Auxiliary Brake Adjustment (Hydraulic)

Use the following procedure to inspect the hydraulic
auxiliary (foot) brake system and adjust or bleed if
necessary:
First, check foot brake effectiveness by applying 50 lb.
(approx.) downward force on the pedal. The top of the
pedal should be at least 1 inch, (25.4mm) above the
surface of the footrest.
1/8, to 1/4,
Free Play
If less than one inch, two things must be examined:
Free Play:
Foot Brake Freeplay:
1/8 - 1/4" (3.2 - 6.35 mm)
If free play is excessive, inspect pedal, linkage, and
master cylinder for wear or damage and replace any parts
as needed.
Bleeding:
If free play is correct and brake pedal travel is still
excessive, air may be trapped somewhere in the system.
Bleed the hydraulic auxiliary brake system in a
conventional manner, following the procedure outlined in
Brake Chapter 9.
