Chevrolet C/k 3500 owners have reported 2 problems related to brake master cylinder (under the service brakes category). The most recently reported issues are listed below.
First time the brake failure occurred was in the driveway. My son, a newly licensed driver was taking the vehicle to school when he came back into the house and said the brakes on the truck don't feel right and the pedal goes to the floor. He stated that as he was backing out of the driveway, the brake pedal went to the floor. As a mechanic, I took the vehicle to the shop and found the brake line from the master cylinder to the rear brakes had failed. I replaced this line. Less than a month later another brake line burst when I had my foot on the brake in a parking lot. This time it was the brake line from the tee near the differential going to the left rear brake. All brake lines will now be replaced. My personal opinion is this is a defective part. I know I live in an area where deicing chemicals are used on the roads in winter, however, to avoid rust problems on this vehicle, the underside of this vehicle is power washed weekly during the winter months to remove these chemicals. Frankly, the brake lines do not look that bad. It's like they just develop tiny "pin holes" in specific areas.

Brake lines on my truck rusted thru and brakes failed while on the road. The rusted lines ran from the abs system to the master cylinder and front brakes. It occurred at low speed and I used emergency brake to get home. The lines have not been replaced as yet. I will save parts.
