Periodically inspect all of the following components:

    • Brake pipes
    • Hoses
    • Connections

A good time to perform the inspection is during an engine oil change. A light and mirror may be needed for an adequate inspection.

  1. Inspect the hydraulic brake pipe and hoses for the following conditions:
  2. • Road hazard damage
    • Cracks and chafing of the outer cover of the brake hoses
    • Leaks and blisters
    • Proper routing and mounting
    • Damage, cracks, dents and corrosion on the brake pipe.
    • If any of these conditions are discovered, replace the affected brake pipe or hose.
  3. Inspect the brake pipe and the brake hose connections for leaks. If leakage is found, verify the torque of the fasteners or replace the pipe or hose.
