<p>This device for automatically taking up wear for a brake having a disc and a brake pad caliper controlled hydraulically and/or mechanically is of the type having a screw, a nut and a piston exerting a pressure on the screw. A ring having oblique teeth and slidably keyed on the screw meshes with a radial finger member. When braking the ring advances with the screw. When the braking ceases, the screw moves back immediately but as the ring is axially movable, it only moves back under the effect of spring-loaded finger members when the screw and nut system is no longer under load and then rotates, if necessary, the screw with respect to the nut.</p> |
