1. A method for applying sand to the inner radius of drum brake linings, said method comprising the following steps:
- a) applying an adhesive onto the inner radius of a friction lining for a drum brake using a roller,b) applying abrasive particles onto the inner radius of the drum brake lining coated with the adhesive,c) removing the abrasive particles that have not been held by the adhesive from the surface of the drum brake lining,d) curing a coating consisting essentially of the adhesive and the abrasive particles; and
e) joining the friction lining to a brake shoe of a drum brake with the cured coating in direct contact with the brake shoe;
wherein the cured coating increases adhesion between the friction lining and the brake shoe of the drum brake.

Abstract
The invention relates to a method for applying sand to the inner radius of drum brake linings comprising the following steps: a) rolling a UV-curing adhesive onto the inner radius of a drum brake lining, b) applying a frictional grain, such as zircon sand, to the adhesive layer, c) removing the frictional grain not retained by the adhesive from the lining surface, and d) curing the coating by means of UV radiation.
