Split Systems for Commercial Vehicle Hydraulic Brakes

Split systems now protecting passenger car brakes against complete failure can serve the hydraulic brakes of commercial highway vehicles.

A tandem master cylinder separates the conventional hydraulic circuitry into two sections. The tandem cylinder has independent fluid reservoirs and bores, and thus it continues to operate either section alone in the event a failure occurs in the other. Because there is no splitting between brakes on the same axle, vehicle directional stability and control is facilitated when either section is operated in the absence of the other.

The tandem master cylinder can be utilized on both light and heavy duty vehicles.
