Robert Bosch – Brake Master Cylinder Fluid Indicator Switch

Robert Bosch LLC (Bosch) is recalling certain Hydro-Max brake master cylinders with 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.


Report Received Date 02/26/2013
NHTSA ID 13E011000
Consequence Summary 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.
Corrective Action Bosch will notify customers and replace the fluid level indicator switch free of charge. The recall began on April 4, 2013. Owners may contact the Bosch Technical Support and Warranty Hotline at 1-855-426-7247.
