The contact owns a 2009 Chevrolet Silverado 2500. While driving approximately 50 mph, the brake pedal was depressed, but the brakes failed to operate. The service trailer brakes warning indicator illuminated. The failure recurred several times. The vehicle was taken to the dealer where it was diagnosed that the ABS control module needed to be replaced. The manufacturer was made aware of the failure. The approximate failure mileage was 148,000. The VIN was not available.

Extreme chattering of the rear brakes upon application was observed by the owner/driver, including lock-up of the rear wheels (even though ABS equipped). The vehicle was taken to the autonation Chevrolet superstition springs dealership (6330 E. superstition springs blvd, mesa, Arizona 85206) for inspection and repair (selling dealer). The dealership informed the owner that both rear brake slave cylinders had failed and leaked hydraulic fluid onto the linings. This leakage had caused the sticking of the linings to the brake drums and resulting chattering/lockup of the brakes. Post repair, there have been no further issues in the last 3000 miles of use. The repair was at the expense of the customer. As this occurred at 36094 miles and four years of service in residential use, I consider this a product failure due to some form of manufacturing and/or installation defect with the brake slave cylinders. In 40+ years of automobile ownership of many brands with mileages into the 140K+ range, I have never had a slave cylinder failure, nor have I ever heard of a dual failure. This was the same comment by the service technician at the dealer. Please investigate, or at a minimum, add this to your watch list database. I reviewed the NHTSA's website list of defects, but found nothing regarding this type of incident. The fact that it was a dual component failure and could have resulted in an accident if hard braking had been required by the operator, the manufacturer should be made aware of the issue. I attempted to do so personally, but found the experience unsatisfactory.

Used the vehicle for vacation in 2011 as it was just 1 year old. Very little brake ped left going down hill. Going down hill and step on the brake and there was a bad vibration and growling noise from the brakes. I had it checked and the dealer ground the brake rotors. This never solved the problem, so they replaced the rotors. This solved the problem for the warped rotors for a while. Now the problem started again with 23000 miles and only growls and vibrates when going down hill where you have to step down a little harder. Had it checked out again and they say the rotors are warped again. I replaced the rotors and put new brake pads on and the problem is still there. I do not drive the vehicle hard and only about 4000 miles per year. Whats causing the brake rotors to keep warping.

Driving down highway, check engine light pops up, tractions control indicator light, along with digital display saying several things. Such as, engine reduced power, service traction control soon..........pulled over, had a very rough idle. Made it to parts store and have the truck scanned. Turns out it need the throttle positioning sensor needs replaced. Had them clear the code, drove few more miles and all happens again.

Traveling at about 45 mph with about 3 to 4 car lengths between us, traffic immediately and abruptly stopped. I stomped on the brake pedal only to find it hard and rigid with little response. The truck slowed but would not stop. I rear ended the car in front of me. Resulting in substantial damage to my truck as well as the other car, also a ticket for me. The truck didn't slide, jerk or anything, just gradually slowed till impact. I drive a tractor-trailer that has better braking response.
