 2. Place an absorbent towel around the connection to
    absorb brake fluid. Remove the banjo-fitting bolt
    from the master cylinder. Account for two crush
    washers and a banjo-fitting bolt.

                 ! CAUTION                                                                                 AF676D

INSPECTING

 NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.

 1. Inspect the pin securing the brake lever for wear.
 2. Inspect the brake lever for elongation of the pivot
    hole.
                                                                                                           AF677D
