I pulled into a drive thru traveling straight ahead. When I tried to brake I heard an odd clicking noise and had a very hard brake pedal. The noise I found out later was the ABS system doing it's job because of my hard braking. I did get the vehicle stopped before hitting the vehicle in front of me. The hard brake continued as I moved through the drive thru line. Once I pulled out on to the road the and tried the brakes again they appeared to work properly. I pulled into an open lot and tried the brakes multiple times at low speed and the hard brake condition continued. My vehicle just turned over 70,000 miles and had the recall N192268490 to recalibrate the brake control module for hard braking on 3/4/2020. It's apparent that the fix GM is doing for the hard brake pedal and stopping is not resolving the issue. This is a very dangerous situation and if I had been carrying any weight or a trailer with my truck I would not have been able to stop. I am going to be replacing the brake vacuum pump which I believe will fix the issue.

My vehicle was serviced on April 14, 2020 for an oil change, tire rotation, etc. And the work was also performed for recall NHTSA campaign number: 19V645000. I had no issues with the braking system prior to this date - no increased pressure, no warning lights, nothing. After this date I noticed my brakes skipping while in reverse on an incline. I live at the top of a hill and my driveway is also a hill, so I didn't think much of it. However, I was reversing out of a slightly inclined parking spot at a local restaurant and pushed the brake pedal all the way to the floorboard and the truck was still not stopping. I managed to use the emergency brake and get the car into drive to avoid hitting a car behind me in the parking lot. Later that same day I when reversing out of another slightly inclined parking spot had to fully use my emergency brake to brake the vehicle because I could not push the brake pedal at all due to so much pressure. I took my truck immediately to the local Chevrolet dealership and was told they could not get to it that day, but that I could drive the vehicle home and bring it back first thing in the morning. I refused to drive my truck off their lot and am appalled that it would even be suggested after hearing that the brakes may or may not work. I called the next day at lunch time after I had not heard anything and was told that there was a short in the brake pump and it would need to be replaced, but the part is on national backorder. I was again told I could come get my truck and drive it until the part came in (because I told them I wasn't paying for their loaner car I'm currently driving that they will try to charge me for). I told the man in the service department he's crazy if he thinks I'm going to come get a truck where the brakes may not work. This is a major safety issue and could cause vehicle damage if not addressed.

The vacuum pump had a complete failure, producing no vacuum pressure to the break assist. The recall suggesting the recalibration of the electronic brake control had been completed months prior. This resulted in similar symptoms, vibration in the break and a hard brake pedal. Once it completely failed, the pedal became extremely stiff and stopping was very difficult. Initially, the pedal vibration was noticed at slower speeds. When the pump failed, the vehicle was in motion on an off ramp coming up to a stop sign. It took almost standing on the break pedal to come to a complete stop. The vehicle has less than 72,000 miles on it.

Driving down the highway, while coming up to traffic and coming to a stop, the brake pedal became rock hard and made it difficult to slow down or stop in time. In an attempt to stop the vehicle from crashing into the rear of the other other vehicles, I swerved to the right to avoid them and side swiped a guardrail.

My truck tends to mimic the 19V761 recall of 2014-2018 Chevrolet Silverado with the 5.3L engine and 3.08 rear axle. However, my vehicle is the 4.3L on occasion, my truck will pull to the left or right unintentionally due to the brakes being used out of my control. I'm particularly lose control of the vehicle every 2-3 seconds while this is happening. The defect also happens more often while traveling above 35 mph and downhill. Most recently during a snow storm in 4WD. The 'episode' usually lasts until I restart the vehicle. If it resolves before I restart it does so viciously, and steering wheel corrects itself while vehicle is moving. I've been to dealership and have been told there's not a recall for VIN number.

Received a recall notice about brakes, stating as the vacuum level drops, the brake assist decreases, increasing braking effort, dealers will reprogram the electronic brake control module, free of charge. I have done this and the problem still exists, especially when driving at slower speeds...I believe replacing the vacuum pump would cure the problem and believe this should be a recall to replace such. Not to just reprogram the computer. I have had numerous close calls and feel this is a very big safety issue and a major concern. Thanks for your time!

Brakes do not work at low speeds. Brake pedal becomes firm/locked and does not allow the pedal to be suppressed. The vehicle continues to roll after driver's maximum power is applied to the brake pedal. The same issue happens in forward and reverse and the vehicle continues to roll with little to no control.
