I almost ran into another car because the other driver stopped suddenly and I had to pump the brakes over and over to stop when the rusted line broke. I was on a city street driving speed limit and was lucky to be able to stop. I was towing my trailer last week and almost lost the trailer because the entire underbody is rusted. I have had several trucks and never have seen this happen. It was a scary situation in both cases.

Brake line ruptured leading to complete loss of braking. Hit car in front of me as it came to a stop. This is the second time that the brakes have failed due to brake line rupture due to excessive corrosion of the brake line metal. Please force GM to issue a recall.

Three weeks ago noticed low brake fluid. Filled reservoir and didn't see and leaks. Yesterday I was in town shopping and when I came out of store and leaving brake peddle went to floor when I tried to stop had enough brake to stop before hitting car in front of me. Bought a quart of fluid and refilled tank and cautiously made it the 25 miles home after refilling twice. Looked under truck and saw leak above the fuel filter. The whole line under truck is terribly corroded and will need replacing. I live in Hawaii and have had the truck for 5 years so no salt damage here.

Brakes failed due to rupture of rusted brake line, no warning light while driving on the interstate. Was barely able to stop by pressing brake pedal to the floor. ABS did not activate. Took vehicle to mechanic. Multiple brake lines rusted out.
