Abstract
A sliding unit for a brake comprising a disk and pads made of carbon-fiber reinforced carbon composite materials, characterized in that in evaluation by X-ray diffraction, the sliding surface of the disk to the pads has interplanar spacing of graphite's reflection (002) of disk d002.sub.(disk) of 3.37 .ANG.-3.43 .ANG., and intensity ratio I.sub.(disk) /Ic of 60-90, which is obtained by dividing the integrated intensity of graphite's reflection (002) of disk I.sub.(disk) by the integrated intensity of (113) of .alpha.-Al.sub.2 O.sub.3 as a reference material Ic; the sliding surface of the pads to the disk has interplanar spacing of graphite's reflection (002) of pad d002.sub.(pad) of 3.42 .ANG.-3.44 .ANG., and intensity ratio I.sub.(pad) /Ic of 45-75, which is obtained by dividing the integrated intensity of graphite's reflection (002) of pad I.sub.(pad) by the integrated intensity of (113) of .alpha.-Al.sub.2 O.sub.3 as a reference materials Ic, and d002.sub.(disk) <d002(.sub.(pad).
