Abstract

In an automatic slack adjuster for a vehicle brake, an adjuster member acts on a part of an adjustable strut assembly for maintaining a substantially constant braking clearance between a braking member and a rotatable braking surface, the adjuster member acting on the part through a driven ring, and an overload spring urges a clutch face on the driven ring into engagement with a complementary clutch face on the part so that the driven ring and the part are movable together unless the reaction between the clutch faces exceeds the loading of the overload spring whereafter the driven ring can rotate relative to the strut assembly to preclude adjustment.
