b. InterVehicular Cable. The intervehicular
cable ( 1 ) is used to connect the HEMAT lighting
system to the towing vehicle electrical system
during towing operations. The cable plugs are
keyed so they can be connected to the HEMAT
and towing vehicle receptacles in only one way.
The lights are operated from the towing vehicle.
The cable is stowed in the storage box when not
in use.
2-2. AIR BRAKE SYSTEM
a. Service Brakes. The service brakes (1) are
expanding-shoe on drum type with dust shields
on inside of brake housings. The brake shoes are
actuated by individual air chambers (2) through
camshafts. The air chambers are connected to the
air system valves and tanks through hoses. The
service brakes are normally locked as parking
brakes when the HEMAT is disconnected from
the towing vehicle. Refer to paragraph 2-2c for
operation of the trailer parking brake control.
