Plain-English summary

Brake Parts Inc. is recalling certain aftermarket brake master cylinders sold under the Raybestos, NAPA, and AC Delco brands. The affected parts, identified by part numbers MC391232, M4840, and 18M2578, were sold as replacement parts for 2012-2017 Volkswagen Beetle, 2005-2018 Volkswagen Jetta, and 2007-2010 Volkswagen Jetta GLI vehicles.

The recall is due to a defect where the crimping of the aluminum housing may be insufficient. This can allow the master cylinder piston to pop out of the housing. If this occurs, it can result in a complete loss of braking or unintended brake application, increasing the risk of a crash. Owners may initially notice brake fluid leaking onto the vacuum booster or a change in brake pedal travel and feel.

Brake Parts will notify distributors that sold the product and provide a replacement part free of charge. The recall began on August 13, 2020. Owners may contact NAPA customer service at 1-800-272-5372, ACDelco (GM) customer service at 1-815-759-7328, or Raybestos customer service at 1-800-323-0354. Owners may also contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236 or visit www.safercar.gov.
