Two problems related to brake master cylinder have been reported for the 2003 Chevrolet 2500. The most recently reported issues are listed below.

1 Brake Master Cylinder problem

Failure Date: 12/29/2011

Went out to the truck, started it and brake pedal went to floor along with a warning beep indicating a problem with the brake system. No syptoms prior to this was given, which is very scary as I could have been driving when the failure occurred. Had it towed to dealership, upon inspection (word for word from invoice) "brake line from abs to unit to rear axle and one rusted thru from master cylinder to abs unit, other lines from abs unit very rusty also, replaced all rusted brake lines, free up brake bleedes and bleed brake system, road tested and rechecked okay" this kind of failure should be unacceptable, truck with this low miles and age, really? cost to fix $1,010. 64 with tow. The dealership replaced the lines with brake lines that will never corrod, why wasn't this done at factory to begin with? I regularly tow heavy equipment, granted the trailers have brakes, but this issue should be recalled immediately before someone gets hurt.
