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.

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 different times when attempting to park the truck, the brake pedal becomes very stiff (hard). I had to apply both feet to the brake pedal to stop the truck. This occurred twice in the past month. Contacted GM and was told that there is no recalls on this issue. I checked the internet and discovered that other Silverado and Sierra owners are having the same problem. There needs to be a recall before someone is injured or dies because of this issue! in both cases I was driving at low speeds and in the process of parking the truck in my driveway and at home depot.
