Abstract: An adjuster mechanism in a drum brake wherein a rotation of a star wheel on a shaft of an extendable strut is limited to a single increment define the pitch of a plurality of teeth on the star wheel. The limitation is achieved by a lever that is carried by a web of a brake shoe has a first blade that in perpendicular alignment with a first tooth of the plurality of teeth while a second blade is offset from a second tooth and located in a plane that is substantially parallel with the pitch. When the lever is pivoted on the web through a predetermined angle, the first blade slides into engagement with a third tooth while the second blade moves through the offset and into engagement with the second tooth to connect the lever with the star wheel. Any further pivoting of the lever by movement of the web toward the drum results in the lever and star wheel moving together.
