Brake Hose/Line: Testing and Inspection

BRAKE LINE AND HOSES

Flexible rubber hose is used at both front and rear brakes. Inspect the hoses whenever the brake system is serviced, at every engine oil change, or whenever the vehicle is in for service.

Inspect the hoses for surface cracking, scuffing, or worn spots. Replace any brake hose/line immediately if the fabric casing of the hose is exposed due to cracks or abrasions.

Also check brake hose installation. Faulty installation can result in kinked, twisted hoses, or contact with the wheels and tires or other chassis components. All of these conditions can lead to scuffing, cracking and eventual failure.

The steel brake lines should be inspected periodically for evidence of corrosion, twists, kinks, leaks, or other damage. Heavily corroded lines will eventually rust through causing leaks. In any case, corroded or damaged brake lines/hoses should be replaced.

Factory replacement brake lines/hoses are recommended to ensure quality, correct length and superior fatigue life. Care should be taken to make sure that brake line/ hose mating surfaces are clean and free from nicks and burrs. Also remember that the brake lines are serviced as a whole assembly with the rubber hoses in a solid crimp design.

Use new copper seal washers at all caliper connections. Be sure brake line connections are properly made (not cross threaded) and tightened to recommended torque.
