The brake has a lever or release wheel that, after a short operation, lifts a brake block over the running surface of the skates and brings it into a fixed position, in which the front wheel and the brake block contact the running surface in two places. The braking action is achieved by the pressure of the weight of the skater on the roller skate and the brake block, which is transmitted to press the brake on the runner surface of the skates.
