i have a dual feed master cylinder like spirit usea but i will be running drum brakes front and rear. 49-54 chevy up frot s10 out back. should i use 10 psi residual valves on the front and rear or does the master cylinder put out 10 psi at one port already ,if thats the case which port has what psi? Do you recomend a proportioning valve or should i be ok adjusting the brakes to suit me?
