I came up to an intersection, pressed my brakes, and they were hard to press causing me to run the red light and almost hit another vehicle. Even if a part fails, this should not be an outcome. Brake petal so hard you can't get the vehicle stopped.

Breaks do not work at low speed in reverse, break pedal goes all the way to the floor and excessive pressure must be applied in order to stop vehicle, this is extremely unsafe due to low visibility when backing the vehicle.

At slow speeds and brake pedal requires immense force (~200lbs) to press and engage brakes. Significant grinding can be felt in the pedal. This often requires emergency brake usage to stop. Condition is intermittent. Occasionally happens in reverse occasionally forward with wheel turned or without.

Brake pedal randomly requires significantly higher pressure to slow/stop the vehicle, particularly at slow speeds. Has happened 2-3 times over the past year and this week is occurring more frequently; even daily.

While backing slowly on a boat launch ramp, petal was depressed all the way and the tow vehicle did not stop immediately. Felt as though the petal was to the floor, vehicle rolled up to several feet before stopping. Towing roughly 6800 lb. Which is within specification limit for this specific vehicle.

All happened same day. Was 8 hours from home and pulling into parking spot and the brakes went to the floor 3 times. Has not occurred since. But when that happened the air started blowing warm and the service driver assist came on briefly. Still air is blowing warm and the service driver assist comes on. Have never had a check engine light come on. I am having it checked out this week.

The vacuum assist pump on my 2014 gmc sierra went out suddenly during my morning commute. The brake pedal became very firm and the brakes were unresponsive. If i had been driving in an congested area an accident would likely occur.

Brought it to gmc beaman in nashville, tn and saw [xxx] (service advisor for beaman automotive). They reported they were not…

On two separate occasions, each at the end of a two hour drive, i was pulling into a parking space and lost all power to my brakes. They did not depress to the floor, they seemed to almost push back. At that point i pushed harder and the brake pushed to the floor. In both instances i almost hit the parked cars next to me. Due to not having proper braking i had to back up and pull back in, brakes continued to do the…
