The shop manual explains how to bleed it. There is nothing special about it.

I replaced the master cylinder on my 57 Skyliner a couple of years ago and here is what I remember from the installation:

1) The master cylinder manufacturer recommends a bench bleed of the cylinder before you install it. The process for the bench bleed was included with the packaging as I recall. You basically fill the cylinder and stroke the piston several times to remove air from the passages in the master cylinder.
2) After installing the master cylinder and depending on whether you have broken into the brake lines for other maintenance (brake shoes, cylinders), you start with the farthest wheel from the master cylinder (right rear) and bleed it first by having someone pump the brake pedal up and hold it while you release the brake cylinder bleed fitting. You then proceed to the left rear, right front, and left front.

There are bleed kits that use a vacuum pump to pull the fluid from the lines, but I have never had much success with those.

O'Reilly Auto Parts has the master cylinder for the 57/58 Ford (1" Bore) listed for about $120 at the following link:

The original master for the power brake setup had a larger bore. I believe the non power brake master bore was 1".

I checked the shop manual and the master cylinder for the power assit it has a 1 1/8 bore. All the master cylinders i have found all have the 1 inch bore any idea where i can find one ?

Thanks
