An adjuster arrangement for maintaining first and second brake shoes of a brake between a minimum and a maximum clearance with respect to a drum. The adjuster arrangement has a pawl located on a pivot pin on the first brake shoe and an arm that engages a star wheel of an expandable strut. A first leg of a thermo clip is held against the first brake shoe by the pivot pin and receives thermal energy generated during a brake application. During a brake application, the pawl pivots on the pin and imparts a rotary torque to the star wheel to expand the strut to create a maximum clearance while at the same time a predetermined temperature generated during a brake application acts on the thermo clip to moves the pawl out of engagement with the star wheel to prevent rotating the star wheel and thereby sustain a minimum clearance.
