Removal & Installation



  1. Using a brake pedal holder, depress the brake pedal past its first one inch of travel and hold it in this position. This will isolate the master cylinder from the brake hydraulic system and will not allow the brake fluid to drain out of the master cylinder reservoir.
    NOTE
    To access the lower (left rear) proportioning valve, it may help to remove the air cleaner cover and hose to the throttle body.

  2.  
  3. Disconnect the brake tube from the proportioning valve requiring removal.
  4.  
  5. Unscrew the Proportioning valve from the master cylinder.
