摘要： An improved drum brake assembly in which brake shoes are mounted on a backing plate and coact with a rotating brake drum mounted on an axle and in which a mechanical brake adjuster has a movable component for adjusting the running clearance of the brake shoes, in which the brake drum has an adjustment access opening formed in its generally radial portion and in spaced relation to the brake backing plate. This access opening is alignable with the movable component of the brake adjuster by rotating the brake drum on the axle so as to position the access opening in opposed relation to the position of the movable component. The access opening is sized so as to provide for the insertion of a brake adjusting tool from a position adjacent the lateral side of the drum to engage the movable component, for the purpose of adjusting the shoes, and obviating the necessity of moving under the vehicle to access the movable component through the conventional access hole formed in the backing plate. The access opening is formed as an arcuately elongated slot, the long walls of which provide a convenient pry surface for the brake adjusting tool.
