will the '67 and up master cylinder bolt right in on my 66? it looks like it. Also does anyone know where I can find a distribution block for the brake lines? thanks,
Josh

The 'distribution block"...(proportionate valve)...can be obtained at a speed shop...one that does after market braking for older 30's type hot rods...in fact thay may have all the braking upgrades you need...

Well....on an all-drum braking system there isn't a proportioning valve. It actually is just a distribution block. A dual-circuit master cylinder will bolt up to your truck, but you'll have to plumb in the extra brake lines. Since your brake lights are activated via a hydraulic switch, you'll need to either plumb in a tee for the switch or go with the '68-up mechanical switch setup.
The distribution block from an A-body or B-body car with all-drum brakes (1970-earlier) will work, but not from a disc brake car.
I'll see if I can find a picture of the brake lines...I have one somewhere.

Yeah you're correct...the problem is there are too many kids with no experience at the counter of parts houses...if he says distribution block..they will get confused and their head will explode...thay will know it as a porportionate valve...the book will correct the application name...

Here's some pics of the brake lines on a dual-circuit system along with the mechanical switch. This is from a '69 A-100.

Nate-
the A-100 is making progress. I purchased a rebuilt 318 w/360 heads and intake. I am going to pick it up on saturday. I am going to upgrade the brakes while I have the engine out and am having a hell of a time finding a distribution block. do you know if that block is adjusting any pressure? could I just put in a T for the front lines and a T for the rear lines?
thanks,
Josh

Duh.
I can just use the existing distribution block for the front brakes and run the rear brake line from the MC straight to the T for the rear brakes.
I guess sometimes if you think about it for amonth or so the answer just appears to you.

Yes..you can do that. What are you doing for brake lights? Just curious.

I bought an aftermarket switch designed for 30's and 40's "pedal through the floor" cars. It works great and actuates on the long brake arm right under the floor. I'll get a pic and post it. I put that in awhile ago when the brake light switch at the MC disintegrated.

Ah okay...it's similar to the stock setup on the 68-70 A-100's. See the second pic I posted on 9/7. That's the OEM setup.

Does anybody know of a disc brake conversion available for the A vans? My front brakes are shot, so I thought it may be a way to go. (as soon as I can get the front drums free'd up enough to get them off!!)

I'm not sure were I say it, but I thought someone made a disc conversion for A-series vans. I think the V-8 brake drums are the same as the Dodge Charger from about '66 or 67 to about 70 or 72. If so, an aftermarket kit might fit.
As for your stuck drums, they probably have a ridge on them and you will need to back-off the automatic adjusters to get them free.
This should be the rear of the holes (slots) in the backing plates if they were assembled correctly. You might nave to bend a screwdriver or something similar to do this.

The kit isn't listed on his site, but you can talk to the guy directly. He has front disc kits for A-100's. But I think it's only for those that had 11" brakes, not 10". Spindles are different.
