Abstract
An automated braking-gap adjuster system for mechanical drum brakes includes back plate, a pair of brake shoes having one end pivotally supported on the back plate, a cam member interposed between the other free ends of the brake shoes and adapted to be rotated by a brake arm and a wedge adjuster having its tapered cam surface slidingly abutting directly or indirectly upon the brake shoes. 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.
