Servicing The Brake Pedal Shaft Bushings - Cub Cadet 1000 SERIES Service Manual

Series 1000 and 1500
19.19. A crease in the brake arm acts as a cam. At rest,
the ends of the two pins ride in the peak of the
crease: See Figure 19.19.

• The brake arm pivots on a square-headed stud.
• The two pins are forced against the backing
plate when force is applied to the arm.
• The backing plate rides between the pins and
the pad, to prevent the pins from damaging the
brake pad.
19.20. Replace the pads if they are worn. They fre-
quently last many years unless the brakes have
been dragging.
19.21. Be sure the pin bores are clear of dirt and corro-
sion: either may cause the pins to bind and the
brakes to drag.
19.22. On assembly, apply a small amount of dry
graphite lubricant to the pins and the spots on
the brake arm that they contact. Do not allow
any lubricant to get on the brake pad.
19.23. Install the brake caliper, tightening the two nuts
to 7 to 10 ft.-lbs., then check and adjust the pad-
to-rotor clearance.
19.24. Install the rear wheel, tightening the lug nuts to a
torque of 350 to 500 In.-lbs. Lower the tractor to
the ground.
19.25. After any brake service is performed, test the
brakes as described in steps 24.2 through 24.4,
then test-drive the tractor in a safe area that is
free of hazards, obstacles, and by-standers
before returning the tractor to service.

SERVICING THE BRAKE PEDAL SHAFT BUSH-
INGS:
• If there is insufficient travel in the linkage to fully
apply the brakes, a simple visual inspection
should identify the cause.
20.1. Confirm that the brake pedal is firmly attached to
the pedal shaft. See Figure 20.1.
20.2. Remove the cutting deck to reach the brake
pedal shaft, bushings, and bracket.
20.3. Check for excessive play in the bushings.
Replace them if they are worn.
NOTE: It is suggested that if any of these bush-
ings need to be replaced, replace all of the pedal
shaft bushings at this time. The speed control
pedal shaft bushings are replaced in a similar
manner.
