Abstract: A hydraulic brake adjusting device is provided. The mechanical advantage may be automatically increased by pressed the handlebar by riders and then increased the angle lead by the leading plate(s). Thereby, it may simplify structure, be easy to operate, and be capable of automatically adjusting mechanical advantage while riding. Furthermore, the distance between the O-ring on the tube and the through hole of the piston may be adjusted by the screw barrel to make the convex portion push against the tube, the piston, and the push rod.

Abstract: A brake disc is provided with a disc having two braking surfaces respectively formed at two sides thereof and an outer surface formed at the periphery thereof; a connecting hole disposed at the center of the disc; a plurality of through holes angularly spaced apart between the connecting hole and the outer surface, and each being deflectively radiated from the connecting hole toward the outer surface in counterclockwise direction so that an inner surface is formed at the disc corresponding to through holes adjacent to the outer surface and a first and second inner side surfaces are respectively formed toward and away from the counterclockwise direction; and a plurality of cooling fins extending outwardly from the second inner side surface toward the axial direction of the disc so that some parts are not in one plane except the connection of cooling fins and the second inner side surface.
