ABSTRACT:
A disc brake having a pair of pistons composed of a Devitroceramics having a heat conductivity of about 1.times.10.sup.-3 cal/cm.sec..degree.C. to about 4.times.10.sup.-2 cal/cm.sec..degree.C., a bend strength of about 5 kg/mm.sup.2 to about 55 kg/mm.sup.2, a Vickers' hardness of about 400, and a density of smaller than about 4.0 g/cm.sup.3. A method of manufacturing the disc brake comprises incorporating into the disc brake a pair of pistons which are prepared by mixing the component materials of the Devitroceramics, melting them to a homogeneous molten state, molding the molten materials into a piston-shaped article, annealing the article for crystallization and heating the article.
