2014 Chevrolet Silverado 1500 Brakes

Brake pedal was very hard to press down and was almost no response from brakes, brake assist service came on, vacuum pump failure, ot was replaced.

The brake vacuum pump on the 2014-2018 chevy silverado has intermittent failures causing reduced brakes, which is a major safety issue. Gm has this listed under a "special coverage warrenty" instead of a recall and wont fix this because the warrenty ended 6/24 or 150k miles(mine onpy has 125k). Luckily I didn't have any traffic infront of me and the street light had just turned red and the cross traffic hadn't started to move yet. When I contacted gm about this I talked to 3 different representatives 2 were the initial points of contact, the first stated I would be reimbursed due to this being a safety issue, the second said the first was talking about a "general warrenty"...? The third was a supposed " supervisor who was obviously reading from a script and chose his words very carefully when telling me that because the speciap coverage warrenty was up GM wasn't going to do anything about this which is a leagal way of saying their are ok with this known issue on their trucks out in the world. Probably because it'll be cheaper to have their lawyers fight a lawsuit than to pay for the parts and labor to have this known safety issue fixed.

Driving in Tucumcari New Mexico coming up on a green light that turned from green to yellow to red. I pressed the brake pedal instead of the brakes doing their job in slowing down to come to a stop. The pedal pushed against my pressure a did not allow me to stop or slow down in anyway. Upon this brake failure it made me run the red light an t bone another car in the intersection. This brake failure has cost me my only transportation to work, which is in Reno, Nevada. Now GM has never reached out to speak with me about getting the issue resolved before this accident. Dealership never reached out to me or informed me of any recalls prior to the accident or when I made the purchase in 2024. No warning lights no indicators or on my dash to inform of any problems

When at red lights, or in traffic, when you release the brake pedal to inch farther, and re-apply the brakes they go straight to the floor and you have to basically stand up on the brake pedal to finally stop. The truck slides and makes noises as it comes to stop. I was told these trucks in 2014 have a bad issue with the vacuum pump for the brakes.

Recall 19V-645 / N192268490 was performed on my 2014 Chevy Silverado, prior to me purchasing the vehicle a month ago. A computer adjustment was completed in 2019. The vehicle has brake problems, ie: vehicle will ease forward with brakes applied or while stopped. Upon re-applying brakes I have a HARD brake pedal. Dealer stated that recall was completed and I will have to pay to get vehicle fixed. The problem I am experiencing with this vehicle is the same problem that was addressed in the original recall. Computer adjustment did not fix the problem and a new vacuum pump should be installed on the vehicle. The vehicle was taken to a local GM dealer on 15 September 2025. . If problem is not addressed properly, the vehicle brakes would/could cause an accident, at low speeds or move forward while vehicle is stopped. With vehicle in reverse, braking is harder than in forward causing potential accident.

The brakes feel squishy and it is difficult to stop at low speeds. Yes it is available for inspection upon request. Safety being put at risk by not being able to stop in time possibly causing crash. The truck was taken to a mechanic who found a code stating low vacuum pressure on brake booster but they could not find a leak anywhere and cleared the code. It is unknown if the component has been inspected by the manufacturer. Yes there has been a warning light before. It is unknown when exactly this problem started.

When going at low speeds like through a parking lot when I apply my brakes they get rock hard and do not want to stop. I can get it stopped but just barely. When going at normal driving speed 30mph plus they are fine and stop fine. I almost pulled into a car in a parking lot because I almost couldn't stop due to my brakes failing. This happens every time I go at low speeds 25mph and less

Brake pedal gets hard and brakes become inoperative

Service brake assist activated. Vacuum pump failure, there is no vacuum going to the brake booster from the vacuum pump mounted on the front of the engine block driven by belt pulley.Has code co299-00 brake booster large vacuum leak detected. Pump is not creating vacuum no vacuum going to booster for power brakes.This is a recall.

Was driving through the cities, when all of a sudden the brakes in my vehicle were suddenly not working. Being in heavy traffic doing 40mph, I veered off to the side of the road avoiding an accident. I exited the vehicle and inspected underneath for any broken/leaky brake lines. I then checked to see that I still had brake fluid. Everything seemed to be fine. There was no warning or indication with sound that the brakes were out or going bad. After entering the vehicle again the "service brakes" warning popped up on the dash. I called and had the vehicle taken to a shop. The auto shop stated that the vacuum pump was not working and also recommended to replace the brake booster pipe with the pressure switch.

Trailer Brake driver display notification and alert tone frequently activated with no apparent cause with or without a trailer connected. Alert is so repetitive it becomes an audible and visual distraction to the driver. Manufacturer design restricted code readers at Auto Zone or O’Reilly’s from identifying this problem and force owners to take vehicles to GM shops to identify the cause. The alerts and cause should be repaired under recall at no expense to the owner. I also have video to support.

My brakes do not compress all the way at low RPMs and prevent me from being able to stop. Consistent with other vehicles we called for the same issue on the same year but for some reason my VIN doesn't come up in the recall

Brakes won’t work at low speeds, says online it was a recall at one point just don’t know if my VIN got missed

I was driving with my kids in the truck because i just did school pick up i was aproaching a four way interection when i tried to stop and my break pedal was super stiff and found myself panicked i couldnt stop it almost caused an accident with a tractor trailer truck. I went up and over the curb into vacant parking lot in order to stop.

I have been receiving a service warning for the "Trailer Brake System" for years and found a video online telling me to report it due to this being a GM issue.

Purchased the vehicle yesterday, I had it inspected and the service tech informed me the brake booster was not performing correctly. He said instead of going down as a brake the brake is snapped back to where it is not stopping and it can go completely out to where it will not stop. He informed me of a recall on the brake booster. The local GM Dealer checked for the recall and stated the recall had been fulfilled by the previous owner. There's still a problem with the brake booster.

I started up and was backing out of my driveway. When I tried to slow the brakes felt weird shuddered a lot and then I had difficulty stopping. Service brake assist popped up on my screen. I slowly pulled into the driveway and when I tried to stop the truck shuddered and had a hard time stopping.

About 2 years after purchased (~2016), I was driving slowly in a parking lot and turned into a parking space. The brake pedal became very hard to press and the truck would not stop. I had to push extremely hard to get it to stop. I backed up and experienced the same problem. I put it in park, then the problem went away. There were no warning lights or indicators of a problem. I got a notice for a recall and took it into the dealer for repair in 2019. From 2019 through 2022, I have had 4 to 5 more incidents of the same problem. It seems to repeat when I slow down to a slow crawl with a trailer for added weight. I push the brakes while crawling and then the brake pedal gets hard to push and I loose brakes. Extremely dangerous, especially with added weight on a slight decline. I have found multiple instances with other customers reporting the same problem. Currently in contact with Chevy to resolve. I have reported the problem twice to the dealer and once to the "Customer Satisfaction" hotline. Chevy has confirmed that a recall was performed on the vehicle in 2019, but they cannot provide any information that the recall work fixed the problem or if they even tested that the fix was performed properly. Furthermore, they only report a "reprogramming" was done. No other work reported by Chevy, though, there are comments from other customers that a vacuum pump recall exists. They have yet to resolve the problem.

Brake pedal gets hard under low speeds. Causes a stopping hazzard in parking lots and drive thrust. This year and model has been recalled for this, but my vin is not coming up as a recall. I worry when I back my boat in the water that my truck wont stop.

The warning "Service the Trailer Brake System" continues to randomly alarm. This was "fixed" multiple times. The fix takes about 5 minutes under the dash and then work for a few months to a year before it alarms again. It was "fixed" once during the warranty but it continues to be a problem. This is similar to the reoccurring problems that were recalled on the 2022 Chevrolet Silverados.

Brake pedal went hard almost got into accident in traffic. Took truck to my mechanic vacuum pump was bad. Had to replace pump 350 dollar job.

low speed brake failure and brakes became hard to press.

The trailer Brake system is malfunctioning.

Breaks stop working at slow speed. Vacuum pump fails

Brake vacuum pump is failing creating an unsafe condition while braking when the vehicle is in a low RPM range. I had a close call while backing down a sloping driveway at my home in which it was almost impossible to stop the vehicle. The pedal provided a lot of resistance but the vehicles braking power was greatly reduced. Ultimately I had to use all my strength on the pedal for the vehicle to stop. After continual issues, I am in the process of getting the vehicle repaired. Thank goodness this didn’t occur while backing a boat into the water. I have not been able to use a boat for fear of ending up in the lake.
