Rear Brake bleeding question Options

[Frankvw]

Hi all, I replaced the calipers and pads and flex hoses in the rear. (1973 1,7)
Old brake fluid from reservoir removed with siringe and filled with new fluid.
I did set the clearance on the inner and outer on both sides.
Then I did bleed the brakes and checked the clearance again (was still OK)
Now the proportioning valve part....do I need someone to push the pedal to the floor, keep pedal at floor and then I bleed again while pedal is down? Or does it work another way ?
Or is it not needed after what I already did ?
Thanks for your reply !

I use a similar system as the post above, but use air from one of my tires, between 20 and 25 psi., and mini garden hose plastic tube connecting tire air to the brake fluid reservoir via the overflow tube, with the filler cap on tight. Here is a pic of my contraption! One word of caution, keep an eye on the break fluid reservoir, and be sure the fluid level does not get too close to the bottom or you will be pushing air into the system and will have to start again!
