I'm thing about taking off the power brake booster on my 55 chevy because the pedal is hard and it will not lock up the brakes due to not enough vacuum. I have wildwood disc brakes front and rear and would like to hear from a few tri five owners with front and rear disc brakes and what size bore wildwood master cylinder yall are using and the rod location on the pedal for manual brakes or how the same 4 wheel disc brakes are working with the power brake setup. any help would be greatly appreciated.
