Brake pedal always harder than normal brakes. Gets worse at low speeds to the point of having little to no breaks at all

- Loranger, LA, USA

My Silverado has already had the software upgrade related to the previous vacuum pump/brake recall (N192268490). It initially helped, but now the brake pedal is again extremely hard to press at slow speeds, such as in traffic. You need to almost stand on it to stop. It appears that the deterioration is back where it was before the software "fix." I will be taking to the dealership this week and requesting a replacement of the vacuum pump under warranty or recall. I am beyond regular powertrain warranty at this point, but brakes seem like they should work past 80K.

At low speeds, applying the brake causes the pedal to become stiff and lock up and not work

When driving at a low speed while parking or in traffic, my brake pedal either gets very hard or very soft and feels as if though I have no braking power. It feels like they are trying to brake but don't have enough force to stop the vehicle. This has happened on numerous occasions, I have almost hit cars in traffic or cars in parking lots while parking because the brakes can not be fully engaged. I have replaced all my brakes and rotors and have had everything inspected and have been told it may be the vaccum pump on a car that has only 56K miles. This is a very serious safety concern that the dealer is refusing to recognize as faulty. I have had to use my parking brake just to get home. Now my car sits because it is unsafe to drive and the dealer quoted over 1700 to fix.

After a 300 mile drive the brakes all but failed when attempting to back into a parking spot. The pedal was stiff feeling and required significant pressure to stop. Going forward seemed to be normal then when I backed up again it was bad. This has occurred a few times now. The latest was just before christmas, waiting in line for a drive thru pickup and after 20 mins when we moved forward the vehicle was very difficult to stop.

If I am at a stop and creep up and push the brake pedal, it gets solid and fails to stop the vehicle!

Loss of brakes when driving slow

- Bend, OR, USA

Breaks will not catch. As I'm driving and trying to stop the truck will keep rolling. This is even when driving slow. The break pedal is hard. And will not stop. I took truck in for a recall on the break system but the light sensor is still on and breaks will not catch. This is going forward backward parked or going to light. Has been happening off and on for a month.

Breaks stop working at low speeds. Stop and go traffic, parking, stopping for people, stop signs, traffic lights. Breaks go down half way then get hard to push.

Break system failing. It happens time to time when at slow speeds. Mostly when trying to slow vehicle ot a stop at a low speed. Requires bodyweight pressure to stop the vehicle. It still feels like its slipping to a stop. This is happens when in reverse and forward.

When driving truck on a busy road the warning sign of (service stabilitrak) pops up on dashboard and lights would flicker turning on and off as the truck would also seem to turn off and quickly back on regaining electric power. When reversing it started locking the steering wheel and the (service stabilitrak) warning sign would pop up. Truck was taken to dealership twice for recalls and they said problem was corrected and now it's there for the third time as we speak. When I parked in my driveway I was able to record the incident and video was sent to dealership mechanic. Last Sunday as I headed out to buy dinner, my vehicle seemed to be running fine. I noticed the dashboard lights flickered twice and that was it. When I was approximately 25 miles from my residence (service stabilitrak) warning popped on dashboard and truck completely turned off locking my brakes loosing complete control of the vehicle and it went on its own into a busy intersection going downhill. Steering wheel and brake was locked loosing all electrical and driving control. It would not turn, it would not do any changes. My truck ended up bumping into a sidewalk, I was terrified as I almost lost my life. Shaking in fear I tried to restart my truck and it did turn on. I went inside the shopping center parking lot, parked and called aaa so my vehicle could be towed to our nearest dealership. We had an appointment at the dealership for Tuesday due to negative reviews and they were going to look at our vehicle again. However, I never expected that I would almost loose my life. It's the third time it's been seen and I fear it will be the same scenario. I cannot put my family's life at risk. The truck is currently at the dealership being serviced. I will not be driving this vehicle unless I have been given proof that they fixed the issue. I have documentation for proof.

I was going through a drive through restaurant, stopping and starting with cars in front of me. When I tried to stop the brake pedal became very hard to push and vehicle didn't want to stop. I shut off the vehicle and restarted. The brakes reverted back to normal. Had I not been going moving slowly this default would have caused an accident.

Powered brake vacuum pump occasionally fails at lower RPM

- Midlothian, TX, USA

Breaking at low speed in traffic or a parking lot the breaks grab, skip and the truck vibrates before coming to a stop. Returned truck to glendora Chevrolet where purchased. They performed recall N192268490, updated ebcm, wcc:28yn28468172 per receipt they gave me. Vacuum pump was replaced. All this did not correct the break problem to this day. Please advise.

When I step on the brakes it gets really hard and will not stop. It happened to me in a parking lot. I was pulling into a parking spot and did not stop. Then when I was driving down the road I rear-ended someone and I was not driving very fast. My concern is that if a child or car runs out in front of me I wil not be able to stop. This has happened several times now. I have paid mechanics to replace my brake pads, calipers, disc's because I do not want to hurt myself or someone else.
