<p>The multi-caliper brake (10) for positive torque controlling as well as for controlling the rotation of a shaft (12) has a hub (14) arranged to be mounted to the shaft (12) with a longitudinally centrally located, finned friction disc (16) mounted to the hub (14). A brake housing (36) supports multiple brake calipers (18-25) which are shown as including diaphragm operated, fluid pressure actuated pistons (26) carrying brake pads (32) which are caused to frictionally engage with the friction disc (16) to rotationally control the shaft (12). The friction disc (16) is formed of two opposed, interlaced, internally finned component discs (40) to create a serpentine, radial and circumferential, air cooling path for the friction disc (16) and provide better heat transfer and brake efficiency. The calipers (18-25) include quick brake pad change apparatus by use of pinned pad supports and positioning bosses.</p> |
