ok the problem is with the brakes, there were four incidents when the brake pedal gets hard and its hard to stop the truck. all four incidents happened backing into my driveway after stepping on the brake pedal 4 to 5 times it would hard. and it would be difficult to stop. The problem is with the brake booster vacuum pump. There was a recall for that exact problem on 2014-2018 silverados. I called the dealership, they told me my VIN # was not one of the listed ones for the recall. the vehicle is available for inspection if requested. the vehicle has not been inspected or confirmed by a dealer. there were no warnings lamps or messagesl. Im certain its the brake booster vacuun pump.

low RPM braking failure. Power assistance fails at low RPM (around 500 - 600) requiring me to apply full body weight to brake pedal to get vehicle to slow and stop. This is a well known and documented problem, but NHTSA won't extend a recall for this issue even when issuing recalls for same problem on other GM trucks, why?

The truck has had its major service to replace all fluids at 70,000 miles. One of the services was a notable vibration and shaking through the steering wheel and on the brakes. Higher the speed the more the vibration. When brakes are applied the vibration gets worse. The vehicles brakes and rotors were checked and good. The mechanic said that the brake pump was slightly loose and it was tightened. It did slightly ease the vibration, but less that a few days later it is back to the same vibrating. The brake power feels weak and when I need to brake I feel like the vehicle is not stopping. I have owner a 2014 Silverado before this and did not have this issue. I took it back to the dealer and they did an alignment which did not help.

My 2016 Chevy Silverado had intermittent hard braking. Especially at slower speeds the brake pedal would get very hard to press and needed a lot of effort to stop. I was especially concerned having newer drivers in my household that the truck was unsafe. I nearly hit others vehicles especially at stoplights and in parking lots. The vehicle was taken to the GM dealer who said it was under recall and completed the repairs. However even though the recall repairs were completed the vehicle still continued to have hard braking issues. It was not resolved until I had the brake vacuum booster pump replaced by a 3rd party as GM was unwilling to complete the repair under the recall

Trailer brake system warning has been flashing non stop for 2 weeks. I do not use or tow anything with this vehicle. Usually it locks up the steering wheel while parking my truck and shuts down the engine. Yesterday I was going 55 on the highway and the warning came on and it shut down the truck tried to put the vehicle in park and rapidly applied the breaks then the truck electrical system came back too and the truck was rolling I pull off to the shoulder to shut the truck off and turn it back on. At the time I had both my sons in the vehicle 4 years old and 9 months. Again usually it always happens when parking my truck (under 5mph) it will lock the steering wheel and totally shut down the trucks engine. Huge safety concern.

Backing up slowly with/without a trailer and have to pump the brakes to stop or stand on the brakes or pumping the brakes and having to use the emergency brake to stop, rev up the engine, put in reverse and have to do the previous steps all over again. This only happens going slowly in reverse. I was told by a mechanic it could be the vacuum pump or TSB on the vacuum pump. No warning messages display. This is a safety risk to myself and others and could cause an accident.

Barking system. it seams like when I-??m in the city the brakes will not engage properly, at some point I-??ve had to use the emergency brake to stop. on the freeway the brakes work good but when running at low rpm it-??s like the brakes go to the floor and the truck is still moving. I went to get my brakes inspected and brake pads are still good, brake fluid was good. They told me to bring it in when the brakes fail again so they could see what was happening. Transmission was replace at 65000 miles because of a faulty torque converter

No brakes at low speed. Problem persists after recall. Needs a vacuum pump. Known problem with Chevrolet and they won-??t replace it.

I was in a drive thru food chain going forward slowly. The brakes seemed hard and I had to really push hard to get the vehicle to stop. I went to a private mechanic who I trust totally. I had the front rotors and all pads replaced due to normal wear. We went on a trip with no braking issues. After returning home and backing down the driveway the brakes seemed hard again and was not stopping the vehicle properly. There were no warning lights on. This only seems to occur at very low speeds and is an alarming when it happens. I have been told by a dealership that there are no recalls on this vehicle. However looking on line I have seen videos and articles about faulty vacuum pumps and braking modules that needed reprogramming that effect braking as I have described. I don't want to take this to a dealership until I know for sure if there is a recall or not. Thanks

My 2016 Chevy Silverado is experiencing the same low speed braking problem that occurs mostly at low speeds like driving in parking lots or stop and go traffic as defined in 19V-645 and N192268490. Driving at these speeds and braking feels like the brakes are completely failing and require excessive force on the brake pedal to stop. What do I do?

I was door dashing then a service alert came on the dash-?? I had pulled over to check what it meant about the trailer brake system. I have never towed or have a trailer to tow around! So continued to drive then my truck cut off then cut on while I was trying to make a turn. Then I pulled over again and luckily a mechanic said it-??s wiring that-??s defected in my truck and I need to get fix! I don-??t have no money to get this fix, is there a way I can get some assistance with this?

I had brakes fixed from recall But they were not properly fixed they gave out on me again barely going 5 miles an hour I hit the back of some one They still are not working properly.

ABS is activated at low speed. Hard pedal and stopping is almost impossible at speeds less than 5 MPH in forward or reverse drive.

- Nortonville , KY, USA

At low speeds, the brake pedal requires much more effort but doesn't engage as quickly as normal driving, so the car still rolls forward even though the brake pedal is fully depressed. This is problematic when parking or at stop signs or stop lights. Plus, it is very dangerous.

When backing out of a parking spot or driving slow breaks almost do not work Will barely stop the the vehicle

- Gainesville, GA, USA

1. The brake vacuum failed. 2. Mine and other drivers safety was put at risk because the vehicle was unable to come to a complete stop even when brake pedal was fully engaged. 3. The problem has been since fixed by a mechanic, before we knew of a previous recall on this particular issue. 4. There were no warnings displayed.
