ABSTRACT:
A drum brake used in a vehicle generally includes a backing plate secured to a non-rotatable member of a wheel shaft; a pair of brake shoes slidably attached to the backing plate; a wheel cylinder disposed between one end of each brake shoe, where they are closely positioned to each other; an anchor disposed between the other end portion of each brake shoe where they are again closely positioned to each other, and having an anchor block on which each end portion of the brake shoes abuts and an anchor bracket secured on the anchor block for protecting each brake shoe from swinging out; and a substantially U-shaped return spring engaged with each web portion of the brake shoes for biasing the shoes in a mutually approaching direction. The anchor bracket in the abovementioned drum brake is characteristically provided with a supporting portion or portions integrally formed therewith, in order to retain the U-shaped return spring about the central portion thereof for the purpose of restraining the rattling of the same.
