Driving home, leaving our current locality the brakes failed to work. Were able to press brake to the floor without having the vehicle stop. Investigated the next day (after having to borrow a vehicle) and brake lines are flaking and leaking fluid. Took to repair shop after putting on "temporary" break line (which we found out will not work on our vehicle). Having it replaced but shop called and can not do it and we have to take it to the deaerl to fix since the body has to be taken off and brake lines replaced.
The vehicle’s hydraulic brake lines have rapidly corroded, to the point that they may give out any day. The vehicle has been well-maintained (all service performed by a gm dealer) and has received regular undercarriage washing. In addition, the electronic brake control module (ebcm) has just failed; if a brake fluid leak occurs, there will be no warning or indication presented by the vehicle and the vehicle may not be able to stop. Gm has stated that any repairs for these serious safety hazard conditions would need to be paid out of pocket, with an approximate cost of $2500. A vehicle that is less than 10 years old should not such exhibit corrosion to the point of a safety hazard.
Brake line rusted and leaking brake fluid. Total brake failure.
