Brake Master Cylinder problems of the 2001 Chevrolet Silverado 1500

Rear steel brakeline failure caused by rust-through, causing complete loss of brakefluid. Leak was at bend over frame bracket and fitting for flexible rubber hose for rear axle brake . Did under vehicle inspection of brakelines on vehicle, all brakelines front and rear need replacement because of severe rust and corrosion. Lines between master cylinder and abs brake controller and lines to all service brakes need replacement. Loss of rear brakes caused rear brakes to fail. Remaining front brakes system would have been useless if loss was at high speed.

Experienced brake failure due to corroded brake lines form the master cylinder to abs unit. The brakes failed while attempting to stop at red light on a major highway, causing the truck to enter the intersection. Both main lines blew causing total brake failure. Any vehicle in the north east region (USA) should come stock with stainless steel brake lines, as to prevent such premature corrosion.

The contact owns a 2001 Chevrolet silverado. The contact was traveling 35 mph when he had to abruptly apply the brakes to avoid crashing into a vehicle that drove into his lane. There was an unusual increase in stopping distance and time. The contact inspected the vehicle and discovered that the brake lines from the master cylinder to the abs unit and from the abs unit to the front brakes were corroded. The failure mileage and current mileage was 115,000.

The brakes failed in traffic approaching a stop light. A severe collision was narrowly avoided. The mechanic determined that a brake line between the abs controller and the master cylinder had rusted through causing a sudden rupture and brake failure. In addition, all brake lines were found to be severely rusted from end to end.

Brakes failed while driving down my driveway, and the pedal went almost to the floor. All five lines leading to the abs unit located inside the frame rail, under the drivers seat, are severely rusted and will need to be replaced. One of the lines rusted through and sprung a leak. Since the lines are running along the top side of the frame rail from the master cylinder and to the front wheels, the replacement will be a difficult job. To the best of my knowledge, the manufacturer does not carry replacement lines and they must be custom bent. Since the lines are typically installed on a bare frame without the chassis, the original installation is much easier than field replacement. Given the difficulty of field replacement and the consequences of brake failure, the manufacturer should use a higher quality original part.
