Disc & Drum: Overview Subaru Forester SG

DESCRIPTION & OPERATION

All models are equipped with front disc brakes. Rear brakes are either disc or drum. Incorporated in the primary brakeline from the master cylinder, hill-holder system permits easy uphill acceleration during take-off from a standing/stopped position. Hill-holder is activated when both brake and clutch pedals are pressed as vehicle stops on an incline of 3 degrees or greater. Hill-holder uses a gravity-actuated Pressure Hold Valve (PHV) to control fluid flow to brakes while clutch pedal is fully pressed to floor. PHV is connected by cable to clutch lever.

Operation (Without Gauges)

  1. With the engine off, depress the brake pedal several times applying the same pedal force and make sure that the pedal height does not vary with each depression of the pedal.
  2. With the brake pedal depressed, start the engine.
  3. As engine starts, the brake pedal should move slightly toward the floor. If no change occurs in the pedal height, the brake booster is faulty.
