Power Brakes on 59

[Gator Alum]

I installed the power brake booster on my stock 59 the other day and am now focusing on brake lines to hook it up. I have done much searching on the web and this forum for some insight.

I purchased the setup from POL with the Disc/drum brake option, however for the short term I am only running drum/drum. I removed the proportioning valve but I read mixed reviews on needing the 10# residual valves for front and back. I apparently need it if MC is below wheel cylinders but considering my truck is stock height and the system never had residual valves, do I really need them? Maybe it has something to do with the booster? Will it keep pressure on the drums so I will have a better brake feel?

Also, does it matter which port goes to the front brake? I was planning on using the one closest to the push rod as I would thing that would get compressed first. The MC appears to have the same size reservoirs. I'm also planning on using the ports on the frame side for easier running of lines.

Any insight/help appreciated. Hoping to finish it up today!

the front port is usually for the front brakes but in your application the mc is backwards so your front brakes should go to the rear port.
less fluid is used on disc brakes so you may not have much front braking using the disc/drum mc
you may be able to swap the ports and have less rear brake and then swap the lines back when you do the front disc conversion

as for the residual valve, i'd put them in. they keep a pre-load on your hydraulics thus keeping the shoes or discs closer to the rotors or drums.
