Hey guys. My car had drums all around. I swapped the front to disc and now I need to rebuild the brakes on the rear. The drums are way out of spec and can be machined down, but I'm wondering if the cost of rebuilding the drums on the rear completely is even worth it when you can get a disc swap kit on ebay for under $300.

My question really is, will the original stock distribution block work if I had disc all the way around? I know if you have front disc/rear drum you need the proportioning valve, but I could reuse my distribution block with all disc, right?

My understanding of the distribution block is it seperates the dual master to feed the front and the back seperate. I had a all drum 67 that is now all disc, I removed the block so I could verify that is how it works, and it does.

I plan on using mine for the 4 wheel discs on my car, I don't see a need for the extra expense of a proportioning valve.

Ok, cool. That is what I sort of thought too. But i was worried that it might make the rears grip faster and harder than the fronts, causing the rear to lock up under hard braking.

According to the rules of hyd. systems, the pressure is equal at all points, unless you change it with some sort of device like a prop valve.

I always had doubts about that, it might be equal but is it equal at the same time????? That is the question. The front brakes are a hell of a lot closer to the master than the rear:yes::yes::yes:

I guess I will find out:thumbsup::thumbsup:

Ha! I guess so!

Anyone else have any input before Wally and I find out the hard way if this is a bad idea?

Re-use your dist block, but put an adjustable prop valve in the rear line, AFTER the dist block if it's the type with the imbalance switch.
