One problem related to brake hoses, lines/piping, and fittings has been reported for the 1998 GMC Sonoma. The most recently reported issues are listed below.
In April 2006, a brake line on my 1998 GMC Sonoma pickup broke when I applied the brakes at approx 50 mph. I had to stop rather quickly due to traffic backing up on an interstate highway. When the brake line burst, my brake pedal went to the floor and I had no brakes. Prior to this happening, the brakes were working fine. Fortunately, I was able to swerve into another lane and downshift (std shift) to avoid an accident. My mechanic replaced the broken line (from hydraulic abs to junction) and also the rear brake pads and rotors. The truck had 107,000 miles on it when this occurred. I decided to report this because I am concerned that it might happen to others, resulting in a serious accident.
