Abstract
A band brake drum assembly (50) is provided and includes a brake band member (52), a generally round and/or cylindrical and brake drum (54) which is disposed concentric to band (52), and an input or hub shaft (56 which is fixedly coupled to and rotatably drives drum (54). Drum includes an interior surface having a recessed portion (62) which is effective to retain a certain amount of lubricant or oil within the drum, and several relatively large drainage holes (70) which are effective to quickly drain excess lubricant from drum (54), thereby providing a consistent amount of lubricant wit in drum (54) and improving the overall performance of the brake band assembly.
