distribution block

[M-100]

Does any one know . Can you use the original drum brake distribution block,when converting to disk in the front?

i cant give the explantion as to why but the answer is no. it has something to do with equalization of the fluid pressure to the front and back brakes. i don't remember which gets more pressure. but the distribution block only splits the fluid to each wheel and doesn't meter it to each wheel like the porportioning valve.

Thanks Fordman, should I buy a new proportioning valve ? Or would a used one work just as well.

[fordman]

i think either or would work. but new you know they are working perfectly. used usually have nothing wrong with them though. and i think they can be rebuilt. i think.

The new front discs need more fluid pressure to move the caliper pistons. The old wheel cylinders dont need hardly any.

I don't even know if you can buy a new prop valve for bumps. BUT, guessing if you could at least $100 or more??? no clue. Likely a used one from salvage anywhere from $5-25 at very most. Only aggravation in removal is if the dead vehicle on flats, as usually my case and you get into the "propping a dead vehicle" up with spare rims and tires laying around which can be kinda concerning. Plus the lugging a jack and bucket of tools aggravation out there to the dead truck. Prop valves are weight specific in the proportioning, so make sure the used one from similar to what you reuse on. Don't grab one off a Mercury comet or something as the weight is different and might affect your breaking, but that could likely be addressed with an inline valve they sell, but that's another $40 or so.
