<p>In the field of brakes, adjusters are required to maintain a constant clearance between engaging parts, even upon wear. A problem with prior adjustment devices is that they may not release the brakes because of the relationship between the static and dynamic coefficients of friction between their parts and the functioning of return spring mechanisms. The adjuster of this application draws a tube (32) through a die (48) thereby eliminating the noted problem relative to the coefficients of friction. A shaft or pin (36) is connected to the pressure plate (12) of a brake assembly and is interconnected with a reshapable tube (32). The shaft (36) and tube (32) pass through a die (48) which makes swaging engagement with the tube (32). As the brake wears, the tube (32) is drawn through the die (48) and is progressively swaged along the length thereof, The spring follower (20) acts against the die (48) to urge the die (48), tube (32) and shaft (36) to a return position following release of brake pressure. </p> |
