2005 Chevrolet Avalanche 1500 Brakes Problems

“So the hydraboost is failing and my truck is pouring an insane amount of power steering fluid from hydraboost system. When researching this problem for my year make and model the hydraboost recall pops up but when calling Chevrolet they want to do nothing. When its apparent my truck is affected by trash parts. It only has 149000 miles on it and the hydraboost system is gone. I'm tired of adding 2 quarts of power steering fluid a week, and cant even drive my family around because I waiting on brakes to sporadically fail due to the system being compromised.”

“I was driving to work 12/17/16, 5:40am. I was traveling to work and I lost all pressure in my pedal. Which LED me to nearly hit a telephone pole. The master cylinder and a flex brake line going from the master cylinder to the brake booster(module) were replaced. But this did not fix the problem. I have bench bled the master cylinder, and all brake lines around the truck. I still have no brakes unless you push them to the floor. I have done some research, and found were other people with the same model and year truck have had the same problem. …”

“Brakes failed under hard stop (highway, in motion). Intermediate steel brake line failed to rear brakes in a mode of rupture due to corrosion. Abs light had been on with service brake message as well. All other steel lines were corroded and contacted GM. 2 other silverado line vehicles owned also failed this year due to corrosion. Gm response was that no recall existed. Replaced all steel brake lines in vehicle with stainless aftermarket lines. After multiple contacts with GM customer service, I was told to save my receipts for repairs. …”

“I was slowing down for a stop light. An animal ran in front of me. I stepped hard on the brakes. The brake pedal went to the floor. No prior problems. I had the truck towed to an independent mechanic. The mechanic found the right front steel brake line ruptured. Upon further testing, the left front steel brake line also ruptured. Both lines were rusty. The lines did not appear to be coated. New brake lines from napa had a coating. When the front brakes failed to function, the rear brakes did very little to stop the vehicle. …”

“Stepped on the brakes to stop for a stop sign at a major intersection and my brake pedal was good a first then completely sunk to the floor. The truck stopped in the middle of the intersection that was thankfully void of traffic. My wife and I were a bit shook up. It could easily been worse. We carefully traveled to the nearest service station and were lucky to get flatbedded to a local Chevrolet dealer. Memorial day 4pm in georgia, I did not have high hopes. The service people examined the truck and it was apparent that my truck had catastrophic failure of the brake lines. …”
