Brake adjustment
NOTE: When performing a brake adjustment, inspect the brake components for signs of wear or damage.
1. Block the front wheels.
2. Lift and safely support the rear of the mower.
NOTE: Make sure the parking brake is released.
3. Remove the cotter pin locking the castle nut on the
brake caliper. See Figure 4.3.
4. Back the castle nut off a few turns using a 9/16”
wrench.
NOTE: Even if the brakes are set to the correct
clearance, inserting a feeler gauge between
the rotor and the brake puck can be very dif-
ficult. Loosen the castle nut first, then insert
the feeler gauge and tighten the nut to set
the proper clearances
5. Insert a 0.030” (0.8 mm) feeler gauge between the
brake rotor and the outboard brake puck.
See Figure 4.4.
NOTE: The tolerance for the brake clearance is
0.020” - 0.040” (0.5 - 1.0mm). The 0.030
feeler gauge will set the clearance at the
midpoint.
6. Tighten the nut until there is slight drag on the feeler
gauge.
NOTE: For even braking, both sides should be set
to the same clearance.
7. Install a new cotter pin.
8. Repeat same procedure on the other side.
9. Take the mower off of the jack stands.
10. Open the bypass valves and check the parking brake before returning the mower to service.
• With the brakes released, the mower should have only hydraulic drag when it is pushed.
• With the brakes engaged, the wheels should slide before they rotate when the mower is pushed.
11. Test drive the mower in a safe area before returning it to service.
NOTE: Check all safety and control features. Do Not return an unsafe mower to service.
