Do all master cyl. that are on drum brakes come with the built in 10# residual
valve? I ask because I switched to the dual master cyl. when I put in the 64
front clip and now I am adding disc brakes on the front from a 72 Chevelle. I
am understanding that I will now have to buy a dual master cyl. for disc/drum
brakes. Anyone need a slightly used dual/drum master cyl.? Is there no end?
Ha! Deacon / 55 TF STILL in progress!
