Abstract: Brake is a mechanical device used in automobiles, trains, machineries etc., to slow down or stop the vehicle in shortest possible time at the time of need and to control the speed of vehicle at turns and also at the time of driving down on a hill slope. Frictional brakes, commonly referred as drum brake are used for the purpose. In traditional method, two shoes are used to stop the vehicle by making them press against the rotating drum, in which area of contact of brake lining with brake drum is less. Arc angle of each of the shoes in contact with the brake drum is high and it leads to only 50% of the brake lining to be in contact with brake drum while applying brake. Increase in the area of contact between brake lining and brake drum, was achieved by splitting the traditional two brake shoes into four brake shoes, thereby reducing the arc angle of each shoe. Therefore area of contact was increased, which leads to the braking time reduced by 25% and correspondingly braking distance also reduced.
