Going from 40 to 5mph breaks feel like is locking for couple of second and back to normal, any speed before stops truck has a little hesitation before breaking.

Manufacturer recall numbern192268490 NHTSA recall number19V645 on August 14, 2014, I was driving the 2017 Chevy Silverado 4X4 work truck on a rural state route in holmes county, Ohio. I had pulled off on the side of the road to pick up my traffic counting equipment. Once I was finished, I pulled into a driveway to turn around. I began to back out of the drive when the brake pedal went rock hard, I lost all pedal and had no brakes. I hit the guardrail that was directly behind me when I couldn't stop. No damage to the guardrail, but plenty of damage to my truck. Obviously, I didn't think this was right so the very next day I took the truck to progressive Chevrolet. After techs had a chance to look over the vehicle, they said the vacuum pump was defective and it was replaced at no cost to me. That's all well and good, but had the vacuum pump not failed, I would not have hit the guardrail.

I was in an accident on Thursday, August 22 where I slammed into the back of another vehicle on the road. I had at least 40 feet to stop and I literally stood on teh brakes and truck barely slowed down and before colliding with the other vehicle. I received a letter from GM a few months ago saying the brake assist pump may be faulty and that I could get it replaced even though if it were to fail the truck would still brake within "standard". I didnt think anything of it since it wasn't described as an emergency and I thought I would have ti taken care of the next time I took the truck in for service. My wife had commented on my brakes feeling spongy. After the wreck I was so disturbed by how poorly the truck responded to forcibly depressing the brakes pedal that I started researching and I found where NHTSA was investigating this very issue in the 2014-16 Silverado and I feel strongly that my issue should be included in this investigation. The truck should have stopped and I think a recall should be issued. The brakes do no operate within "standard" when the brake assist pump stops working.

At low engine RPM the brake force becomes extremely excessive. While backing down a long boat ramp last week this occurred and my wife could not press hard enough to stop the vehicle resulting in a collision to avoid the vehicle going into the water. I contacted Chevrolet and was told there was no recall on this vehicle.

The vehicle in motion, at low speeds (under 10 mph), the brakes fail to slow or stop the vehicle until the brake pedal is fully depressed which unexpectedly requires more effort than braking under normal conditions. Even with the pedal fully depressed, it still does not stop the vehicle within the expected stopping range.

I was pulling into wal-mart in white settlement, went to brake to slow down and it felt like the pressure was completely gone causing me to brake harder to stop.

This morning at low speed stop and go traffic and again when low speed parking the black pedal became hard to push and car would not stop properly. Happened both directions while parking. Will take to the dealer this afternoon. Seems to brake fine at higher speeds and slowing from higher speeds. Scary
