The hazard

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.

What to do

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.
