  • Patent number: 5095603
    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 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. One of the free ends of the brake 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 pivoted 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.
