BRAKE BOOSTER





The brake booster is located on the driver side of the engine compartment, and is sealed to the bulkhead with a gasket and secured with 4 studs and locking nuts. The brake booster actuating push rod is attached to the brake pedal with a clevis pin. The brake booster output rod locates in the primary piston of the brake master cylinder.
The brake booster is a compact unit that occupies less space than a conventional brake booster, improving the vehicles crash performance characteristics. The unit is installed with tandem diaphragms that are 203.20 mm (8.00 in) and 228.60 mm (9.00 in) in diameter and operate as a single unit.

VACUUM PUMP









For both gasoline and diesel engines, the vacuum pump is attached to the rear of the engine and driven by the intake camshaft.
On diesel engines, the vacuum pump has an additional vacuum port, which is connected to the EGR (exhaust gas recirculation) system. For additional information, refer to Engine Emission Control

BRAKE VACUUM SENSOR





The brake vacuum sensor monitors vacuum reserves in the brake booster. The sensor is mounted in the vacuum pipe and hardwired to the ECM. For additional information, refer to Starting System
