2006 Chevrolet Silverado 3500 Brakes Problems

Since repair work was performed on this vehicle in late 2025, it has intermittently experienced sudden, complete brake lockup on all four wheels without any pedal input. This has occurred during sharp turns and during straight, steady highway driving, both suddenly and after gradual buildup; regardless of the pattern leading up to it, the lockup itself is abrupt and unexpected. On March 25, 2026, driving approximately 70 mph on the Glendale Freeway (SR-2) between Mountain Ave and Foothill Blvd, at approximately 39,900 miles, all four brakes suddenly applied with no pedal input, causing the truck to skid toward a stop while traffic continued to pass at highway speed. Smoke was visible from the front wheels and in my mirrors. No crash, fire, injury, or fatality occurred, but the vehicle poses an ongoing risk of sudden, uncommanded loss of control, especially hazardous at highway speed with surrounding traffic. The dealership's inspection found blue thermal discoloration on all four brake rotors, consistent with extreme, sustained overheating, and recommended full brake system replacement estimated at $23,875.25. I am retired, on a fixed income, and cannot readily absorb a repair of this magnitude for an intermittent but serious safety defect. This vehicle uses a Hydro-Boost brake system. GM has published service information (Bulletin PIT3665J) describing a known condition on this platform where the brake pedal can move or self-apply, caused by the internal dump valve failing to seat due to steering system contamination. This bulletin covers Chevrolet Silverado and GMC Sierra trucks across model years 1998-2020, among other GM platforms. Given the severity of this failure and the number of vehicles affected across more than two decades, I believe this warrants review as a potential safety defect.

ANTI-LOCK SENSORS DEVELOP RUST AND FAIL. AT SLOW SPEEDS WHEN YOU APPLY THE BRAKES THEY PULSE AND TAKE EXTRA TIME AND DISTANCE TO STOP

IN THE PROCESS OF EXITING FROM OUR HOME, WHILE TOWING A LARGE BOAT, A BRAKE LINE RUPTURED RELEASING THE BRAKE FLUID AND CAUSING A COMPLETE FAILURE OF THE BRAKE SYSTEM. I INSPECTED THE RUPTURED AREA AND FOUND THAT ALL THE BRAKE LINES WERE SEVERELY RUSTED AND READY TO FAIL AT ANY TIME IN THE NEAR FUTURE. THE VEHICLE WAS TOWED TO A REPAIR FACILITY TO HAVE THE BRAKE LINES REPLACED. ESTIMATED COST IS $950. HAD THIS FAILURE HAPPENED ONE MINUTE LATER THE RESULTS COULD HAVE BEEN CATASTROPHIC! *TR

PARKING BRAKE FAILED TO HOLD TRUCK STATIONARY DURING INSPECTION. WE TRIED TO ADJUST PEDAL FOLLOWING THE GM SERVICE MANUAL AND BRAKE STILL WOULD NOT HOLD. REMOVED REAR BRAKE ROTORS AND FOUND LINING ON SHOES WORN OFF. REPLACED SHOES, HARDWARE, AND ROTOR. CHECKED CABLES AND ACTUATORS FOR SHOES. ASSEMBLED, ADJUSTED AND BURNISHED SHOES AS PER SERVICE MANUAL, BRAKE STILL WOULD NOT HOLD TRUCK ON GRADE INSPECTION WAS CONDUCTED ON. ADJUSTED SHOES UNTIL THEY WERE DRAGGING ON DRUMS AND COULD FINALLY GET BRAKES TO HOLD TRUCK. THE DRAGGING SHOES WILL BE WORN OFF IN A MATTER OF DAYS AND THE BRAKE WILL NOT WORK. OUR COMPANY HAS SEVEN TRUCKS WITH THIS SAME STYLE PARKING BRAKE AND THEY WILL NOT HOLD EVEN AN EMPTY TRUCK DAYS AFTER LEAVING OUR SHOP. I KNOW OF THE RECALL FOR MANUAL TRANSMISSION TRUCKS AND IT SHOULD BE CARRIED OVER TO ALL SILVERADO TRUCKS. *TR

ON MY 2006 SILVERADO 3500, WHEN APPLYING THE BRAKES, AS THE VEHICLE SLOWS TO ABOUT 2-4MPH...THE ABS ACTIVATES AND THE STOPPING FORCE OF THE BRAKES IS REDUCED CAUSING THE VEHICLE TO MISS THE INTENDED STOPPING POINT. I HAVE REPLACED BOTH FRONT HUB BEARINGS WHICH INCLUDES THE FRONT SENSORS AS OTHERS HAVE REPORTED THIS CURES THE PROBLEM YET THE PROBLEM PERSISTS. THERE ARE 80,000 MILES ON THE VEHICLE, I HAVE OWNED SINCE NEW, THERE HAVE BEEN NO ACCIDENTS OR ABUSE. THERE ARE NO CHECK ENGINE LIGHTS, ABS LIGHTS OR ANYTHING INDICATING A FAULT. ON THE INTERNET, THERE ARE MANY COMPLAINTS JUST AS MINE. THESE VEHICLES ARE A PUBLIC SAFETY CONCERN BECAUSE THERE IS OBVIOUSLY AN ACKNOWLEDGE PROBLEM DUE TO A RECALL OF PREVIOUS YEARS THAT USE THE SAME TECHNOLOGY. I FEEL THE MANUFACTURER NEEDS TO COME UP WITH A REMEDY FOR THIS DEFECT IN DESIGN. *TR
