What is wrong
Brake Parts, Inc. (Brake Parts) is recalling certain brake master cylinders sold under Raybestos, NAPA, and AC Delco brands, part numbers MC391232, M4840, and 18M2578, respectively sold as aftermarket replacement parts for 2012-2017 Volkswagen Beetle, 2005-2018 Volkswagen Jetta and 2007-2010 Volkswagen Jetta GLI. The crimping of the aluminum housing may be insufficient, allowing the master cylinder piston to pop out of the housing.
What can happen
If the piston pops out of the master cylinder housing, a complete loss of braking or unintended brake application can occur, 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.
The fix
Recall repairs are free of charge.
Brake Parts will notify the distributors that sold this product, and provide a replacement part, free of charge. The recall began 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.

A recall means the maker found a safety problem and offers a free fix; it does not mean every unit has the problem. Units affected are as reported by the company. Popular models sell more and so have more recalls and complaints. Official public data; texts are shortened. A dealer can tell whether a single vehicle still needs the repair.
