Abstract
An improved drum brake assembly is provided that reduces vibration and excessive movement of the cam washer by including at least one lug extending from a cam tube seal and at least one corresponding notch on a cam washer that positions the cam washer on the cam tube. By reducing vibration of the cam washer, wear of the components of the drum brake assembly is reduced. Reduction of vibration also serves to eliminate unpleasant noise during vehicle operation caused by the vibration. Reducing vibration of the cam washer also decreases contact of the cam washer with other metallic components and surfaces within the vehicle, which protects the cam washer from potential corrosion caused by such contact.
