Brakes
NOTE: The brakes may be repaired in the trac-
tor, using procedures shown on the bench.
1. The brake yoke is located on the right side of the
transaxle. See Figure 5.65.
• The heavy actuator spring connects to the top
hole on the brake arm.
• The light return spring draws the brake arm to
the OFF position.
• Remove the cotter pin and loosen or tighten the
castle nut to adjust the brakes. Use a 9/16”
wrench to set a .015” (.381mm) gap.
2. There are two main reasons to remove the cali-
per: to replace the pads, or to free stuck parts.
3. Loosen both brake yoke bolts using a 3/8”
wrench. See Figure 5.66.
4. Slip the return-to-neutral spring off of the spacer
on the front bolt.
5. The yoke and outer pad will separate from the
transaxle. See Figure 5.67.
6. Inside the brake yoke;
• A steel backing plate fits between the friction pad
and the actuator pins.
• The pins fit into holes in the brake yoke housing.
• The brake arm acts as a cam, pushing the pins
when it rotates.
• A small compression spring pushes the cam arm
away from the pins, helping to release the brake.
