    Abstract: An adjuster mechanism for wedge brakes includes a plunger assembly that carries an adjuster nut coaxially receiving an adjuster screw. The adjuster nut includes a flange having ratchet teeth thereon that engage an upturned pawl integral with a circular spring that is mounted in the housing coaxially with the plunger assembly. The pawl follows the axial movement of the plunger to rotate the adjuster nut to extend the screw from the nut, thereby effecting adjustment of the brakes. However, when ''''kickback'''' forces (hereinafter defined) lock the nut and screw against relative rotation, the spring deforms in a radial direction to prevent destruction of the brake. Upon release of the ''''kickback'''' forces, the spring releases its radial deformation, rotating the adjuster nut in the normal manner.
