Abstract
A parking brake assembly which includes a lever (15) for operation of a brake shoe (11, 12) to provide a parking function, the lever carrying an automatic latching device for automatically latching to the lever an end fitting (20) on an operating cable (19) and a guide spring (25) extending from an associated brake backplate (13) into contact with the lever. The automatic latching device is in the form of a latching member (22) mounted on the lever which is deflected aside by the end fitting as the cable is fed in a first direction towards the lever within the guide spring and which latches behind an abutment (20a) on the end fitting to latch the cable to the lever so that subsequent movement of the cable in a second direction opposite to the first direction moves the lever to operate the parking function. The end (25a) of the guide spring (25) which contacts the lever (15) is shaped (25c) to also act on the latching member (22) to bias the latching member towards the position in which it latches behind the abutment (20a) on the end fitting (20).
