You don't say anything about pressure range, but, I would think 1000 
PSI. would not be enough, probably 2000 psi. might be. The tubing needs 
to be steel or stainless, and for various reasons including vibration 
fatigue, copper is a no/no. Might think a bit about a foot can exert say 
200 lbs. force x leverage of the brake pedal linkage (measure a couple 
of cars and trucks (we are thinking hydraulic brakes and not air) x area 
of the master cylinder piston. Are we thinking production with many 
pieces, or one or a few pieces. Some vehicle anti lock may have pressure 
transducers.
