Disc & Drum: Overview Subaru Forester SF

DESCRIPTION & OPERATION

All models are equipped with front disc brakes. Rear brakes are either disc or drum. Legacy models are equipped with hill-holder system. 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.
