When braking at slow speeds, like when idling in traffic or rolling through a parking lot, when the brake pedal is depressed it is very hard, like when pressing the brake pedal with the vehicles engine off.

My 2014 gmc sierra is having a major brake issue. I replaced the brake pads after being told the padding was low. This did not fix the problem. My truck does not slow down when braking on a hill. I read in another article that the vacuum pump goes out at a low rpm, causing the truck not to stop. Unfortunately, my wife was driving my truck down the driveway, and couldn't stop. This issue almost caused her to hit…

First noticed at about 65000 miles. When braking in stop-and-go traffic or in reverse (especially down an incline such as a boat ramp), the brakes can become very hard to press and non-responsive. This results in long stopping distances. Had the truck inspected by dealer and they suggested vacuum pump. After researching this issue, there appears to be a general issue with the vacuum pumps that gm will replace under…

This occurrence happened in the spring of 2018. I had exited the highway after a [redacted] and sat in a long line to enter a ballpark. The wait in this slow moving line may have been a half hour. In this half hour, i would let off the brake to roll forward and reapply the brake. It was mostly down hill so the gas pedal was unnecessary. When we payed for parking, we were asked to pull over to the side of the road,…

There have been numerous complaints to the dealerships and on gm forums. This problem needs to be addressed. I'm glad…
