Inspect the flexible hydraulic brake hoses at least twice a year. The hydraulic brake hoses transmit hydraulic pressure to the calipers from the steel brake lines on the body.

    • Inspect the brake hoses for the following conditions:
       - Road hazard damage
       - Cracks
       - Chafing of the outer cover
       - Leaks
       - Blisters
       - Proper routing and mounting
       - Adequate inspection may require a light and a mirror.
    • If you observe any faulty conditions on a brake hose, replace the brake hose.
