I built my 58 w100 with a sweptline master/booster (1.125 bore). It stopped good when the drums system was new. Added front discs. I kept the same master but remove the residual valve. End up with a pedal that went to the floor before barley stopping. After thinking about it, I drilled a new hole in the brake pedal to change the ratio from 6to1 (manual ratio) to 4to1 (power ratio). This gave my a high hard pedal and can easily lock the 9x16 Power Kings. Changing the ratio causes the piston to move more fluid with less effort vs going to a bigger bore. Not sure if it had an effect on the booster.
