Abstract: An improved truck disc brake using a spring loaded safety brake and a pneumatic bladder (68) for releasing the safety brake as well as a service brake enhancing bladder (70) and a pair of rotor brake discs (22, 24). The brake discs (22, 24) are ventilated and include ventilation channels (46) extending radially thereof and vent air is deflected into the brake assembly by means of a scoop (134) on the exterior of the housing (18) passing through openings (148) in the housing and the rotor brake discs (22, 24) act as an impeller moving the ventilation air outwardly thereof to dissipate the heat. A wear gauge (110, 112, 132) is provided to determine the wear of the brake linings (52, 56, 58) and discs (22, 24) and a quick release valve (126) is mounted in the brake assembly adjacent the pneumatic bladder (70) related to the service brake, to quickly release the air when required. Temperature sensors (100, 102) are provided within the brake assembly to read the temperature of the brake assembly. A radial groove (142) extends on the friction surface of the radial disc to provide an air cushion between the brake linings (52, 56, 58) and the friction surface (22a, 22b, 24a, 24b) of the disc (22, 24) and to discharge debris.
