Brake Disc Pads problems of the 2014 Chevrolet Silverado 1500

While driving my 2014 Silverado 1500 truck at slow speeds (under 20 mph), in three different parking lots with pedestrians present, the brakes did not respond to any level of foot pressure. These failures happened over a 30-minute span. The truck kept moving forward even though I was pulling on the steering wheel to help with depressing the brake pedal with as much force as I could. I had to put the transmission into neutral to help stop the vehicle. Upon reviewing internet blogs of this issue I found others here on NHTSA with the same problem and also found gm/chevy had technical service bulletins published for this issue: pit5361d & pit5362b. What failed was the power brake vacuum pump/booster which provides the vacuum for the brakes to function. I had the truck towed to my chevy dealer for repair. This brake vacuum pump/booster repair cost me $1,100. 00 as they said it was not covered under warranty nor was a recall at this point. I find it hard to believe that with so many others affected, myself included, with this major safety issue that it is not yet a full recall item. Fact is, you cannot drive a vehicle without working brakes, period. It is not a situation such as brake pads being worn (they are not), it is the core functionality of the power brake system that failed and should be under a major recall. Here are the parts that were repaired/replaced: brake vacuum pump, vacuum pump belt, a/c belt, and pipe from pump to the booster. Please escalate this complaint as this part failure in chevy trucks, as well as gm and Cadillac as seen from other's posts, is a life and death issue when operating a vehicle with brake systems failure such as this specific issue.

Any time, while I am driving, the brakes turn rock hard when trying to brake. When it first started a little over a week ago, the brakes would only turn hard when I was going 20mph or slower. Now it's everytime I try to brake while driving. Every once in awhile it will happen when I am stationary. When it first happened a little over a week ago I almost hit another vehicle in front of me while I was coming to a stop light. It took everything I had in me to stop my vehicle due to the brakes. My husband, who is a mechanic, looked at my brake pads and they are fine. I keep having the service brake assist badge pop up on my dash when I have trouble braking. There needs to be a recall on this to fix the vacuum pump, brake booster, or whatever maybe causing the issue. This happens now everytime I'm driving on the highway, country road, my driveway, or turning. I have completely stopped driving my truck until the issue is fixed, due to it being a safety hazard for my family and others. I have horses so I use my truck on a daily occurrence to take care of their needs. The problem needs to be fixed and a recall needs to happen.

Brakes on my truck have failed at low speed while parking. After only 3-4 times of lightly pumping the brakes they completely go hard and the peddle will not move. No matter what amount of pressure is applied the truck will not stop. Seems to happen when in reverse the most. Brake pads, fluids, etc are all perfect. Problem doesn't happen at all when driving at speed. Only occurred at low speed. Dealership says that's probably the vacuum failing. . . Have found that there are hundreds of complains describing the exact same problem on trucks.

Twice in the last three days the brakes on my truck have failed at low speed while parking. After only 3-4 times of lightly pumping the brakes they completely go hard and the peddle will not move. No matter what amount of pressure is applied the truck will not stop. Seems to happen when in reverse the most. Brake pads, fluids, etc are all perfect. Problem doesn't happen at all when driving at speed. Only occurred at low speed. Dealership says that's probably the vacuum failing. . . Have found that there are hundreds of complains describing the exact same problem on trucks with less than 50,000 miles on average.

I've noticed multiple times when backing up at slow speeds such as backing into a parking space that the brakes are very weak. I've had to apply very hard pressure to the brake peddle to stop and very nearly hit a light pole once. It seems to happen more often in humid or rainy weather. I've had the brakes checked, pads and rotors checked out fine. I also spoke with another silverado owner who noticed the same issue.
