Proper manual brake setup?

Looking for some information regarding the right master cylinder, brake pedal and everything else involved with switching from power assisted to manual brakes.

I put a built motor in my 86 and hardly make enough vacuum for my old brake setup.
I pulled the brake booster off and modified the pushrod and remounted the power master cylinder. I didn’t have any major issues stopping but it did take ALOT of effort.

Now I have the truck down again and I need to do it right this time.

Would it be worth it to just get a master cylinder kit from jegs or summit?
Will my brake pedal work fine?
What size master cylinder do I need

Get a vacuum pump and be done.

Re: Proper manual brake setup?

I think the manual brake pedal has its push rod attachment point closer to the pivot then the power brake. Gives more leverage so you don't have to push as hard. Not sure if all pedals have both holes or there are different pedals for each type.

Another option would be a hydro-boost system. But more cost and a new PS pump.

I’d rather not deal with a vacuum pump and spend the extra money on another power assisted setup.
