Safety & Operating Instructions

The caliper contains four small parts:

the brake pad, the backing plate, and

two small actuator pins (Figures 22 &

23). As you let the caliper hang from its

attaching hardware, keep track of these

parts as they could fall out. Clean away

any debris from these parts and the

inside of the caliper.

3. Pull the brake disc off the keyed shaft

(Figure 24). Be careful not to lose the

shaft key. Remove the old brake pad

from behind the disc. Next, replace it

with a new brake pad, then reinstall the

brake disc.

4. Replace the caliper housing and its

parts: two actuator pins, the backing

plate, and the second brake pad

(Figure 23). Make sure the brake arm

assembly is in the upright position and

the recessed cutout on the caliper is

facing up with the plate to the rear.

Reinstall the two caliper bolts and be

careful not to over tighten them.

5. Testthebrake:Withthemachineona

level surface, set the parking brake and

put the machine in neutral. If the brake

does not engage or hold, tighten the

brake adjustment nut 1/4 turn with a

1/2" wrench. See “To Adjust the

Parking Brake”.

Check the parking brake periodically and adjust accordingly.
