<p>The invention regards a self-adjusting device (12) which can be applied to a shoe and drum type brake assembly (11) to take up the radial play between the shoes (14,15) and drum (13). It includes a link rod (20) anchored to the first shoe (14), a push rod (21) attached to the second shoe (15), a toothed free wheel (23) screwed onto a threaded shank (21') of the push rod (21) and which is made to turn in one direction in order to find and set the axial position of the push rod (21) to the link rod (20), and a bimetal plate or "thermoclip" (24) supported by the link rod (20) which provokes the rotation of the latter when the shoes (14,15) of the brake assembly (11) are expanded during braking. <IMAGE></p> |
