Brake distribution block

[PasiR]

What's the difference between disc/drum power/non power distribution blocks?

The drum distribution block is just what is sounds like, it just distributes the fluid. On disc brake cars there was a pa portioning valve in addition to the other so the back brakes wouldn't lock up before the front. Also, even though they didn't make it that long there was a valve to keep the brakes from locking on glare ice.That went away in 72 or 73, but not sure. You don't really need one of those, unless you're doing a concourse restoration.

So I was on the right track, I'll use my original block w/o extra valve for front brakes. At the moment my repop unit is leaking like...

I have read that a lot of the repos leak. I switched over to disc brakes, and hope mine doesn't leak. If you ever do discs, you can keep your original, and just put an adjustable valve down stream.

Yep - crap parts sucks.

Oh, just to clarify, the valve is for the rear brakes.
