  • The pedal causes the piston in the master cylinder to compress the brake fluid
  • This pressure is then passed on equally to larger pistons in the wheel cylinders
  • This pressure forces the brake pads against the wheels
  • The friction between the wheels and the pads stops the car
  • The brake pedal is a lever
  • There is a pivot between the effort force and the load force
  • The lever changes the direction of the force on the brakes
