BRAKE BOOSTER
BRAKE
3. Brake Booster
The brake booster is a tandem type that uses two diaphragms.
By utilizing the differential pressure between the intake manifold vacuum and atmospheric pressure,
a high braking force can be obtained even when the pedal depressing effort is small.
The brake booster is installed between the brake pedal and master cylinder. This contributes to im-
prove the response to the brake pedal. If it fails, the brake servo effect is lost requiring a larger pedal
effort, however, the braking force is still maintained.
