<p>The brake comprises a brake carrier and a caliper (20) straddling a brake disc (8) and brake shoes and being axially slidable relative to said brake carrier, said brake carrier or said caliper, respectively, being provided with at least one pin (22) which is guided in a bore (14) of said caliper or of the said brake carrier, respectively, and an intermediate layer (40) is provided between pin (22) and bore (14) to prevent metallic contact therebetween. Layer (40) may be applied onto pin (22) or bore (14) and may comprise layer of sliding varnish. Alternatively it may comprise an adhesion-active sub-layer (e.g. zinc phosphate) provided directly on metal surface and onto zinc phosphate layer is then applied a layer of sliding varnish comprising dry lubricant system containing e.g. fluorocarbon, or molydenum sulphite and graphite in heat convertible resin. After curving, grease may be provided and as shown a lubricating groove (23) runs helically around pin (22). <IMAGE></p> |
