The short answer
NHTSA received Robert Bosch LLC’s report on Feb 26, 2013. Copied from NHTSA on Oct 20, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
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.
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.
