Adjusting the Brake Linkage
The brakes have been set at the factory for optimum
performance, but after use and wear an adjustment may
be required.
1. Park the machine on a level surface, turn the engine
off, and block the wheels.
2. Loosen the jam nut on the actuator rod (Figure 25).
Remove the cotter pin retaining the actuator rod.
Increase or decrease the actuator rod length by
rotating the rod. Install the actuator rod using a new
cotter pin and secure the jam nut.

improve brake performance, adjust both the left
and right adjustment rods equally using the same
procedure described in step 2.
