Abstract
In order to regenerate a brake lining, preferably for a railway vehicle, a friction lining is worked by machining, starting from its worn surface, and provided with a three-dimensional surface profile. The profiled surface is then coated with an agglutinant, and a fresh friction lining substance is pressed on. The worn surface is preferably worked by profile grinding or profile milling, such that a profiled surface structure is produced having a teeth-like, trapezoidal or meander-shaped profile that is vertical to the surface, wherein the profile depth of the surface structure lies in the region of approx. 1-30 mm, preferably 5-20 mm. The profile is preferably oriented in one direction, crosswise to the main strain of the friction lining during braking.
