AUXILIARY BRAKE ADJUSTMENT (HYDRAULIC)
Use the following procedure to inspect the hydraulic auxil-
iary (foot) brake system and adjust or bleed if necessary.
1. First check foot brake effectiveness by applying a 50
lb. (approx.) downward force on the pedal. The top of
the pedal should be at least 1, (25.4mm) above the
surface of the footrest (see Ill. 1).
If less than one inch, two th ings must be examined:
Free Play:
Free play of the brake pedal should be 1/8 - 1/4 inch
(3.2 - 6.35 mm).
If free play is excessive, inspect pedal, linkage, and master
cylinder for wear or damage and replace any worn parts.
Bleeding:
If free play is correct and brake pedal travel is still exces-
sive, air may be trapped somewhere in the system. Bleed
the hydraulic auxiliary brake system in a conventional
manner , following the procedure outlined in the Brake
chapter.
