ABSTRACT:
A fluid disengaged and spring urged brake including a hub having a friction ring mounted thereon with a spring housing in which the hub is rotatably mounted. The spring housing has formed therein a multiplicity of cavities in each of which is mounted a coil spring. A friction facing mounting plate with friction facing thereon is secured to torque pins extended freely through holes slidably mounted on a piston secured to the spring housing. The friction facing mounting plate has a hole extending radially therethrough and the friction facing has grooves formed in the face thereof whereby air pressure supplied through from the hole of the mounting plate passes from the same through the grooves of the friction facing to thereby cool the friction interfaces of the engaging surfaces of the friction ring and the friction facing of the mounting plate. Further the friction ring has at least opening therethrough through which bolts securing friction facing in two pieces may be removed without dismantling any portion of the brake.
