ABSTRACT:
A disc brake having an improved automatic adjustment mechanism is disclosed. The preferred brake includes a rotary actuating assembly for axially translating a push rod which abuttingly urges a pair of friction element assemblies into engagement with a rotatable disc. A nonrotatable element of the actuating assembly threadably engages the push rod, such that when the push rod is rotated, it is axially advanced to decrease the friction element clearance. A clutch mechanism circumscribes the push rod and communicates, by way of a lost motion connection, with a rotatable element of the actuating assembly to effect rotation of the push rod after a predetermined rotation of the rotatable element. Thus, clearance adjustments are made in response to predetermined wear of the friction elements, thereby maintaining brake clearance within predetermined limits.
