Brake Hoses

INSPECTION



  1. Inspect the lines and hoses in a well lighted area. Use a small mirror to allow you to see concealed parts of the hose or line. Check the entire length and circumference of each line or hose.
  2.  
  3. Look for any sign of wear, deformation, corrosion, cracking, bends, swelling or thread damage.
  4.  
  5. The slightest sign of leakage requires immediate attention.
  6.  
  7. Check all clamps for tightness and check that all lines and hoses have sufficient clearance from moving parts and heat sources.
  8.  
  9. Check that any lines passing through grommets pass through the center of the grommet and are not forced against the side of the hole. Relieve any excess tension.
  10.  
  11. Some metal lines may contain spring-like coils. These coils absorb vibration and prevent the line from cracking under strain. Do not attempt to straighten the coils or change their diameter.
