Apparatus and method for extending door brake lifespan

Abstract

The present disclosure includes a retrofitted door brake. The retrofitted door brake may, in various embodiments, comprise a hub comprising a cylindrical central axle, a plurality of projections extending radially away from an outer circumference of the central axle, and/or a cam comprising a plurality of pins that hold the projections away from a channel wall of a brake housing. The pins may be configured to break away from the cam to release the projections into contact with the channel wall, and the pins may be fitted with a cover, such that the pins are capable of withstanding abrasion and wear. The cover may comprise a cylinder having an axially running aperture, and/or a beveled edge that shaves a layer of the outer surface from one of the plurality of pins as it is fitted over the pin.

What is claimed is: 
     
         1 . A retrofitted door brake comprising:
 a hub comprising a cylindrical central axle;   a plurality of projections extending radially away from an outer circumference of the central axle; and   a cam comprising a plurality of pins that hold the projections away from a channel wall of a brake housing, the pins configured to break away from the cam to release the projections into contact with the channel wall, the pins fitted with a cover, such that the pins are capable of withstanding abrasion and wear.
