BRAKE SYSTEM WHICH DOES NOT GENERATE POLLUTING WASTE

The invention relates to a brake system (100) for braking a rotation shaft (1), characterised in that it comprises: - at least one piston (4), actuated by means of an electric linear actuator (3), able to move between a retracted release position and a final extended braking position; - a casing (6) adapted to rotate integrally with the rotation shaft, with a cavity closed by a perpendicular cover (5), provided with at least one opening in which the piston (4) is fitted, and the piston (4) having the ability to move forwards into the closed cavity and move backwards, and - a filling occupying the closed cavity, rotating with the casing, consisting of a dispersion (7) or amalgam formed by a powdery or granular product with a lubricating agent.
