Auxiliary Brake Testing
The auxiliary brake should be checked for proper
function.
1. Support the rear wheels off the ground.
2. While turning the rear wheels by hand, apply the
auxiliary foot brake. This brake should not stop the
wheels from turning until the lever is half way
between its rest position and bottoming on the
footrest.
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.
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.
