Hydraulic brake hoses should be inspected at least twice a year. Check brake hoses for the following:

    • Road hazard damage
    • Cracks and chafing of outer cover
    • Leaks and blisters
    • Proper routing and mounting

If you find any of these conditions adjust or replace the hose. A brake hose which rubs on other components will wear and eventually fail.

A light and mirror can be helpful for thorough inspections.

Important: Never allow brake components such as calipers to hang from the flexible hoses, as damage to the hoses may occur. Some brake hoses have protective rings or covers to prevent direct contact with other chassis parts. Besides causing possible structural damage to the hose, excessive tension could cause the hose rings to move out of their proper locations.
