A brake hydraulic hose is the flexible section of the brake system. It carries pressurized brake fluid from the rigid line to the brake at the wheel while flexing with steering and suspension movement. Dorman designed this hose to be installed as part of a complete brake repair. Signs a hose may need replacing include cracks, bulging or swelling, fluid seeping at the hose or fittings, or a soft, spongy pedal. Because these symptoms can have other causes, diagnose the system before replacing parts, and bleed the brakes after installation as directed by the vehicle service information.
