Brake Hose and Pipe Diagnosis Inspection

Inspect the brake hoses and the brake pipes at least two times a year for the following problems:

    • Check the outer cover for road damage, cracks, and chafing.
    • Check for fluid leaks.
    • Check for damage at the brake hose and pipe connections.
    • Check that all hose and pipe mounting hardware is securely in place. Repair the mounting hardware as needed.
    • Make sure all mounting hardware is in place and secure.
    • Replace or repair any parts as necessary.

Power Brake Booster Hoses, Pipes And Fittings

Check all pipes, hoses and fittings for leaks at regular intervals. Make sure the fittings are tight. Make sure all clips, clamps and unions supporting the pipes and hoses are in place and properly secured. Make sure all hoses are installed in a manner that does not cause chafing or wear on the hoses. Check for leaks by wiping the suspected area clean. Spotting leaking fluid is easier when the suspected area is clean. When fluid leaks appear, tighten, repair or replace nearby fittings and bolts.
