Auxiliary Brake Adjustment (Hydraulic)

Use the following procedure to inspect the hydraulic auxiliary

(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 things must be examined:

Free play of the brake pedal should be 1/8 - 1/4 inch

(3.2 - 6.35 mm).

Free play can be adjusted on some models by altering the

length of the pushrod, which is connected to the brake pe-

dal by a clevis. Other models are non-adjustable type (right).

If free play is excessive on a non-adjustable brake, inspect

pedal, linkage, and master cylinder for wear or damage and

replace any worn parts.

To adjust the linkage:

S Remove right hand drive cover to gain access to brake

S Hold clevis (A) and loosen clevis adjuster lock nut (B).

S To increase free play, shorten the pushrod (C).

S To decrease free play, lengthen the pushrod (C).

S Hold clevis and tighten lock nut (B) securely.

S Reinstall drive cover.

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
