Best technique to charge and bleed a complete new brake system?

[JH27N0B]

My restoration project is on the home stretch with only a couple big hurdles to cross.
One of those is getting the brakes finished up.
Everything's installed, and I bled and installed my vintage master cylinder.
I'm using DOT 5.  I installed the master cylinder a few hours ago and was going to try gravity bleeding.
I've got the bleeders open on all 4 corners.  So far, the level of fluid in the MC doesn't seem to have lowered much, if at all.
Do I just let it sit, does it take a lot of time for fluid to drip out and fill the system?
Or do I need to do something else?

generally 2 people , open one bleeder & hold a finger over the bleed screw & pump slowly  move form cyl to cylinder start at the furthest bleed screw , you need the lines to be somewhat full to have enough fluid weight to gravity bleed

I do the bleeder cup method at least to get enough pedal for on and off the trailer, before my mechanic can properly go over the system when he inspects the cars.

I always end up gravity bleeding each corner a couple of times and end up with a pretty darn good pedal.

After bench bleeding the master and installing it, I opened all the bleeders.  I attached a small section of vacuum hose to each bleeder and ran it to a cup so I wouldn't make a mess.  After about 10 minutes, I had fluid dribbling out of each hose.  I closed all the bleeders and had my wife help me bleed the brakes the normal way.

How long did you let yours sit with the bleeders open?

Worked a charm! No waiting....

How long did you let yours sit with the bleeders open?

I looked at it this morning as I was leaving from work, and it doesn't look like the level in the MC has dropped at all.  It's been sitting with all 4 bleeders open for over 12 hours now.
I'm a little hesitant to pump the brake pedal, because on the return stroke it will suck air back into the MC from the brake lines I'd think.
I've done a ton of brake work over the years, but never starting from a complete fresh system.  In the past when I'd replace calipers, lines, wheel cylinders etc, I'd use a combination of pumping and gravity bleeding.  My old Ram had a crappy Delco brake system on it and I'd have to redo the front brakes about once every year and a half, which I'd do with loaded calipers.  I don't anyone at home to help so I figured out a way to use a case of coke propped on my brake pedal to be my "helper" when bleeding the Ram's brakes!

Old proportioning valve or new?  Some reproductions had problems.

At this point, I'd crack the lines loose right after the prop valve and see if you have fluid there.

[JH27N0B]

I am pretty sure it is the original prop valve.  The restoration shop partially installed the brake parts. They put the lines on that needed to be on before undercoating the wheel wells, and they installed the prop valve and lines that go to the MC in the process, they installed all the stainless steel brake lines from the set I bought from Fine Lines or Inline Tube (been so long I don't recall now who I bought my lines from!).
I installed the rebuilt calipers, the wheel cylinders, the hoses, and an NOS master cylinder.
I'm not sure what if anything they did to the prop valve before installing, such as having it rebuilt.  I had DOT5 in the system before disassembling the car many moons ago.

pick up a mity vac kit.  you can at least use it to pull the fluid through the lines to the cylinders, plus you can use it as a vacuum pump

This is what I use most of the time.
Pressure bleeding flushes it out pretty good just be careful everything's attached well.

Read else where, haven't tried this one yet, use a tire valve stem mounted to master cylinder cover and use a bike pump to apply pressure. You'll have to check fluid often though. I think it's about 15psi max.

[JH27N0B]

That mity vac sure seems to be the way to go.  Our tech service guys had something similar when I worked at Brake Parts, a vacuum unit that rolled on 4 wheels iirc for that purpose.
Wish I had access to it now!
Starting to feel a little panic now, the shows less than 3 weeks away!
I've found that time, brainstorming, and often ordering something typically resolves the problems I've encountered over the months with my project, but now I'm running out if the time aspect of that formerly successful equation..

Yea...pretty certain the red sunroof car is going to MCACN show as well. My mechanic still has it, working out the bugs, then I have some detail work to finish up...It's coming up very fast !
Today I was checking out another member's car, BS27R1B 's 1971 440+6 Cuda that is heading to MCACN as well...what a beauty

[JH27N0B]

Hey when your mechanic is done working out all the bugs on the red sunroof car can you send him down my way to work out all the bugs on my red T/A?   
My car is so close yet no brakes and engine not started yet (since run on a stand after rebuild over 4 years ago).
I'm scheduled to be in Mopar alley, but if the car can't move under it's own power (and stop!), I'm not too enthused about trying to get it to the show.  I'm 10 miles from the hall, I could almost push it there, but still..
Under the hood looks near perfect reference restoration, exterior stands out with the single stage paint and NOS stripes, and the vintage polyglas looks sweet on the 450s, I gotta wrap this up and get it there for my Friday move in time at the show!
Hope to see the sunroof car and Ricks V code there!
