Centric Parts is recalling certain Hydro-Mar master cylinders manufactured by Bosch from July 1, 2011 through April 12, 2012.

The master cylinders are equipped with a 2.0 bore and 84 cubic inch reservoir containing a fluid level indication switch and without a differential pressure switch.

The brake fluid level indicator (FLI) may not properly detect a low brake fluid level situation and warn the driver.

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.


Centric Parts is working with Bosch to notify owners and Bosch will replace the fluid level indicator switch free of charge.

Notification to owners began during May 2013. Owners may contact Centric Parts at 1-626-961-5775.
