What kind of Master Cylinder would I use? 4 wheel disc

I know there are a few people on here that have 4 wheel discs. Is it a possibility to use a stock style MC with a proper adjustment on a adjustable proportioning valve? If I am thinking correctly, drum brakes require more pressure than discs, so if I reduced the pressure to the rear, would that work?


I used the stock MC and added an adjustable proportioning on my 4 wheel disc application and it has worked well. I frequently drive the car at 100 plus mph applications. i did this because it was easy and I didn't know any better??

CAUTION---I HAVE READ TO NOT USE A DISK/DRUM MC BECAUSE IT WONT WORK AND YOUR REAR TIRES WILL LOCK UP. (something about an internal valve in the drum cylinder?????????/

My REAR TIRES HAVE NOT LOCKED UP IN 4000 MILES AND I AM STAYING WITH MY SET-UP PLUS THE PROP VALVE WORKS GREAT
