A brake hose is the flexible section of the hydraulic brake system. It carries pressurized brake fluid from the rigid brake lines and flexes as the axle and suspension move. Dorman precision-engineered this hose to perform like the original on the specific vehicles and position it is listed for, as part of a complete brake repair.
Signs this hose may need replacing include cracked, bulging or swollen rubber, brake fluid seeping at the fittings, or a soft or spongy brake pedal. A spongy pedal can have other causes, so diagnose the brake system before replacing parts, and bleed the brakes after installation following the vehicle service information.
