A brake drum is disclosed which is configured for providing an external visual indication of braking surface diameter safe operating limits while installed on a vehicle and includes one or more indentations in its outer surface overlaying the area defined by the interior braking surface where the depth of an indentation is at least co-level with a prescribed safe operating diameter of the braking surface.

Heavy duty brake drum wear indicator

One embodiment of a brake drum includes a cylindrical main body portion, a brake drum mounting flange portion, a brake drum transition portion, the brake drum transition portion extending between the cylindrical main body portion and the mounting flange portion, the transition portion having a plurality of vent openings, and one air scoop secured at each of the vent openings, whereby rotation of the brake drum and air scoop induces air movement within a brake drum cavity defined by the main body portion. Each air scoop defines a louver opening which faces the angular direction of drum rotation, an air channel in fluid communication with the louver opening and the brake drum cavity, and a deflection surface located in the air channel. The deflection surface is positioned to re-direct air movement entering the louver opening at an angular direction, to a generally radial and inboard direction.

Brake drum with vent hole and cooling scoop

The present invention provides a drum or rotor wheel hub having a cast hub having a machined pilot in a flange portion and a machined pilot in a cylindrical portion, and a cast portion which separates the cylindrical pilot from the flange pilot, whereby a machined radii is not incorporated in the pilot construction.
