         Types of brakes: apparatuses used 
          to slow or stop a moving vehicle. 
          Drum brake: mechanism that slows and stops a car by fiction, 
          by pression brake shoes against a drum. 
          Drum: cylindrical part attached to the wheel, against which the 
          brake shoes are pressed to stop the car. 
          Brake lining: frictional part on the outside edges of the brake 
          shoes. 
          Return spring: part of the brake mechanism that returns the brake 
          shoes to their initial position. 
          Piston: cylindrical part that transmits the pressure to and receives 
          pressure from the brake shoes. 
          Wheel cylinder: type of roller that applies a uniform pressure 
          to the wheel then the brake is activated. 
          Brake shoe: part on which the brake lining is mounted. 
          Brake pads: part activated by the piston. 
          Wheel hub: central part crossed by the axel. 
          Stud: metal pin. 
          Disk: round, flat, piece of metal, pressed against the wheel 
          to slow or stop the car. 
          Brake line: system liquid-transporting tubes. 
          Splash shield: protector that prevents dirt from fouling the 
          braking system. 
          Disk brake: mechanism that slows and stops a car by friction, 
          by pressing a disk against the wheel axel.
