When you press the brake pedal, the load is transferred to the brake master cylinder. The piston of the brake master cylinder pumps fluid through the pipes to the brake cylinders. This increases the fluid pressure in the brake actuator. The pistons of the brake cylinders move the brake pads to the discs. With further pressing the pedal, the fluid pressure increases and the brake mechanisms are activated, the rotation of the wheels slows down.
