1800 SRM 1038 Description and Operation
General
For the service brake system, there are oil-cooled
brakes at the drive wheels. This service manual has
information on how to drain, fill, remove, disassem-
ble, clean, check, assemble, and install the service
brake system. This service manual also includes
troubleshooting and specifications.
Description and Operation
The service brake pedal (treadle valve) or the de-
clutch/brake pedal, when operated by the driver, con-
trols the flow of oil to the service brake piston at each
drive wheel.
Two to ten friction discs are used in the housing de-
pending on the requirements of the brake system.
Friction discs, each between stationary discs, rotate
with the wheel hub. The stationary discs are locked
to the brake housing. The disc brakes are installed
on the drive wheels and are oil-cooled. See Figure 1
and the section Planetary Gear Axle.
