68 road runner with front disc brakes, adding power brake booster

[Tim Carlig]

I’m adding a power brake unit to my 68 roadrunner that has front disc brakes. What do I need in the form of a proportioning valve? Classic industries says I need a distribution valve AND A PROPORTIONING VALVE. Where would I mount these two valves if they’re needed?

I'm fairly certain if you have a disk/drum master, all you need in the distribution block.

If your car had drums originally, then all you need is a proportioning valve in the line to the rear brakes

What I’m looking for is IF my car ALREADY HAS the stock proportioning valve, is all I need to do is to ADD the distribution valve?

This is a distribution block/pressure differential valve, Your car should already have one.

Then all I need to do is add the booster and no other valves? I kinda like to hear from someone who’s already done this.

Adding a booster to a properly functioning manual brake system, (drum or disc) does not require any additional valves.
