Brake pedal became very hard and couldnt hardly stop.

Loss of braking power has occurred multiple times at the boat ramp. While slowly backing down the ramp in reverse, brakes will become stiff and not stop the truck. ABS sensation in the pedal can be felt once pushing the pedal harder until the vehicle stops. Only solution is to put the vehicle in drive and give slight throttle to regain braking power before continuing to back down the ramp (which is less than 20 ft long nonetheless). My tuck has almost not stopped and rolled into the water on a few occasions now.

Started noticing hard brake pedal in reverse and at low speeds until last night it seemed as if my brakes were not there at all pulling into my garage.well this morning I left for work and got maybe 2 miles away and heard a squel and had little to no brake and then they got harder and I got no brakes I almost ran into a lady at a stop light in front of me but swerved and missed her but pulled over off road and noticed that my belt had broke and that vacuum pump had locked up and it needed replaced.

- Emerson, AR, USA

Brake pedal becomes stiff and extremely hard to depress at low speeds (backing out of driveway, stop & go traffic, etc.). vehicle became very difficult to stop and traveled a fair distance even with brake pedal fully engaged. Mileage: 86,000. Appears to be vacuum pump issue per notification letter from GM and as noted by many other drivers with similar experience. Dealership charges $650+ to replace vacuum pump if vehicle is over 72,000 mile limit placed as part of GM's special coverage program.

Brake pedal became very had to depress while reversing at a slow speed. This occurred in my private driveway as I was connecting a trailer. I was not able to stop the vehicle in the usual manner, while a did not collide with the trailer it was within an inch or two before I was able to get the vehicle to stop.

I have had lose or hard braking issues due to a vacuum pump issue. GM sent a letter out in April allowing special coverage but my vehicle doesn't meet there conditions.

- Manchester, NH, USA

The contact owns a 2014 Chevrolet Silverado 1500. While accelerating from a stop, the contact depressed the brake pedal, but the vehicle did not respond. The brake pedal traveled to the floorboard. The dealer was not contacted. The manufacturer was notified of the failure. The vehicle was not diagnosed or repaired. The contact received technical service bulletin number: 10113364 (service brakes, hydraulic), but the vehicle exceeded the maximum mileage. The approximate failure mileage was 79,000.

While driving at low speed the brakes failed to stop and I nearly ran over a lady. Then after parking I went to leave and I almost baked into someone because the brakes again failed. Local dealer said that the vacuum pump is know to just go out randomly. This should be a recall seeing as to how it is sketchy and could get someone killed.

Hard to brake at times at low speed extra effort to brake or may not brake at all. Call Chevrolet customer service and they say someone need a to get hurt in order to make a recall.. when they send me a notification by mail of the problem with my truck.

Hard brake pedal at low speeds. Unable to stop as normal. Happens sometime in forward but most always in reverse.

- Hammond, LA, USA

My wife and I were on vacation and stopped at a rest area off the interstate in Missouri. Upon returning to the vehicle and pulling out of the rest area I applied the brakes and there was no power brake assist. I had to use both feet and push as hard as I could to get the vehicle to stop. Luckily there was a dealership about 10 miles down the interstate that could look at the vehicle. The vacuum pump that supplies vacuum to the power brakes had a complete failure causing no power assist to the bake system. The service technician at the dealership told me that this part must need repair often because they had them in stock. After the repair and $683.36 later we were back on our way.

At very low speeds the brake peddle becomes very hard and will not stop the vehicle. It is very intermittent and once the vehicle is shut off and started again the brakes will perform like normal. It seems to happen while parking or in stop and go traffic.
