Abstract
A manual override mechanism for an electric brake includes a flexible cable having an elongate outer conduit and an elongate inner core extending within the conduit, a conduit end fitting secured to an end of the outer conduit, a housing located within the conduit end fitting and rotatable therein and a core end fitting secured to an end of the inner core. The core end fitting is located within the housing and is longitudinally movable from a first position to a second position such that the end of the inner core moves toward the end of the outer conduit. Preferably, a spring element biases the core end fitting into the second position. Movement from the first position to the second position engages the core with a connecting element such as a helical gear to operably connect the core to the electric parking brake for manual operation thereof.
