<p>The device comprises a carrier frame (1, 2) secured to the vehicle in place of the braking means. The carrier frame (1, 2) comprises two supports (5) which are displaceable individually and perpendicularly to the disc (13) to be reworked and receiving two angle grinders (11) driven in the same direction and provided with coaxial cup grinding wheels (12) facing each other and rotating in opposite directions. The brake disc (13) is subjected to a torque which continuously varies as a function of the surface machining of the braking disc, thereby causing the rotation of the disc (13) without any additional drive. The device is provided with a grinding arrangement comprising a cover (16) extending on half of the circonference, and of which the lateral extension covers the disc (13) and at least partially the cup grinding wheels (12). The cover also comprises a connection (15) to connect a suction pipe. Furthermore, the cup grinding wheels (12) are surrounded with coaxial protections (10), the projection of each edge of the cover (16) in a radial plane falling on one protection (10). </p> |
