Agree, Bill. I use the -3SS and find they give a much firmer feel to the line than some of the large sizes (like that SS sold by van's which is -4 I believe).  I put the -4 on down in Louisiana (only thing immediately available) but the brake with this  larger size hose took more pedal movement to give the save braking effect.  Now both feel rock solid - I like that.

Ed and All,

 -3 is readily available from all the racing sources, use it! Ed, the brake feel is why Holman and Moody first used the SS/Teflon combo durring the Ford GT-40 and later Le Mans projects. The braided lines and the thick teflon liner really do the trick. Bleed the lines well and -3 is more than large enough. I'm still going to use one of the newer auto fluids in my plane, even if I need to get custom brakes or seals to do it. Much safer over all. BTW guys the racers gave up on DOT 5 (silicone based) fluids because they become mildly compressible at high temps. This isn't a problem for our use, as a good system with DOT-5 probably won't ever get hot enough in an aircraft for it to become a problem.
