“I only had 27050 miles when brake lines, burst luckily traveling only 5 MPH. I had to replace all brake lines, rear brake calipers. Then at 28,640 miles I had to replace the master cylinder. What in the world is GM doing? What happened to the quality of GM?”
NHTSA complaint #10491894, filed 2013-01, 27,050 miles“I recently had a brake failure on my 2003 Gmc SIERRA 3500 series truck. I was driving when my brakes gave out. The pedal went to the floor and I was barely able to stop before striking a parked car. I took it to the dealer and was told that my brake lines and calipers are corroded and in need of replacement for a $4200. I had the brakes replaced last february and put less than 1000 miles before this incident. The rear brake pads which were replaced then needed to be replaced because of corrosion issues. …”
