Vacuum Brake Booster: Description and Operation

Brake Booster

The power brake actuation system includes a vacuum assisted brake booster, vacuum check valve and vacuum hose. The vacuum hose delivers engine
vacuum to the vacuum check valve. The vacuum check valve is a one-way valve that allows engine supplied vacuum to the booster, and closes when
engine vacuum is removed. The brake booster utilizes engine vacuum to reduce the amount of effort required at the brake pedal to actuate the
foundation brakes.
