Bleeding Wilwood Brakes Help Please.

[72Z/28]

Hi

I have recently installed wilwood brake calipers and new MC & proportioning valve as well. I am wondering how to bleed the entire system.

I did the bench bleeding of the MC, once I ensured all the bubbles are gone, I put back the led, tightened the four screws to prevent spillage of Brake fluid, and installed the MC on the car.

So the next step is to bleed the entire system, and there is no fluid at all in the brake lines. Not quite sure how the gravity bleeding will work in this case since MC has check valves preventing fluid to pass through the outlet ports to the lines and then to calipers.

So just wondering if someone can advise the proper method to proceed with the bleeding of the system, and this will be appreciated.
