One problem related to service brakes has been reported for the 2001 Chevrolet C3500. The most recently reported issues are listed below.
The brakse on my 2001 silverado 3500 have been intermittent the past few years. Most of the time they work fine but today was the worst experience of all the rest. I pulled up to a stop light, pedestrians stepped into the cross walk, I stepped on the brakes and went right through the red light. Fortunately the pedestrians were able to jump out of the way as I coasted right through them. The brakes worked fine until I got home then I almost coasted into my garage door.
