The power steering leaks badly on my '57 Ford. I've tried leak stop with no help. Is this a command problem with these cars?

What are you using for fluid? They originally used ATF. Based on what I heard, If your using "power steering fluid" that could be the source of some, if not all, your leaking problem. Due to the different composition of PSF the old power steering units tend to leak.
 
ATF TYPE A is replaced by DEXRON III.

Of course, after repair(s), you perform a complete flush. There is also a filter in the PS reservoir.
 
I rebuilt my steering power assist components about three decades ago and installed all new hoses. It's had a zillion miles on it since then. Never leaked one drop. I have always used Mercon/Dextron ATF.
 
I have used type F for more years than I care too remember;) it is too late now but I would not put a stop leak product in the system.there are a lot of spots for leaks hoses,ram,spool etc find leak then search for repairs if shaft on ram is pitted that is just one to check common spot.they can be rechromed good luck

I'm no chemical engineer, but as far as I know, it's purpose is not a lubricant - it is hydraulic fluid although there may have lubricating value.

1. mass noun

A lubricant is a substance which you put on the surfaces or parts of something, especially something mechanical, to make the parts move smoothly.

Most ATFs contain some combination of additives that improve lubricating qualities,[1][2][3] such as anti-wear additives, rust and corrosion inhibitors, detergents, dispersants and surfactants (which protect and clean metal surfaces); kinematic viscosity and viscosity index improvers and modifiers, seal swell additives and agents (which extend the rotational speed range and temperature range of the additives' application); anti-foam additives and anti-oxidation compounds to inhibit oxidation and "boil-off"[4] (which extends the life of the additives' application); cold-flow improvers, high-temperature thickeners, gasket conditioners, pour point depressant and petroleum dye. All ATFs contain friction modifiers, except for those ATFs specified for some Ford transmissions and the John Deere J-21A specification;[5] the Ford ESP (or ESW) - M2C-33 F specification Type F ATF (Ford-O-Matic)

So in brief, each application (TRANS - P/S) uses it's own lubricant and the usual rule is to use what the manufacturer recommends. You only use another style lubricant if the system has been modified from OEM and/or has been modified and calls for a different lubricant.

The FORD call-out for the '57 is TYPE A which has progressed to DEXRON III (or it's current replacement).

My bet typical of piston rod wear in the middle (straight ahead position) the only fix for
that is the piston rod has to be re chromed rebuilt or get another one. All the oil in the
world will not correct worn stiff seals and worn rods and can not be done at home unless
you have a lathe to cut the weld on the cylinder to take apart. If control valve, that you
can rebuild with a kit most likely its Bendix system.
