ABSTRACT:
An adjusting device for automatically compensating for cable strand elongation in a vehicle parking brake utilizes a rotatable disc cam having a circumferential edge which spirals radially out to effect a displacement of a cable yoke in a cable tensioning direction as slack develops in a cable strand of the parking brake. The disc cam is tensioned by a torsion spring, the entire device having a small number of parts and high operational reliability even when dirty.
