Summary derived from NHTSA notice
Reason for Recall
As stated by NHTSA
Brake Parts Inc. (BPI) is recalling certain Hydro-Max brake master cylinders branded as Raybestos p/n MC390565, NAPA p/n 390565, Carquest p/n E151557, and GM AC Delco p/n 18M870. These cylinders contain a 2.0 inch bore and 84 cubic inch reservoir equipped with a brake fluid level indicator switch and without a differential pressure switch, manufactured between July 1, 2011 and April 12, 2012. The brake fluid level indicator (FLI) may not properly detect a low brake fluid level situation and warn the driver.
Reported concern (NHTSA)
If the brake system develops an external leak, it may result in a loss of brake fluid below the detection level of the fluid indicator switch. Without a warning, the driver may be unaware that the brake fluid level is low. A low brake fluid level may reduce the available braking force which could lengthen the required stopping distance and increase the risk of a crash.
Recommended Action
Per NHTSA guidance
BPI will notify customers and replace the fluid level indicator switch free of charge. The recall began in June 2013. Owners may contact BPI at 1-815-363-9000.
