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

Inspect the hoses for the following conditions:

    • Road hazard damage
    • Cracks
    • Chafing of the outer cover
    • Leaks
    • Blisters
    • Proper routing and mounting

Use a light and mirror for an adequate inspection. Replace any brake hoses with any of the above conditions.
