Welcome to FTE hawki_peers.
The bleeder valve is accessible through a port on the left side of the bell housing. The system is a gravity bleed type.
Take the cap off of the master. Open the bleeder valve and allow the fluid to drain out. Keep the master full during this process. Absolutely do not let it get empty.
When the fluid that is draining out no longer has air bubbles in it, close the bleeder valve and top up the master.
If you have a piece of hose/tube that will fit over the bleeder valve, that will help contain the mess.
