Power Brake Actuation (G2298413): Overview

Power assistance for the braking system is provided by a vacuum operated, non-active brake booster. The vacuum required for brake booster operation is created by the variable flow oil pump with integral vacuum pump. The variable flow oil pump with integral vacuum pump is driven by the engine.

Rigid plastic brake vacuum piping connects the brake vacuum sensor to the brake booster. A check valve is installed in the piping to maintain the vacuum necessary for brake booster operation.
