VEHICLE WAS BEING USE OFF THE ROAD CLIMBING A STEEP BANK. WHEN IT BROKE TRACTION THE DRIVER APPLIED BRAKES AND THE PEDAL WENT TO THE BOTTOM AND WITH NO BRAKING EFFECT. IT HIT A TRUCK FOLLOWING IT DAMAGING THE REAR OF THE TRUCK. THE TRUCK WAS TAKEN TO THE CHEVROLET SERVICE DEPT AND DEEMED TO BE NORMAL. WE TESTED THE TRUCK ON A SIMILAR BANK AND FOUND THE BRAKES FAILED AGAIN UNDER SIMILAR CIRCUMSTANCES. WE THEN TRIED FIVE OTHER CHEVYS (2003 &2004 MODELS) AND FOUND THE SAME BRAKE FAILURE IN ALL FIVE EVERY TIME TRACTION WAS BROKEN. WE HAD REPRESENTATIVES FROM CHEVROLET WITNESS OUR TEST AND ACKNOWLEDGE THERE IS A PROBLEM BUT THEIR TECHNICAL ASSISTANCE SAID THE BRAKES ARE NORMAL. WE CALLED CUSTOMER ASSISTANCE AND DIDN'T GET A DIRECTION FROM THEM. WE ARE WRITING CHEVROLET/GM, BUT DON'T KNOW WHERE OR WHO TO SEND THE COMPLAINT TO. SO FAR WE HAVE HAD NO RESULTS TO CORRECT THIS PROBLEM.

WE HAVE TAKEN SAID VEHICLE TO, TWO DIFFERENT DEALERS, NEITHER COULD FIND PROBLEM AND CONTINUE TO TRY DIFFERENT PARTS. THE VEHICLE HAS A HYDRALIC POWER BOOSTER ON ORDER TO SEE IF THIS R…

THE VEHICLE IS CURRENTLY NOT FIXED, IT IS A CHEVY 2500HD DURAMAX DIESEL. THE VEHICLE HAS AN INTERMITTENT PROBLEM WITH THE BRAKES FAILING TO STOP! WE HAVE TAKEN SAID VEHICLE TO, TWO DIFFERENT DEALERS, NEITHER COULD FIND PROBLEM AND CONTINUE TO TRY DIFFERENT PARTS. THE VEHICLE HAS A HYDRALIC POWER BOOSTER ON ORDER TO SEE IF THIS RECTIFY'S THE PROBLEM. WHEN THE BRAKES FAIL ITS LIKE PUSHING YOUR FOOT ON THE BRAKE AND MEETING FORCE, BY USING EXTREME FORCE ON THE BRAKE PEDAL YOU CAN BYPASS THE FORCE, HOWEVER THIS CAUSES A PANIC STOP.*AK
