About redo the brakes on a 94 B350 conversion.

I don't have access to the van right now and need to buy parts ahead of time.

Was wondering if anybody can confirm the flare nuts I'll need for the lines and brake lines diameter.

Below is what i'm guessing...

flare type (Inverted/Bubble) - was thinking inverted
size 3/16, 1/4, 5/16 - was thinking 3/16
thread type - if above, then thinking 3/8-24

Thanks!

 

For those who might stumble across this in the future...

3/16" (3/8-24) flare nuts for pretty much all connections except those at the combination valve (by the master reservoir) which are larger. I just reused the old ones so am not sure what the specs are on those.

 

One of the the proportioning /combination valve flare nuts I reused is leaking. Retightened with channel locks / vise grips but of course they're rounded now. Not sure if that did the trick but figure I outta put in a new fitting and flare.

Anybody happen to know the size of the proportioning / combination valve fitting?

7/16", 9/16"... perhaps chrysler threw in an odd metric 10mm, 12mm?

Isn't there some sort of H-block thing where all of the lines run to under the coolant overflow bottle or the batter tray? If I recall, those used a 1/4-NPT.
