Abstract
In a double-wrap band brake assembly, an intermediate band is provided with a first friction material forming a first friction surface from a portion of the intermediate band near an apply bracket to a predetermined intermediate portion thereof, the first friction surface working for forming a lubricant film. The intermediate band is further provided with a second friction material having a thickness that is larger than a thickness of the first friction material and forming a second friction surface from the predetermined intermediate portion to a vicinity of a coupling portion of the intermediate band with a pair of outer bands, the second friction surface working for removing the lubricant film.
