Slowing for traffic light going downhill and brake pedal went to floor. Pumping did little so used parking break to stop. Cloud of white smoke out of tail pipe as engine shuttered and valves chattered. Front drivers side break line failed from external corrosion shooting fluid on hot exhaust manifold. When peddle went to floor master cylinder passed fluid into booster and through vaccum line into intake of engine causing white cloud of brake fluid burning with gas internally almost shutting motor down and loss of all power. Replaced corroded brake lines and master cylinder. Negligent design and materials quality in my opinion. Now both front calipers drag and shake steering wheel. Where is safety recall? brake lines are not a maintenance item! try replacing one as they were installed to never come off. Would Toyota have been given a pass on this issue for this many years of complaints, thousands of failures, injuries and deaths?.
Brake lines blew to master cylinder.
Recently, I spent three days performing preventive maintenance on my 2005 GMC sierra and found two primary issues that shouldn't be occurring on this young of a vehicle. The first was rotted sections of brake line (supposed to be stainless steel) in the rear of the vehicle (the main line that comes back from the master cylinder) and the second issue was a leaking seal in the power steering pump. There is a considerable number of people with the same problem who have qualified for a recall or work to be done under a technical bulletin, but apparently my VIN lies outside of the acceptable range.
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?.
