Looking for intel on what hydro boost to use for my 77 Jeep Wagoneer. Switched to 4 wheel disc and want to go Hyrdo over vacuum.
Thanks
 
Suburban?

I actually have one from an '82 Chevy pickup. C20. Was originally a diesel truck. I have everything from the pump to the lines and so and so forth.

Full manual.

I'll never adapt power brakes into something again.
Size your master cyls and pedal correctly and you'll have the same lush pedal feel all the time, running or not.

This^^. But I used one from an early 80s GMC 2500. Corvette MC. When plumbing back to PS pump and Hydr unit use a Y connect block. I've done two. 74 Scout II (4Whl disc) and 48 GMC trk on a 78 frame. (Front disc rear drum 14 blt)
 
On my Wag, I used a booster from a 99-04 era power stroke super dooty. Mainly, because they were available as take offs cheap and have/had parts availability at your local ONapaZone...

You need way more travel to make it work equivalently though. Every single moving part of a brake system has slack that needs to be taken up.
 
Wide Open Design makes a full kit with Pedal if needed.

It's a cool piece but good fucking luck packaging that in anything with a stockish firewall and dashboard.

It's more of a thing for the tube buggy builder crowd.

Edit: Nevermind, I confused it with the 9:1 manual pedal assemblies that BKOR makes.
 
I don't. It's been gone over 100 times on the old board and i'm sure somewhere here too.

I know that it stopped better than anything else I've ever built. All the time. Running or not. So much so that I built my willys wagon with full manual as well. I know that the new owner is happy with it as well.

I'll never build a power brake system again. It just works.
heres the brake calculator from the old site that is used to calculate masters/pedals. I don't remember who originally created it. BillVista maybe?

That's not a good way to measure braking performance.
Maybe you could have done better with power brakes.

I understand that and you are not wrong.

Just throwing you another option out there that I and many others believe is a great way to go. Good luck! :beer:
