ABSTRACT:
In a method for producing a brake shoe (1), particularly a brake shoe for disk brakes in motor vehicles, by preforming a friction lining (6), arranged on a carrier plate (2), from a friction material fed into a press mould and by press-molding the friction material under pressure and heat to form a friction lining (6), it is provided that grooves (8) are formed in the friction lining (6) which are open at least towards the front face of the friction lining, that the friction lining (6) provided with grooves (8) is exposed to a scorching process, that, subsequent to the scorching process, an elastic filling agent (12) is inserted into the grooves (8), and that, subsequent to the insertion of the filling agent (12), the brake shoe (1) is subjected to a drying process, a hardening process or a cross-linking process depending on the filling agent (12) used.
