What owners wrote
I am the original owner of a 1999 GMC sierra that just had brake line failure on 7/14/16 on the interstate that caused an acccident. I had complete loss of brakes, pedal to the floor. I used low gear and park brake to minimize damage but still made contact. It is currently at patriot buick GMC in williamsburg va for repair where I bought it new. I feel me having to pay $1000+ for the brake line repair and now a court date and insurance issues that are not my fault.
Stopped in my driveway to get newspaper and mail. I got back into the truck and applied the brake to shift into drive. The brake pedal went to the floor. I coasted up the driveway and was able to stop. When I got out of the truck there was a trail of brake fluid. The leak was coming from under the driver's seat area, where the brake line attached to the ABS pump. My mechanic had to replace all of the brake lines.
