Abstract:
A motorcycle wheel brake mechanism comprising:a brake disc attachable to a motorcycle wheel, and a brake pad assembly carried by the motorcycle frame for frictional engagement with said brake disc; said brake disc having two flat uninterrupted annular side surfaces, an inner edge connecting said flat side surfaces, an outer peripheral edge connecting said flat side surfaces, and mounting elements (2) extending from said inner edge for locating said brake disc in an exposed position on a motorcycle wheel; said brake pad assembly comprising opposed brake pads (3) located along the rotational path of said brake disc for pressurized frictional contact with said flat side surfaces; said brake disc having a rotational axis coincident with the wheel rotational axis; the outer edge of said brake disc having an endless circular wave shape concentric around the disc rotational axis; said outer waveâ€”shaped edge comprising recurring wave peaks and valleys spaced different radial distances from the disc rotational axis, said peaks being located on a first imaginary outer circumferential line centered on the disc rotational axis; the inner edge of said brake disc having a circular wave shape concentric around the disc rotational axis, said inner waveâ€”shaped edge comprising recurring wave peaks and valleys spaced different radial distances from the disc rotational axis, the recurring valleys on said inner edge being located on a second imaginary circumferential line centered on the disc rotational axis; each said brake pad having a radial dimension that is substantially the same as the radial spacing between the first and second imaginary circumferential lines, whereby the brake pads encompass the outer and inner edges of the brake disc.
