Not true.
Residuals were used on all drum brakes, to the best of my knowledge, up to the mid '70s. Vintage drum brakes really do need residuals, either internal in the master cylinder, or external 10 lb aftermarket. |

He is half right Bob. A 2# RESIDUAL VALVE is used when the caliper/wheel cylinder is above the MC install level to hopefully keep the fluid from draining back into the MC and giving a spongy brake pedal.
I know you know that ...
