ABSTRACT A drum brake service tool and a method of using the same is disclosed. The tool comprises a lever having a pair of spaced, parallel arms disposed at one end thereof, the arm lying in the plane of the lever which is substantially parallel to the width of the lever; the arms being adapted to receive a brake spring substantially perpendicularly therebetween. A brake-spring retaining mechanism is disposed proximate the free end of each of the arms to prevent the spring from accidentally disengaging from the tool when it is pivotted on the cam. The retaining mechanisms lie parallel to each other and substantially perpendicular to said plans of the lever and are disposed to engage the coils of the brake spring as the spring is passed over the brake-spring pin of one of the first or second brake shoes. The brake-spring is then engaged in between the arms of the lever. The lever is pivotted on the cam to extend the brake-spring to the point that the other free end of the spring lies proximate the brake-spring pin of the second brake shoe. The free end of the spring is then engaged with the pin of the second brake shoes. The tool may also be used to remove or install a brake roller in the brake shoes. In this instance the tool is provided with a pair of L-shaped spurs mounted substantially parallel to each other on two sides of the lever, said sides being perpendicular to the width of the lever and said spurs being disposed spaced a distance from each other which is being substantially equal to said width of the lever. The spurs are adapted to receive a brake shoe therebetween so as to allow the brake shoe to be removed a sufficient distance from the cam to allow a brake roller to be installed or removed therefrom. It is only necessary to use one hand to operate this tool, leaving the other hand free to position the brake-spring or brake roller for installation or removal."
