(1) Torque for two stoppers … 140 ± 14 N·m (105 ± 10 lb ft)
Before assembly, apply a small amount of hydraulic oil on the sliding surfaces of the following parts:
- piston (2)
- guide (3)
- barrel (4)
- piston assembly (9)
- spool (14)
(5) Torque for 10 bolts … 175 ± 18 N·m (130 ± 13 lb ft)
(6) 096-1521 Shim
- Thickness of one shim … 1.0 mm (0.040 inch)
-
096-3785 Shim
- Thickness of one shim … 1.2 mm (0.050 inch)
-
096-3786 Shim
- Thickness of one shim … 1.4 mm (0.055 inch)
-
096-3787 Shim
- Thickness of one shim … 1.6 mm (0.063 inch)
-
096-3788 Shim
- Thickness of one shim … 1.8 mm (0.071 inch)
- 096-1522 Shim … 2.0 mm (0.079 inch)
To ensure that the following conditions are fulfilled, install shims (6) :
- When parking brake release port (12) is vented to the air, the motor output shaft does not rotate with a torque of 440 N·m (320 lb ft) or less.
- When pressure at parking brake release port (12) is 780 kPa (115 psi), the motor output shaft rotates with a torque of 49 N·m (36 lb ft) or less. Both the inlet port and the outlet port must be open to the hydraulic tank.
(7) Apply 1U-8846 Liquid Gasket to the seal.
