ABSTRACT:
A brake actuator is provided which utilizes either a mechanical or fluid actuation mechanism. The fluid is transferred from an activation reservoir through a tube to an expansion chamber which activates an extendable piston of the brake. The fluid is contained in a closed system and may be biased to a non-braking state so that the wheels will automatically return to their freely rotating state without any further action by the skater after braking. The upper reservoir fits between the liner surrounding the users calf and the back of the skate. The lower reservoir is positioned adjacent the mechanical braking mechanism. The lower reservoir is biased so that the fluid returns to the upper reservoir and the brake is deactivated. A buffer can be provided around the upper reservoir to assure even flow through the reservoir and tube and to create a compressible environment. The buffer helps to prevent inadvertent braking and to provide control of the degree of braking. In a mechanical embodiment a piston moves into the expansion chamber.
