The clutch brake booster system was a Mark Brigkit (Hispano Suiza) patent. Rolls Royce was the best known licensee . RR started to pay royalties on it when they went to four wheel brakes in 1923. Henry Royce would never duplicate effort to dodge someone else's patent if he thought it was sound. It was used by RR until the end of the SIlver Cloud era as their cars used a dual hydraulic /mechanical system like Hudson.

I was unaware that Pierce system was the same.
