A disc brake unit of the so-called caliper slide type, in which the caliper structure is slidably supported characteristically by a bearing sleeve mounted on a fixed frame within the confines of the caliper structure itself closely to the friction pads thereon. The caliper structure is smoothly slidable with reduced torsional load to which it is subjected upon brake engagement. Reduction in braking effect resulting from lack of smoothness in operation and uneven wear of the friction pads can be avoided effectively.
