Running the Stock '73-'73 A body front disc brakes and converting the rears to the Disc brake kit from The right stuff on my '72 Demon,
Looking at a Wilwood M/C - prop valve (Looks like good quality)
What bore size for 4 wheel disc manual brakes, and what prop. valve?
Thanks all!

Wally.

My 68 Dart was originally 4-wheel drums. I'm converting to 4-wheel disc. From what I've read, you don't really have to have a prop valve. You can use a stock 4-wheel drum distribution block. I'll be using Dr Diff's 15/16" master cylinder with the adapter.

Which MC bore you use is going to be dependent on your caliper set up. I have 6-piston and 4-piston Wilwood calipers and run a manual 15/16" MC. The 7/8" was a little too much pedal stroke.

The prop valve I use is Wilwoods as well and comes with pre-bent lines. Check you have fenderwell clearance.

That’s the setup I was looking into, damn that sure looks nice.
Will probably go with the 15/16” bore.
Thanks Goody!
