68 FJ40 converting to dual circuit MC (5 Viewers)

[4x4veteran]

Hello, I know old thread! Which wilwood kit are you referring to? I checked their site and done see anything. Thanks!

Sorry for not answering right away.
Been off line for a while.
It's a long story and will come out in paperback this fall.
I bought the MC through Manna free.
The booster through Summit.
Made the drums feel strong for about a week before I got the disk kit from Manna free.
The Cruiser is a 1970 FJ40.

AKA: Ugh.... Where the F does time go ?

Bought this FJ40 seven years ago and started on converting the single-circuit Brake Master to a dual, parts purchased from Mark's Off Road, as well as a rebuilt steering box from Mark, then shizzle happens and I threw some tarps over it and WHAM! seven years later....

So the Cruiser Gawds gave me a dream the other night that I needed to see what's under those ratty tarps, so I pulled everything off and cleared out the dead opossum carcass from underneath, and got out the leaf blower and cleaned all the Black Widows and leaves and Morning Glory vines.

*** The reason for this thread bump: Anyone have additional pictures of where and how they ran the new dual brake lines? Also, I see these's a MAF dual-master kit that contains Residual Pressure Valves for each circuit. Are these necessary ? What is the function? LINK

Thanks !

residual valves are a check valve to keep the brake shoes applying a small amount of pressure against the drum. on a drum brake 40 they are built into the master cylinder. I would use a master from 70-74 if you are going to stick with the front drums.

Mark, if you see this, I have a ?, do the late 70' production dual circuit brake MC's have the three bolt pattern ? Mine had 4 wheel drum with a dual circuit MC and booster , trying to determine if it came in late 70' that way or someone changed stuff around.

I am staying with front drums. MC is from Mark A. It's what he uses...
