Brake Proportioning/Combination Valve: Description and Operation
Fig. 8 Combination Valve
Fig. 9 Diagonally Split System Combination Valve
On all models except Capri, the combination valve, Fig. 8 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.
Combination valves used on diagonally split brake systems do not use metering valves instead two proportioning valves are used, Fig. 9.
