All brake pipes, hoses and connections should be periodically inspected. A good time to perform an inspection is during an engine oil change. A light and mirror may be needed for an adequate inspection.

  1. Inspect the hydraulic brake pipes and hoses for the following conditions:
  2. • Road hazard damage
    • Brake hoses for cracks and chafing of the outer cover
    • Leaks and blisters
    • Proper routing and mounting
  3. Inspect brake pipes for damage, cracks, dents and corrosion. If any of these conditions are discovered, replace the brake pipes or hoses as necessary.
  4. Inspect for leaks at the brake pipe and brake hose connections. If leakage is found, verify the torque of fasteners and/or replace the pipe or hose.
  5. Inspect the caliper and wheel cylinder boots for leakage. If leakage is found, rebuild or replace the assembly. For service procedures, refer to Brake Caliper Replacement in Disc Brakes or to Wheel Cylinder Replacement in Drum Brakes.
