It includes two replacement brake shoes with standard 23,000-pound axle rating linings (23K), along with the required hardware like return springs and roller retainers. The shoes are sized for a 4515Q drum brake configuration—commonly found on trailer axles—and are used to restore proper stopping power and parking brake function when the original linings wear down. Replacing the shoes and hardware as a kit ensures even braking and helps prevent brake fade or pulling.
