BOTH REAR HYDRAULIC BRAKE LINES RUPTURED AT THE FLARE FITTING ENTERING EACH CALIPER WITHIN 2 WEEKS OF EACH OTHER. THE DEALER WAS UNABLE TO REPLACE THE FIRST ONE, RIGHT REAR, BECAUSE CHEVROLET INFORMED THEM THAT "THE PART DID NOT EXIST!" THE DEALER WAS FORCED TO REFLARE THE OLD LINE. WITHIN 1 WEEK, IT BROKE AGAIN IN THE SAME SPOT. I REPLACED THE LINE WITH AN AFTERMARKET ONE MYSELF. LESS THAN A WEEK LATER, THE OTHER REAR BRAKE LINE (LEFT REAR) RUPTURED AT THE FLARE IN THE SAME SPOT AS THE RIGHT REAR, ENTERING THE CALIPER. I REPLACED IT MYSELF AND TOOK THE OEM BROKEN LINE TO VIVA MOTORS TO INFORM THEM TO INFORM CHEVROLET THAT THERE WAS A POTENTIAL SERIOUS DEFECT IN CHEVROLET S-10 REAR BRAKE LINES. THE SERVICE MANAGER ADVISED ME TO CALL CHEVROLET MYSELF SINCE THEY (CHEVROLET) WOULDN'T LISTEN TO HIM. SINCE CHEVROLET'S SOUTHWEST AREA ZONE REPRESENTATIVE HAD PREVIOUSLY TOLD ME TO "GO POUND SAND" I FIGURED WHY BOTHER WITH HIM. I FEEL THE ODDS OF TWO OEM BRAKE LINES FAILING WITHIN 2 WEEKS OF EACH OTHER ARE ASTRONOMICAL AND SINCE CHEVROLET CHOSE TO IGNORE THE INCIDENTS, I'D BETTER CONTACT YOU TO INVESTIGATE FURTHER. HOPEFULLY, MINE WAS AN ISOLATED CASE BUT I DOUBT IT BECAUSE AS I SAID, THE ODDS ARE ASTRONOMICAL AND THE SW AREA ZONE REP CHOSE TO SAY THE PART DIDN'T EXIST RATHER THAN ADMIT HE HAD A SERIOUS LIFE THREATENING PROBLEM. IN REALITY, HOW CAN HE SAY THE TRUCK NEVER HAD BRAKE LINES? I SMELL A RAT AND WOULD LIKE YOUR ORGANIZATION TO CHECK INTO IT. IF FURTHER INVESTIGATION SAVES 1 LIFE, THIS IS WELL WORTH OUR EFFORTS. FORTUNATELY, I WAS ABLE TO STOP SAFELY BOTH TIMES MY HYDRAULIC SYSTEM SUFFERED MASSIVE FAILURES BUT I WILL SAY, I THINK THE FAILURES TOOK A FEW YEARS OFF MY LIFE AND ABSOLUTELY CAUSED SOME SOILED PANTS. I'M NOT A CHRONIC COMPLAINER BY ANY STRETCH OF THE IMAGINATION BUT I'M NOT STUPID EITHER AND CHEVROLET HAS PROBLEM WITH AT LEAST ONE OF ITS TRUCKS AND IS CHOOSING TO HIDE ITS HEAD IN THE SAND IT WANTS ME TO GO POUND. THANKS FOR YOUR EFFORTS, JOHN MULLEN. *AK

MY SON WENT OVER A BRIDGE AND THE BRAKES MADE A LOUD NOISE, ENGAGED AND CAUSED HIM TO FISHTAIL AND RUN HIS FRONT END INTO THE BRIDGE. HE HAD A WITNESS BEHIND HIM THAT SAW THE WHOLE THING AND SAID IT WAS VERY SCARY AND A GOOD THING THERE WAS NO ONCOMING TRAFFIC. IT DID $2300 WORTH OF DAMAGE AND HIS AIRBAGS DID NOT EMPLOY. *AK

Official recalls
4Sep 8, 2000
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES WERE BUILT WITH INCORRECT PAYLOAD INFORMATION ON THE VEHICLE CERTIFICATION LABEL. THE PAYLOAD SHOWN ON THE LABEL IS GREATER THAN THE MAXIMUM VALIDATED PAYLOAD. IF THE VEHICLE WERE LOADED TO THE INCORRECTLY LABELED PAYLOAD, IT MAY NOT RIDE AND HANDLE IN THE MANNER THAT THE DRIVER EXPECTS.
Consequence & remedy
Consequence: THIS COULD RESULT IN A LOSS OF CONTROL OF THE VEHICLE OR AN INABILITY TO STOP THE VEHICLE WITHIN EXPECTED STOPPING DISTANCES.
Remedy: OWNERS WILL BE SENT A NEW LABEL FOR INSTALLATION ON THE DRIVER'S DOOR OF THE VEHICLE.
Aug 7, 2000
VEHICLE DESCRIPTION: PASSENGER VEHICLES, LIGHT DUTY TRUCKS, SPORT UTILITY VEHICLES, AND MINI VANS EQUIPPED WITH TRW SEAT BELT BUCKLE ASSEMBLIES. THE BUCKLE BASE OF THESE SEAT BELT ASSEMBLIES WERE NOT PROPERLY HEAT TREATED AND THEREFORE DO NOT PASS THE LOAD BEARING REQUIREMENT OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 209, "SEAT BELT ASSEMBLIES."
Consequence & remedy
Consequence: IN THE EVENT OF A VEHICLE CRASH, THE OCCUPANT MAY NOT BE PROPERLY RESTRAINED.
Remedy: DEALERS WILL INSPECT THE VEHICLE'S SAFETY BELT BUCKLE ASSEMBLY DATE CODES AND, IF NECESSARY, WILL REPLACE ANY SAFETY BELT BUCKLE ASSEMBLY.
Feb 28, 2000
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS EQUIPPED WITH 4-WHEEL DISC BRAKES. SOME OF THESE VEHICLES HAVE AN ANTILOCK BRAKE SYSTEM (ABS) MOTOR CONTAINING AN OUT-OF-SPECIFICATION SPRING CLIP. THIS CLIP COULD ALLOW THE MOTOR BEARING TO BECOME MISALIGNED. IF MISALIGNMENT OCCURS, EVENTUALLY THE ABS WOULD BE NON-FUNCTIONAL.
Consequence & remedy
Consequence: THE BASE BRAKES WOULD REMAIN FULLY FUNCTIONAL, BUT THE DYNAMIC REAR PROPORTIONING (DRP) SYSTEM, WHICH OPTIMIZES FRONT TO REAR BRAKE BALANCE, WOULD BECOME INOPERATIVE.
Remedy: DEALERS WILL REPLACE THE BRAKE PRESSURE MODULE VALVE ASSEMBLY.
Aug 11, 1999
VEHICLE DESCRIPTION: S -TRUCKS EQUIPPED WITH 2 WHEEL DRIVE. THESE VEHICLES MAY HAVE HAD THE RIGHT-HAND ANTILOCK BRAKE SYSTEM (ABS) MODULE FEED PIPE AND/OR BRAKE CROSSOVER PIPE TUBE NUTS TIGHTENED WITHOUT SEATING THE PIPE-FLARED-ENDS ENOUGH TO WITHSTAND NORMAL ASSEMBLY AND VEHICLE INPUTS WITHOUT PARTIALLY UNSEATING. THIS DOES NOT COMPLY WITH REQUIREMENTS OF FMVSS NO. 105, "HYDRAULIC SERVICE BRAKE NORMAL, EMERGENCY, AND PARK BRAKING PERFORMANCE."
Consequence & remedy
Consequence: IF THIS OCCURRED, THE SEATING SEAL COULD BE BROKEN DURING VEHICLE ASSEMBLY, OR FROM EARLY ROAD INPUTS OR BRAKE FLUID CYCLING, AND A LEAK COULD OCCUR INCREASING THE BRAKE STOPPING DISTANCE.
Remedy: DEALERS WILL INSPECT THE BRAKE PIPE UNION FOR SIGNS OF BRAKE FLUID, AND IF NECESSARY, INSTALL A NEW BRAKE PIPE UNION.
