DESCRIPTION
The Bendix ® TC-2 ™ trailer control brake valve is a hand
operated control valve which features graduated air
pressure control. The most common application is the
control of trailer brakes independent of tractor brakes;
however, the valve may be used wherever a hand-
controlled pressure graduation operation is needed.
Two types of valves are available. The handle operated
valve is normally mounted within reach of the driver. A
typical installation is a steering column mount. The remote
operated type valve is connected to the operating handle
by a linkage rod.

Bendix ® TC-2 ™ Trailer Control Brake Valve
The TC-2 brake valve is not intended for use as a parking
control valve and should not be used for that purpose.
OPERATION
APPLYING
When the handle or actuating lever is moved in a clockwise
direction from the released position, force is exerted on the
pressure graduating spring through the action of the cam
and cam follower. The force of the spring on the piston
causes it to move down.
