In a disc brake to which a carbon composite material is applied, it is effective to prevent the friction surface from being exposed to the atmosphere during braking in order to avoid oxidation and oxidative wear of the carbon composite material. Is being considered. At this time, it is effective to increase the volume of the disk as much as possible in order to reduce the temperature rise due to frictional heat generation, but as a result, there is a problem that the friction surface is wide and one-sided contact is likely to occur. To solve this problem, a disk brake device was devised in which a parallel friction surface having steps is formed on the disk surface (Japanese Patent Application No. 5-21063).

In this case, in order to impregnate an inorganic compound having heat resistance and a high melting point, liquid phase impregnation is carried out as a solution dissolved in water or alcohol. As the inorganic compound having both heat resistance and water solubility, it is desirable to impregnate a chloride such as cobalt chloride, copper chloride or magnesium chloride or a complex oxide such as potassium tungstate or potassium molybdate in an amount of 0.1 to 10 vol%. .

(Embodiment 2) A disk made of a carbon composite material is impregnated into the inside because the pores penetrate in the surface direction (horizontal direction in the drawing) rather than in the laminating direction (vertical direction in the drawing). It will be easier. Therefore, in order to surely impregnate the inside with potassium tungstate, after the oxidation resistance treatment as shown in FIG. 4 (A), the friction surface groove 41 is formed on the friction surface as shown in FIG. 4 (B). The rubbing surface was impregnated with potassium tungstate. Here, the groove pattern may be the same circular shape as shown in FIG. 5 (A) or may be a radial shape as shown in FIG. 5 (B). A perfect circle is preferred. The other processing methods are the same as those in the first embodiment. Further, as a result of carrying out the multi-disc brake in the same manner, the braking torque was stable in the case of Example 2 as well, and the thinning of the disc at the spline joint portion was not recognized.
