Brake Parts, Inc. is recalling 1,330 brake master cylinders sold under Raybestos, NAPA, and AC Delco brands, part numbers MC391232, M4840, and 18M2578.
The master cylinders were sold as aftermarket replacement parts for model year 2012-2017 Volkswagen Beetles, model year 2005-2018 Volkswagen Jettas and model year 2007-2010 Volkswagen Jetta GLIs.
Due to insufficient crimping of the aluminum housing, the master cylinder piston may not be secured properly, causing a loss of braking ability and allowing brake fluid to leak into the vacuum booster.
If the piston pops out of the master cylinder housing, a change in brake pedal travel and feel may result, including increased pedal effort and reduced brake function, increasing the risk of a crash.
What to do
Brake Parts will notify the distributors that sold this product. The manufacturer has yet to develop a remedy for this recall.
The recall is expected to begin August 10, 2020.
Owners may contact Brake Parts customer service at (815) 363-9000.
