A skate brake particularly suited for an inline skate includes a braking carriage formed of left and right plates spaced apart by axles that support rollers thereon. The rollers engage the wheels of the skate when the carriage is maneuvered to the appropriate elevation, and the momentum of the wheels is arrested as a result of a frictional bearing of the rollers against the carriage surface. The carriage is raised and lowed by a rocker mounted below the skate and coupled to the carriage plates, where rotation of the rocker drives the plates and the carriage downward such that the rollers contact one or more wheels. The rocker is actuated by a linkage that includes a pushrod and a second rocker that is mounted to the skate boot, allowing the user to control the braking carriage by applying pressure to a rear location of the boot.
