREASED STOPPING DISTANCE DURING LOW-SPEED BRAKE APPLICATION. GM INDICATED THAT THE CONDITION CAN OCCUR IF CORRISION FORMS UNDER THE WHEEL SPEED SENSOR AND MOVES THE SENSOR AWAY FROM THE INTERGRAL SPEED SENSOR TOOTHED RING. THE CONDITION DOES NOT SET ANY ABS CODES NOR DOES IT ILLUMINATE THE ABS WARNING LAMP. IT IS OBVIOUSLY A MANUFACTURER'S MALFUNCTION MAKING IT VERY DANGEROUS TO DRIVE. I PERSONALLY KNOW OF SEVERAL PEOPLE WHO HAVE HAD THE SAME PROBLEM.

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP
BRAKES WERE SERVICED, HOWEVER THEY DID NOT STOP THE VEHICLE. ANOTHER DEALER STATED NO DEFECTS WERE FOUND. THE PEDAL WENT TO THE FLOOR. ALSO, AFTER CHANGING THE OIL THERE WAS METAL FOUND IN THE OIL. *AK THE DEALER STATED THAT METAL IN THE OIL WAS NORMAL THE BRAKES FELT SPONGY. THE CONSUMER STATED THAT METAL IN THE OIL MEANS THE ENGINE WILL NOT LAST.

THEY WORE METAL TO METAL WITH STILL NO SIGN OF FAILURE, UNTIL THE CONSUMER ATTEMPTED TO USE THE PARKING BRAKE AND IT DID NOT HOLD.
