Abstract
An external, multi-caliper brake for positive torque controlling as well as for controlling the rotation of a shaft is shown in the preferred brake embodiment of this invention as having a hub arranged to be mounted to the shaft with a longitudinally centrally located, finned friction disc mounted to the hub. A brake housing supports multiple brake calipers which are shown as including diaphragm operated, fluid pressure actuated pistons carrying brake pads which are caused to frictionally engage with the friction disc to rotationally control the shaft. The preferred friction disc is formed of two opposed, interlaced, internally finned component discs to create a serpentine, radial and circumferential, air cooling path for the friction disc and provide better heat transfer and brake efficiency. Another embodiment includes double fins to better cool not only the friction disc but the external calipers themselves. The calipers include quick brake pad change apparatus by use of pinned pad supports and positioning bosses.
