COMBINATION VALVE
The combination valve is a metering valve, failure warning switch, and a proportioner in one assembly and is used on disc brake applications. The
metering valve delays front disc braking until the rear drum brake shoes contact the drum. The failure warning switch is actuated in event of front or rear
brake system failure, in turn activating a dash warning lamp. The proportioner balances front to rear braking action during rapid deceleration.
