This brake issue is a huge safety issue. With multiple complaints I don't understand why GM hasn't made this a recall yet. On more than one occasion my brakes have stiffened up and stopped working. One time was at a stop sign and I had to drive in the ditch to avoid hitting the vehicle in front of me. Another time was in reverse backing out of a parking spot and I nearly hit a parked truck. This is obviously a manufacturer defect that needs to be addressed. GM, what the heck are you waiting for?
In stop and go traffic or in a parking lot if you are on and off the breaks in a short period of time the break petal will get hard and the breaks go out. Ive brought this up to Chevrolet corporate and they are already aware of the problem but said I would have to pay out of my own pocket. I feel that this is a saftey concern and that they should have to stand behind their product
I've noticed multiple times when backing up at slow speeds such as backing into a parking space that the brakes are very weak. I've had to apply very hard pressure to the brake peddle to stop and very nearly hit a light pole once. It seems to happen more often in humid or rainy weather. I've had the brakes checked, pads and rotors checked out fine. I also spoke with another Silverado owner who noticed the same issue.
My brake assist light kept coming on, and when I would be going at a low speed and applying the brake, the brake peddle would get very hard and stiff. I would have to apply all possible weight I can in order to get the vehicle to stop. I was informed today that a vacuum pump is causing this issue, and needs to be replaced. The dealership told me that this is becoming a common problem that they are seeing. This is very dangerous, as I could have easily hit somebody, or been unable to stop when backing into my garage. If it had been my wife driving, I don't know if she would have been able to get it stopped with how hard I was having to press the brakes repeatedly. This happened while in a parking lot in motion, and also while backing into my garage
After driving for any amount of time at a highway speed, the brake pedal is extremely hard to push and the vehicle will continue to roll for several feet at slow speeds, usually under 10 mph. For example, when coming to a stop light or trying to park in a parking lot. Very unsafe. I backed into a concrete wall, luckily did not damage my truck. After research, many people have stated it is a defective vacuum pump. Poor performance by GM, not to mention the lack of customer service or backing of the bad parts they are putting in vehicles. Brakes not working in a vehicle due to a faulty part is unsafe. I'm havjng trouble having GM even admitting it's a problem, and I hope I don't injure or kill myself or somebody else because of this issue. 71000 miles

I have a 2014 Silverado with 60K miles. On Sunday, I was pulling into the garage after a short errand and I lost most of the braking power. I was able to stop the truck by pressing the brake pedal hard. I immediately drove backwards and it did the same thing. I restarted the vehicle the issue went away, mind you during all of this the ABS light never came on either. Searching online I found a bulletin in some rare situations, a customer may comment on a hard brake pedal or that increased effort is needed to depress the brake pedal. While performing normal diagnostics, fluid may be found in the brake booster and/or the booster vacuum line. If engine oil is found, it is important the following parts are replaced. If not, the condition will return. 1. vacuum pump 2. vacuum line between the booster and the pump 3. brake booster 4. master cylinder after finding this and reading all the accounts I feel like GM needs to make this a special coverage. This is 100% safety concern
I was pulling into work and brake peddle got stiff then no brakes I was baking into parking spot and concrete wall stopped the truck I took it straight to the dealer and they said vacuum pump and brake booster needed to be replaced a service bulletin was out for it but was not under warranty and it would cost $1000 dollars to fix it 68,000 miles on the truck this happens at 15 mph if someone would have been in front of me it could have killed them
When in reverse and applying the brake, brake pedal is so hard to push and will not stop vehicle. Only happens in reverse. Doesn't matter if on incline or on flat. Brake pedal cannot be pushed and vehicle still moving in reverse position.
At low speeds in bumper to bumper traffic the brake pedal was extremely hard with maybe a 1/4" of travel. The truck barely stopped had to use the E-brake to assist the vehical to stop. Made it over to the shoulder of the freeway. Turned the vehical off. Got out checked the brakes visually. Everything seemed ok. I started the vehical up and with caution tried moving the vehical and every thing was back to normal. Three weeks later it did the same thing parking along the curb in front of my house.
My brake pedal just got hard. It took was all I could do to stop my truck, thank goodness I was in a 35 mph zone and not at highway speeds. I was on vac and went to local dealer to see what happened. My brake vacuum pump failed & it cost me $504 to repair
When applying brake with motor at idle or close to it. The brake pedal will get hard. I checked vacuum from the separate vacuum pump and only had 9 in hg. It will build and store some vacuum but will also fade as it idles. I replaced the pump and I now have 26 in hg and when parking or doing short maneuvers all is good. I have replaced the pump at a price of $135 and did the work myself.
I attempted to stop the vehicle at a low speed and when I applied the brakes, the brake pedal was rock hard. The truck did not want to stop and took a considerable amount of force on the pedal to get the truck to stop.
Many times the brake pedal is hard when depressed and stopping is very slow. Most times it has happened at low speed when approaching stop lights or parking. One time was at over 65mph. Have been to 2 dealers and neither can get the issue to repeat or get a code to diagnose. Problem happened first at 40K miles and continues now at 60K miles.
Driving 70 miles an hour on the toll road in a booster pump went out and no breaks had to stop manually fortunately there were no cars in front of me I replacing the booster pump the dealer will not respond there advice was for me to buy an extended warranty. 40,000 miles on the truck I bought it in 2015 December a demo at 5000 miles on it and it now has 40,000 miles.this is a very serious problem my uses the truck to commute too work daily had she been driving she would have wrecked the truck
Per attached work orders, my brakes were going to the floor in reverse only. They replaced master cylinder and said all fixed. Several weeks later happened again so now replaced vacuum & booster pump. That was 2 weeks ago. Still working and filed complaint with GM but they said nothing they could do. These have no moving or mechanical parts and should probably never wear out. Prior to all this I was getting a report to service electronic trailer brakes but had not hooked up a trailer? when first pointed this out they said could not find anything. Second time they replaced electronic switch as "bad". personally I feel it had nothing to do with all the parts replaced and feel strongly that this is electronic and related to the ABS braking system electronics or mother board. Vehicle was in reverse moving slowly. Damaged rear bumper last fail due to unable to stop vehicle. If someone was behind me directing me there is a good chance they could have been crushed or injured seriously. I feel this is a recall waiting to happen.
The contact owns a 2014 Chevrolet Silverado 1500. The contact stated that the vehicle experienced a loss of power. Also, the ABS and stabilitrak warning indicators illuminated. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. Eddy's Chevrolet Cadillac (8801 E kellogg dr, wichita, ks) diagnosed that the battery was defective and needed to be replaced. The vehicle was repaired, but the failure recurred. The contact received notification of the vehicle being involved in a tsb. The vehicle was taken to davis-moore Chevrolet (8200 w kellogg dr, wichita, ks) where a software update was performed; however, the failure recurred on six occasions. The manufacturer was not made aware of the issue. The failure mileage was 54,000.
The truck turned off on me on the freeway and I lost control for a few seconds. Had to pay to get it towed to my house because it was at night couldn't take it to the dealer. Took it to the dealer after and they said it was my battery. I'm just getting tired of all the issues that GM has. I'm getting frustrated of taking my truck in for recalls every other month! can some one help I'm trying to get my money back.
While driving my 2014 Silverado my brakes became hard to use. I had to push hard with both get to get them to work. Then I drove the rest of the way and they where fine until I tried to park and it happened again. I found on a forum that this is a vaccume pump issue that is common in this year.
