A brake band for being pulled tight against a drum as a braked member is disclosed. The brake band is composed of a lining and a strap arranged on an outer side of the lining. The strap has an extension extending out from one side edge thereof in the direction of an axis of the drum beyond a corresponding side edge of the lining to form an oil-holding portion between the extension and the drum. The lining defines oil grooves which are open into the oil-holding portion.
