Abstract
A cable operated drum brake has an internal brake operating lever with a quick-attach device for an operating cable. A cable attachment tube projects from a backplate of the brake and the operating cable has an inner cable with a latching formation on the end thereof and a cable outer sleeve. An end portion of the operating cable is slideable towards the backplate within the tube up to a first position at which further movement towards the backplate is stopped by contact between an abutment on the tube and a cooperating abutment on the cable outer sleeve. When the latching formation has moved past the quick-attach device, the cable is then subsequently moveable away from the backplate within the tube to a second position in which the latching formation is fully engaged with the quick-attach device. A fastener maintains the latching formation engaged with the quick-attach device during subsequent operation.
