32.5. There is no linkage adjustment. All adjustment
is done at the brake caliper.
32.6. To reach the brake caliper, lift and safely support
the right rear corner of the tractor.
32.7. Remove the right rear wheel of the tractor using
a 3/4” wrench.
32.8. Hydro-Gear transaxles use a castle nut locked
with a cotter pin.
See Figure 32.8.
32.9. Insert a .015” feeler gauge between the brake
rotor and the outer brake pad. There should be
slight drag on the feeler gauge.
32.10.If the feeler gauge is too loose, or will not go in,
brake caliper adjustment is necessary.
32.11. Remove and discard the cotter pin. A 1/2”
wrench will turn the adjustment nut.
See Figure 32.11.

32.12.Tighten the nut to reduce the clearance. Loosen
the nut to increase the clearance.
32.13.Check the movement of the brake arm:
• The brake arm should move forward as the
brake is applied.
• The return spring should draw the brake arm
back against the spacer when the brakes are
released.
32.14.Visually check the thickness of the brake pads:
they are visible within the caliper.
32.15.Check the brake rotor:
• Confirm that the brake rotor floats on the splined
shaft by sliding it in and out with light finger pres-
sure.
• If it binds on the shaft it may cause brake drag
and reduced holding performance.
• A rotor that has been dragging will frequently be
discolored by the heat (blue).
32.16.If the brakes are dragging or worn, or if the rotor
needs to be removed from the shaft, remove the
two nuts that hold the caliper to the transaxle
using a 7/16” wrench.
See Figure 32.16.
32.17.Remove the return spring. The end with the
small hook seats into a notch on the brake arm.
The end with the large hook goes around a
spacer on the lower stud.
