Torque: 13 Nm (130 kgf/cm, 9 ft.lbf.)
(d) Adjust the length of the No.1 shackle again.
If it cannot be adjusted, inspect the valve housing.
6. IF NECESSARY, CHECK VALVE BODY
(a) Assemble the valve body in the uppermost position.
HINT: When the brakes are applied, the piston will move down about 1 mm (0.04 in.). 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.
If the measured value is not within standard, replace the valve body.
