The hydraulic brake cylinder is the device that controls and converts non-hydraulic pressure into hydraulic pressure. 

What is the principle of the hydraulic braking system?

The principle on which a hydraulic brake system works is simple. Force applied at one point is transmitted to another location via an incompressible fluid, called the brake fluid. Suitable for 9-inch hydraulic back-plates, this cylinder converts your foot-pedal force into hydraulic pressure that forces the brake fluid into the calipers. Subsequently, this pressure forces the brake pads to clamp the rotor and the slow down the vehicle.

Where should I position the bleed nipple?

Importantly, the bleed nipple is located a the top of the wheel cylinder. Air rises to the top of the cylinder and is released by bleeding the nipple. 

Attach a clear tube to the nipple to return fluid to the bottle when bleeding.
