Sierra 1500 8-cyl

  • 177,000 miles


While driving forward in traffic when car cut in front from the next lane to the right. This required emergency braking, but my speed was slow and truck should have stopped within the space available and the truck brakes seemed to feel as if they released on their own. Damage occurred to the car I rear ended and they rear-ended a car in front of them. Damage to all 3 vehicles was light enough that all were driven away after crash. On the way home I noticed the brakes were not working properly and lost stopping power shortly after depressing the brake pedal each time. After a 2 mile trip home like this I check the brake fluid and found it low. Then I saw fluid on the ground and found the brake line was dripping brake fluid. It appears to have ruptured from the pressure of the fluid inside. The lines were also seriously corroded. This appears to be a problem in materials and my 1985 Suburban shows almost no signs of corrosion on the brake lines and is 20 years older. I was ticketed for reckless driving for not stopping because the car that cut in front made it all the way to the center of the lane before I struck it. That car was behind me and went around me and cut in front because I was "driving too slow" according to her. I had left two to three full car lengths in front of me and this bothered her. I had a good amount of distance to stop the truck even after she cut in front, but the truck was unable due to the line breaking when I pushed the pedal hard. The line should be able to withstand that pressure.

Looked under my truck after my brakes failed while driving to work. Was surprised at how rusty all the lines are. Aaa towed my truck home. I spent the next 3 days replacing brake lines. Now I noticed the lines from the master cylinder are rusty as well. Now I will have to replace those as well. I've never had brake lines rust out like these have. My wife drives a little 1999 escort and the brake lines on that are fine. What the heck this is all the use you can expect on a GMC Sierra?

Three months prior I lost power steering because of a metal line leak. Then coming up on traffic I'm applying the brakes and the pedal went to the floor, luckily I was able to pull onto the shoulder of the road to avoid an accident. Had I not been able to pull on the shoulder my GMC would have slammed the vehicle in front of me and would have pushed that vehicle into the car in front of that one. Have not gotten the truck back from the shop yet but I could see brake fluid leaking from a metal brake line. 2005 GMC 88,000 miles this is my first GMC and my last. I think all GMC products should be recalled and fixed!!

As I was leaving home my home and approaching stop sign, my brakes gave out. I located an area near the rear left axle where the brake line was corroded and burst. Inspection of the brake lines shows extensive corrosion along the entire lines.

While applying the brake to shift into drive, the brake pedal "went to the floor". pumped braes once and still no pressure. Was able to hear the leak under the driver side and brake fluid was obvious under the truck. Investigation revealed the one of the lines rusted through at the plastic clip to secure it to the frame near the drivers side floor board.
