REMOVAL & INSTALLATION



  1. Clean the connections thoroughly before opening them.
  2.  
  3. Have handy some means of capping the line remaining in the vehicle so as to prevent excessive fluid loss.
  4.  
  5. Use a wrench of the exact size necessary to loosen the fitting. Avoid using an adjustable wrench or pliers, as brake line fittings are easily rounded off.
  6.  
  7. When replacing a brake hose connected to a brake caliper, always replace the copper gasket under the union.
  8.  
  9. Front brake hoses are usually connected to the metal line at a junction attached to the frame or a suspension member. In many cases, there is a U-shaped clip which must be driven out to free the junction.
  10.
