HINT: One turn of the nut changes the fluid pressure as shown in the following specification.
7.5 kPa (11 psi)
c. Torque the lock nut.
Torque: 25 Nm (18 ft.lbs.)
d. If the pressure cannot be adjusted by the No.2 shackle, raise or lower the valve body.
Low pressure-Lower body
High pressure-Raise body
e. Torque the nuts.
Torque: 13 Nm (9 ft. lbs.)
f.

HINT: When the brakes are applied, the piston will move down about 0.8 mm (0.03 inch). Even at this time, the piston should not make
contact with or move the load sensing spring.
b. In this position, check the rear brake pressure.
Front brake pressure
1,960 kPa (285 psi)
3,920 kPa (570 psi)
6,860 kPa (997.5 psi)
Rear brake pressure
1,960 kPa (285 psi)
2,352 ± 196 kPa (342 ± 28.5 psi)
2,940 ± 343 kPa (427.5 ± 50 psi)
If the measured value is not within the standard, replace the valve body.
