Difference in Distribution Blocks

thats what i was kinda wondering...this is the one that would be used on a disc brake setup? or would this be fine for 4 wheel drums?

Its not a proportioning valve. It has the holdoff feature for the rear brakes. This allows the front to begin to take hold before the rear and lessens the tendency to lock the rear brakes. It will work on either drum or disk without a problem.
