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.

Method for applying sand to drum brake linings

The invention relates to a brake shoe () for disk or drum brakes, which comprises a supporting plate () with a friction pad () attached thereto and at least one wear indicator (), characterized in that the wear indicator () has a wear sensor () for continuous or multi-stage measurement of the wear of the friction lining and a receiver and transmitter unit () for wireless signal transmission, the receiver and transmitter unit being a passive RFID (Radio Frequency Identification) or SAW (Sound Acoustic Wave) transponder.
