Abstract
An improved drum-type brake of the cam actuated type incorporating a formed return spring. The return spring is anchored relative to the backing plate in such a way that it cannot move circumferentially or axially but its flexing action is not interferred with. The arrangement for fixing the intermediate portion of the return spring to the backing plate also affords a means for affixing a dust shield to the backing plate. The cooperation of the return spring with the brake shoe and the mounting of brake shoes holds the brake shoes parallel to the backing plate and facilitates servicing.
