Brake adjustment
NOTE: When performing a brake adjustment, inspect the brake components for signs of wear or damage.
NOTE: Brakes that are dragging will affect battery run time and can mimic a bad battery pack.
1. Test the operation of the brakes: See Figure 3.3.
1a. Turn the mower off.
1b. Set the parking brake by depressing the
brake/clutch pedal and pushing-down on the
parking brake pedal.
1c. Attempt to push the tractor. If it can be pushed
by hand without skidding a rear wheel, check
and adjust the brakes.
1d. Release the parking brake.
1e. Attempt to push the tractor again.If it cannot
be pushed with little effort, check and adjust
the brakes.
2. Block the front wheels.
3. Lift and safely support the rear of the mower.
NOTE: Make sure the parking brake is released.
4. Visually inspect the linkage to confirm that it func-
tions properly.
NOTE: Removal of the rear wheel will allow easier
access.
5. With the clutch/brake pedal fully released, check the
gap between the brake rotor and the brake pads.
• There is a fixed pad in the drop axle housing.
• There is a moving pad in the brake caliper.
• Wiggle the brake rotor slightly, and attempt to
insert a 0.010” (0.38mm) feeler gauge between
the rotor and either pad. See Figure 3.4.
6. Adjust the gap, if necessary, so that the feeler gauge slips between the pad and the rotor with light pressure.
• Turn the nut to adjust the gap. The gap should be in the range of 0.010” - 0.015” (0.25mm - 0.38mm)
NOTE: If the brake seems to be sticking, or the rotor is discolored from dragging, remove the brake yoke for
repair or replacement.
• Apply and release the brake pedal, then re-check the gap.
7. Repeat same procedure on the other side.
8. Take the mower off of the jack stands.
9. Re-check the parking brake before returning the mower to service.
10. Test drive the mower in a safe area before returning it to service.
