Abstract
A mechanical sensor for a hand brake quick release mechanism having a housing, flexible clamp, and release shaft having a member with first and second elements. A housing member has open and closed ends. The open end is engageable with a housing outside wall at a point radially opposed to the flexible clamp. A first aperture formed through the closed end is in axial alignment with a second aperture through the housing wall and a third aperture through the flexible clamp. A first portion of the slidable member is disposed within the housing member. A second portion extends through the first aperture, and a portion of the first portion extends through the second and third apertures, engaging with the first element when the release shaft is rotated to achieve and maintain full brake release. A device is provided for urging the slidable member inwardly when the hand brake is applied.
