The brake assist system consists of the following:
Receives, multiplies and transfers brake system input force from driver.
Transfers multiplied input force received from the brake pedal to the vacuum brake booster.
Uses source vacuum to decrease effort required by driver when applying brake system input force. At rest, source vacuum is applied to both sides of the vacuum diaphragm for single booster. Return springs maintain the booster in a rest position. When brake system input force is applied, vacuum to the rear of the diaphragm is cut off, and air at atmospheric pressure is admitted in its place. This provides a decrease in brake pedal effort required. When input force is removed, vacuum again replaces atmospheric pressure within the booster.
Supplies force used by vacuum brake booster to decrease brake pedal effort. The source vacuum for a spark ignition engine is normally derived from the intake manifold.
Enables delivery and retention of source vacuum for vacuum brake booster.
Under normal driving conditions, without the brakes applied, vacuum is allowed to act on both sides of the diaphragm within the vacuum brake booster. When the brake pedal is applied, the effort by the driver is multiplied due to the relative length of the brake pedal in relationship to its pivot point and the point at which the push rod to the vacuum brake booster is attached.
Movement of the push rod causes a valve within the vacuum brake booster to close between the two sides of the diaphragm, thus isolating each side. It also allows a valve to open that allows atmospheric pressure to act on the pedal side of the vacuum brake booster while maintaining vacuum on the vacuum source side of the diaphragm. The movement of the brake pedal pushrod is transferred to the hydraulic brake master cylinder via the vacuum brake booster. The pressure differential within the vacuum brake booster reduces the effort required by the driver in applying the brakes.

Replacing LATCH System Parts After a Crash
Warning: A crash can damage the LATCH system in the vehicle. A damaged
LATCH system may not properly secure the child restraint, resulting in serious
injury or even death in a crash. To help make sure the LATCH system is working
properly after a crash, see your dealer to have the system ...
Vehicle, Engine and Transmission ID and VIN Location, Derivative and Usage
The vehicle identification number (VIN) plate is the legal identifier of the
vehicle. The VIN plate is located on the upper left corner of the instrument panel
(I/P) and can be seen through the windshield from the outside of the vehicle:
Vehicle, Engine and Transmission ID and VIN Loca ...
