Quick query. Without a booster will a standard manual master cylinder (1") allow me to stop the car with 2.94" diameter disc brake pistons (recon GM FRC4417). Brakes are OK at the moment with drums but my wheel bearing has spun in the hub so seems like I may as well just fit the disc kit if it will work. I don't have enough intake vacuum for a booster and no interest in a complex summer job having had it on the ramp most of the winter.
