Abstract: A mechanical brake system for inline skates that utilizes all four wheels for braking. The brake is applied by the skater straightening the leg, or both legs if there are brakes on both skates, to a predetermined adjustable position.

Abstract: A braking system preferably for an in-line skate includes a brake pad mounted to a forward end of a skate frame and an elevated front wheel attached to the skate frame by two pivot arms.
