A strut type automatic gap regulator for a drum brake in which a pair of brake shoes are mounted opposite each other and adapted to be moved apart in a braking action. Toothed portions of a strut engage similar toothed portions of a latch which engages a shoe for linear movement therewith. A first spring extends between the one shoe and the latch to urge the toothed portions together while a second spring extends between the strut and one shoe to bias the strut in a direction to extend its effective length.
