24.2.11 ADJUST PARKING BRAKE
the parking brake is a sealed wet type disc brake, so the brake itself
does not need adjusting. However, if the travel of the brake pedal
increases because of looseness of the control cable mount or
elongation of the control cable, adjust as follows.
CHECKING
Depress the parking brake pedal with a force of approximately 30 kg
(66 lb). If the travel of the brake pedal is more than 13 clicks, check
for looseness of control cable mount (pedal and brake end). If any
looseness is found, tighten and adjust as follows.
ADJUSTING
WARNING
Prior to adjusting, always block the tires to prevent the machine from
moving and LOCK the front and rear frame with the safety bar.
1. Pull release lever (1) and release the parking brake.
2. Loosen lockout (2) and remove clevis pin (4).
3. Pull lever (5) at the parking brake end fully to release the brake and
set it in the release position.
4. Screw in clevis (3), align the pin with the pin hole in lever (5) at the
parking brake end, then assemble the clevis pin (4) and tighten
lockout (2).
After adjusting, depress parking brake pedal (6) with a force of
approximately 30 kg (66 lb), and check that the travel of the pedal is
7 - 11 clicks.
