Abstract
A drum brake assembly includes a wheel cylinder (36) and extendible assembly (60) disposed between adjoining ends of a pair of brake shoes. The wheel cylinder includes a pair of pistons (40,42) which are in abutting relation with each other and with the extendible assembly to substantially define a non-braking position for the pair of brake shoes. The extendible assembly is operable to move the pair of pistons within the wheel cylinder in response to an excessive clearance between the pair of brake shoes and a rotating drum.
