Abstract
A brake adjuster for implementation between the brake housing and pressure plate of a brake disk stack. A casing is fixedly secured to the brake housing and receives therein a spring follower. Maintained within the spring follower and engaged at one end thereof is a tubular member. Passing through the tubular member and through the casing is a shaft, the shaft being fixedly secured to the pressure plate at a first end thereof and maintaining a multi-sided broach on the other end thereof. The broach is of such geometry as to make contacting engagement with the interior surface of the tube. Upon successive brake applications, the broaching or cutting surfaces of the broach cut portions of the inner wall of the tube, allowing the shaft to telescope from the casing in order to maintain a fixed built-in clearance among the disks of the brake disk stack. There is no frictional engagement between the broach and the inner wall of the tube and, consequently, no difference in the static and dynamic load characteristics of the adjuster.
