A brake hydraulic hose flexes with suspension and steering travel while carrying pressurized brake fluid from the chassis hard line to the wheel end. Signs the original may need replacing include cracking, bulging or chafing, corroded fittings, fluid weeping at the ends, or a soft, spongy pedal. If a deteriorated hose is the cause, this unit replaces it; consult the vehicle service information for the correct fasteners and whether they may be reused.
