Combination Valve

Fig. 5 Combination Valve:

DESCRIPTION
The combination valve, Fig. 5 is a metering valve, failure warning switch, and a proportioner in one assembly and is used on disc brake applications.

OPERATION
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.
