Brake Light On problems of the 2001 Chevrolet Silverado 1500

Brake system failure: September 16, 2018 rear brake line snapped while driving causing immediate loss of brake fluid and loss of braking. Owner was driving 20 mph on dirt road and was able to stop vehicle using 4wheel drive low. Brake line was replaced 9/18/2018 and the mechanic noted he'd never seen anything snap like that before without evidence of direct damage. On inspection brake fluid was corroded despite having been recently changed out. Brake system second failure: on April 16, 2019 vehicle failed to come to a stop while owner was braking for a stop sign. Vehicle slowed but didn't stop despite brakes applied. Owner was ticketed for failure to stop. Owner on turning vehicle on after traffic stop saw abs light now on (wasn't on prior to this) and on braking to turn vehicle then failed to brake completely at which point both abs dash light and red brake warning lights came on. Owner again stopped vehicle using 4 wheel drive low. Owner immediately inspected vehicle's brake fluid levels and found fluid was again low despite having just been serviced on April 10, 2019 with engine replacement and brake inspection. Owner added fluid, looked for leaks and on "pumping up the brakes" felt sufficient pressure to then take the vehicle back to the repair shop that replaced the engine and inspected brakes 6 days prior. The vehicle was evaluated by licensed mechanics and determined to have had abs module failure, brake fluid failure (again) and complete brake system failure. The abs control module was repaired/replaced, brake fluid was evacuated, flushed and replaced. The vehicle has been maintained with regular brake system maintenance. It has not been abused or subject to any conditions that would cause the type of brake system failures that it is experiencing. Because of VIN for this vehicle it was not included in gm recall for vehicles having these problems.

Had a complete failure of the braking system when pulling into a convenience store. Pedal went to the floor and brake light came on, but appeared to have a small amount of residual braking on front wheels. Upon inspection the left rear brake line had rusted through. Went straight to garage for repair and was told that all brake lines were in danger of rusting through in several spots. Also entire undercarriage is badly rusted as to rotors, shocks and such. Actually had all rotors replaced about three years ago at Chevrolet dealer in order for truck to pass the state inspection. Have other vehicles even older than this truck with no apparent problems with rust under them. Was told by garage mechanic that he has seen a very large number of chevy trucks of this vintage with same problems. It's a shame, because this truck looks almost new in every other aspect.

Abs and brake light comes on periodacally.
