Abstract

Abstract A disc brake including a fixed support having a pair of circumferentially spaced arms defining a recess therebetween. Each of the arms has an axially extending groove formed therein which slidably receives a projecting ledge on a caliper which is slidably supported in the recess by the arms. Removable keys are carried in the grooves that engage the caliper to retain the latter on the fixed support.
