Truck was driven into the ditch to avoid rear-ending vehicles. This happened immediately without warning, all braking prior to this incident was normal. When taken to our mechanic, they advised the brake lines underneath were notorious for rusting out and failing, new stainless steel lines were then installed to correct the problem.

I bought a 2003 chevy silverado 2500hd 15 years ago and gave it to my 16 year old son. Recently we noticed that the brakes and steering was acting funny and making a noise, so we replaced the power steering pump and hoses. The problem only started getting worse. I did some research and found an old recall or notice related to the hydro-boost relief valve that was defected because of o-ring failure. Just searching the vehicle will show several sites revealing the problem. The nada site goes into more detail on the problem. We have parked the truck until a decision is made. I contacted the manufacture and they stated that there was no problem, the vehicle has trouble when steering and looses braking.

Brake line failure in several places. Was under vehicle performing an oil change. Noticed fluid on the bottom of the fuel tank. Investigated and found the rear most hard brake line leaking. Continued to inspect all hard lines and found several areas where leaks were present. Removed vehicle from use and started replacing all hard brake lines. New lines are stainless steel thus I should never run into this issue again. Gm should have used stainless steel lines in the first place rather than plain steel lines. The original brakes lines broke like twigs when I bent them to throw them away. I have never seen brake lines in this type of condition on a vehicle with 130,000 miles. This is a safety hazard and possible accident waiting to happen. I have never experienced brake line failure on a vehicle like the chevy silverado. The federal safety agency needs to force gm to perform a recall and resolve this issue.
