Hyster Forklift J30 40XMT service manual
- GENERAL This section has the description and repairs for the brake system. These parts include the park brake, service brake and master cylinder, the disassembly and assembly of the service brakes and the park brakes. The electrically released park brake is also described in this section. Checks and Adjustments are described at the end of this section. DESCRIPTION The J30XMT, J35XMT, J40XMT J1.60XMT, J1.80XMT and J2.00XMT lift trucks feature dual hydraulically operated service disc brakes and mechanically operated park disc brakes. Both brake systems operate independently of each other although they both use a single disc mounted on the bevel gear shaft of the transaxle for braking.
- The location provides a mechanical advantage for effective braking. The service brake master cylinder and separate reservoir are sealed. The reservoir has a level sensor connected to a warning light in the instrument panel, which displays when the brake fluid is low. The service brake is actuated by the large pedal located in the operator’s compartment. The pedal can be operated with either the left or right foot. The park brake is set by a pedal operated by the operator’s left foot. The park brake is released by operating the release lever located on the left side of the instrument panel. Both a warning buzzer and indicator light are used to remind the operator to set and release the park brake.
- The lift truck may also be furnished with an optional electrically operated park brake. When furnished, the park brake applies when the operator leaves the seat of the lift truck. The park brake mechanism is attached to the park brake linkage at the front of the lift truck and replaces the standard park brake linkage.
