Method and Apparatus for Tensioning an Emergency Brake System on a Vehicle

Abstract

An apparatus and associated method for use in tensioning a park brake cable system includes a body including a housing and an input shaft, the input shaft positioned at least partially within the housing, the housing and the input shaft being axially movable relative to one another, and the input shaft and the outer housing being rotatable relative to one another, the body having a nut receiving recess. The cable system is tensioned by retracting the nut from its support surface, tensioning the system by rotating the nut, and relieving the nut back to its support surface. A control system is used to control the operation of the tensioning device, and is programmable to perform several associated functions.

1 . A tool for tensioning a braking system, comprising:
 a body including a housing and an input shaft;   said input shaft positioned at least partially within said housing, said housing and said input shaft being axially movable relative to one another, and said input shaft and said outer housing being rotatable relative to one another;   a nut receiving recess defined in said input shaft; and   a load cell operationally attached to said input shaft.
