ABSTRACT:
A tool for adjusting a brake mechanism of a truck-trailer comprises a lever having a spanner at one end thereof for manually moving an actuating arm of the mechanism between released and actuated positions, and a plurality of socket members for turning an adjustment screw on the arm, the socket members being adapted to fit adjustment screws of different head configurations. A removeable socket member is provided on a swivel device for use on awkwardly located adjustment screws and for use with interchangeable sockets. A coupling for the removable socket member is capable of itself engaging a socket-headed adjustment screw. Turning the adjustment screw with the socket changes of the phase of the arm on the shaft for producing a desired amount of backlash in the brake mechanism.
