Abstract: The present invention is a brake system for wheeled skates, and in particular in line skates. The brake system consists of at least one brake disk, but preferably two sets of interleaving disks. The first set of disks are keyed to a wheel's shaft, and the second set of disks are keyed to the inner hub of the wheel. The first set of disks cannot rotate around the shaft which is fixedly attached to the frame of the skate. The second set of disks rotate with the wheel. Both sets of disks are free to move axially. To brake, a skater shifts his weight onto the outside of his feet, which causes both the first set and second set of disks to move towards the inside of the skate and compress together. The frictional force between the rotating second set of disks and the nonrotating first set of disks causes the second set of disks to decrease in rotational speed.
