Brakes Failed problems of the 2015 GMC Sierra 1500

While going slowly and turning, my brakes failed to stop me. There was no pressure for the brakes. This happened several times. I almost ran into the back of a car.

Backing out of my driveway in reverse applied the brakes and brake went all the way to the floor and did not stop the vehicle like it should. This vehicle had a recall already on it for the vacuum pump failing causing a loss of braking power. I got the recall remedied ( supposedly by increasing the vacuum pressure but now 6 to 7 months later this is a huge issue it is extremely dangerous driving in low speeds down residential areas with kids playing etc and your brakes fail you this ultimately can cause very serious injury if not death. And to know they put a recall out that supposedly fixes the issue and it dosent fix anything makes it worse because your cheap and dont want to replace a vacuum pump is utterly disturbing and disgusting.

Very dangerous situation.

Brake failure due to bad vacuum pump.

Out of no where, I had to use extreme pressure on the pedal to stop the truck. The brakes began to sound rough. I turned the truck on and off hoping that would fix the problem.
