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.
