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 pipes on the body.

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