At low speeds the brake pedal intermittently gets hard and makes it difficult to stop. It seems like there is no power brakes. Usually happens when parking. This has happened about 5 times.

Silverado 1500

  • 56,000 miles
Brake vacuum pump failed while on the freeway causing brake pedal to be unresponsive almost causing major accident. This is listed as under investigation. There was no warning or light. Brake pedal instantly became stiff and could not be pressed down. Chevrolet fixed this by replacing only the pump. It's recommended the vacuum lines and brake booster be replaced too due to potential oil leakage which states will cause pump to fail again. Chevy did not replace additional parts for me.

When travelling at low speeds, the brake pedal pushes all the way to the floor and does not fully stop the vehicle. On 3 occasions now, I have had problems stopping the truck while parking, coming very close to hitting another vehicle.

  • 62,000 miles
The contact owns a 2015 Chevrolet Silverado 1500. While reversing out of the parking lot, the contact attempted to depress the brake pedal; however, they failed to respond. When the contact made a second attempt, the brakes responded and the vehicle stopped. There were no warning indicators illuminated. The contact took the vehicle to an independent mechanic where it was diagnosed that the brake vacuum failed and needed to be replaced. The vehicle was repaired, but the failure recurred. The dealer and manufacturer were not notified. The failure mileage was 62,000. The VIN was not provided.

Silverado 1500

  • 41,000 miles
When coming to a stop in traffic the brakes failed to stop my truck. I was going straight at a very low speed. The pedal felt like I was pushing on a brick. I did get my truck stopped and got it off the road. I called my dealer who said they had not heard of this problem but thought it sounded like a brake booster failure. I called GM customer service who started a case # 9-5055710889, they told me that the truck was out of warrenty. Upon further reading I discovered the tsb for my truck to replace the brake booster, master cylinder, line, and vacum pump. The truck is being repaired now. My truck has 41,000 miles on it.

problem #130

Feb 142019

Silverado 1500

  • 50,000 miles
My truck brakes normally except when I stopped, then at low speed the truck fails to stop. I've almost gotten into multiple accidents (hitting walls, poles, a bus) and its even worse going downhill. It takes both feet and all my weight to get the truck to stop. Eventually someone is going to get into a bad accident because of this issue. Happens when going forward and reverse. I've read several articles about it on the internet and I've talked with GM techs and it's a bad problem with the vacuum pump. Please help!!!!

When slowing down to park, I lost braking and could not stop the truck. I had to put the truck in park to stop the momentum. This happened going in reverse. When taken to dealer I was charged $470.96 for parts and labor at N the vacuum pump which provides power for braking and steering.

problem #127

Silverado 1500

  • 63,500 miles
Vacuum pump on 2015 Chevrolet Silverado 1500 went out while driving on highway on July 8, 2018. Applied brakes and they were hard and would not depress. They eventually started to work so I was able to stop. This occurred off and on for over two weeks, usually at slower speeds, until I was able to get them fixed on July 24, 2018. See repair order. I wanted to file this because I saw the NHTSA was investigating faulty brake vacuum pumps and mine was not repaired at a Chevrolet dealer.

Silverado 1500

  • 52,000 miles
My truck would brake normally except when I stopped, then at low speed the truck would fail to stop. I almost got into multiple accidents (hitting walls, poles, a bus) and was even worse going downhill. It took both feet and all my weight to get the truck to stop. My dealer said the vacuum pump was at 11psi when it should have been 27. Eventually someone is going to get into a bad accident because of this issue.

  • 27,000 miles
Vacuum pump. My vacuum pump went out as I was driving home on the highway. Every few presses of the brake pedal it would go all the way to the floor and it took much longer to stop. It was scary and I am very thankful I didn't get in a wreck. I got it fixed at my Chevrolet dealer. The cost for repair was $600. Worst part is my vehicle, a 2015, ony had 27,000 miles on it. Still feels new and the brakes failed.

On several occasions while backing down a sloped driveway while depressing the brake, the pedal has become hard to push and braking was almost impossible. This same problem has occurred while backing a trailer, it takes a greater applied force to depress the brake.

problem #123

Silverado 1500

  • 65,000 miles
I had a brake defective vacuum pump on my on 2015 Chevrolet Silverado 1500. I had the vacuum pump changed on 1/30/2019. My brakes were losing pressure when I was driving slowly. My brakes would lose pressure primarily while I was backing up. I have narrowly missed having several accidents (with other vehicles and property) due to the problem. On one instance, I lost brake pressure going down a hill. Braking distance was increased, and so were my efforts to halt my truck. I also noticed my brakes losing pressure after my truck giving me several alerts (while driving and parked) about servicing the trailer brake system. I am not sure if that has any bearing on the vacuum pump. I will also be replacing the trailer brake switch on my truck. I hope this fixes everything and I will not have that problem again. I did some research on the internet and it sounds like this is a common problem. This has been a particular problem with my truck since about August or so.

problem #122

Silverado 1500

  • 49,000 miles
As my wife came to a complete stop at a stoplight and as the light turned green, she pressed the gas pedal and the truck would not accerlate. She pressed the gas pedal down to the floor board and still would not accerlate. So due to this the truck slowly rolled foward. She slammed on the brakes and the brakes would not move. Like if they became locked and wouldn't move an inch. At this point she is trying to get off the road to the shoulder, to avoid oncoming traffic. Then she finds that the steering wheel is also locked and can not be turned. It's taking her maximum effort to stop the truck from rolling forward and to veer off the road to avoid other vehicles. She is finally able to stop the vehicle after about 100 yards of effort and waits about 10 minutes, before the brakes and steering wheel would free up. No error message was present the entire time these functions were disabled and after they freed up, it was like if nothing ever happened. No check engine light has ever been on this vehicle. Strong belief this is a manufacturing defect and should have a recall.

Brake pedal becomes hard to press when frequently stopping, such as backing up a trailer or in stop & go traffic. This has nearly caused me to have an accident more than once. It is becoming progressively worse and more frequent there are no fault indicators or codes displayed. It will start working again and then start randomly in traffic.

When having to apply the brakes repeatedly, slow traffic, stop lights, backing a trailer. The brakes become extremely hard to push and do not function. Exceptionally dangerous backing a trailer down a boat ramp or in stop and go traffice. This has happened numerous times over the past year

Silverado 1500

  • 43,362 miles
When traveling in stop and go traffic, the brake pedal gets very hard and you can not stop the vehicle. This happened to me 3 times too many, I had the vehicle towed to the dealership, $709 later, they supposedly replaced the vacuum pump. Dealer stated they have had other vehicles brought in for the same reason. This is a serious problem.
