Subaru Forester: Maintenance and service / 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. It such cases, it is necessary to
depress the brake pedal using greater
force than usual.
Check the brake pedal free play and
reserve distance according to the maintenance
schedule in the “Warranty and
Maintenance Booklet”...
