The wedge adjuster is disposed in the cam member such that it is rotatable with the cam member and slidable in the direction extending at right angles with the expanding direction of the brake shoes. The adjuster system also includes an adjusting rod abutting upon the wedge adjuster and threadedly connected to the cam member and an adjusting gear engaged with the adjusting rod and rotated to extend threadedly the adjusting rod, so that the wedge adjuster is urged to thereby expand the brake shoes.
