2022 Subaru Outback Brake Booster
Brake Booster
- The brake booster utilizes the vacuum produced by the engine manifold to reduce the force required to depress the brake pedal.
- The vacuum in the brake booster may be insufficient if the brake pedal is depressed when the engine is stopped or after the vehicle has been parked for a long period of time. In such cases, it is necessary to depress the brake pedal using greater force than usual
