so I changed my front brakes from manual drums with a dual style master to the SSBC
manual disc,it stops a lot staighter,but still required a lot of pedal effort. So I put in a power booster and new dual master, but you still have too push pretty darn hard to slow down quickly. The kit came with a adjustible prop. valve, which I placed between the stock prop. valve for the drums and the rear brakes.Should I eliminate both adj. valve and the stock valve, and put one in from a front disc/rear drum power brake car?Has somebody else had these same issues?
look under the dash, should be 2 holes for the pushrod from the M/C to the brake pedal, try the other hole, it changes your leverage and mechanical advantage.

Thankyou for your replies, I changed the rod to the other hole when I changed to power, maybe I'll put it back. I looked at a few different Pontiacs at the Surrey show today,most of all had the prop. valve up under the master like your pics.So I think I will try a new prop. valve, Its the only old part in the brakes not replaced, other than the pedal. Cheers.
I changed over to factory discs on my A-body, I left the factory prop. valve. The only thing I can say, is that the pedal is real high, , other than that, the pedal felt slightly harder , but in a good way.

I shall find a diagram of the two different prop. blocks and see what the difference is,but I would like to use a factory set one instead of the adjustible one.Must be a spring and check ball system?
Excellent illustration Lefty! and yes , it just controls pressure bias front to rear, the SSBC kit I purchased included a adjustable valve that just limits flow to the rear. Soooo, it will be removed, along with the drum valve, and a proper disc\drum valve will be used. I thank you guys for your input! Andy.
