Abstract: A brake adjustment indicator adapted to be mounted to a mounting bracket which supports a brake air chamber on a surface of the mounting bracket opposite the brake air chamber with the brake air chamber having a rod extending therethrough with one end of the rod adjacent the surface and connected by a clevis pin to a brake arm. The brake adjustment indicator comprises a bracket having an elongated body portion and having on one end thereof a base plate positioned generally at right angle to the base portion. The base portion is adapted to be mounted onto the mounting plate. The elongated body portion has an elongated, continuous slot therethrough, which slot is generally parallel to the rod when the base plate is mounted to the mounting plate. The brake adjustment indicator also comprises a pointer adapted to be adjustably mounted in the slot of the body portion.

Abstract: An anti-squeal system for a wheel assembly having a brake drum and a tire rim mounted in radial spaced relationship is provided with a separate wedge assembly inserted between the brake drum and the tire rim. The wedge assembly has a pair of pads separated by an inclined block which is slidably movable against the pads to force the pads radially outwardly from each other, to exert a selective pressure simultaneously on both the brake drum and tire rim.
