ABSTRACT:
A brake system comprising a brake drum having an outer peripheral surface, and a brake band including a flexible band-shaped metal member having fixed and actuation brackets mounted near the opposite ends thereof. The band-shaped metal member is wound around the outer peripheral surface of the brake drum with the fixed bracket being fixed to an anchorage pin. The brake band also includes a lining member fixed on the band-shaped metal member. An actuator is coupled to the actuation bracket for acting a force on the band-shaped metal member to bring the lining member into surface contact with the outer peripheral surface of the brake drum at a speed. Oil grooves are formed in the lining member for discharging oil from a space between the lining member and the brake drum to control the speed at which the lining member comes into surface contact with the brake drum. The oil grooves have an oil discharging capacity increasing as going from the fixed bracket toward the actuation bracket.
