[TR] TR6 brake master cylinder

[Geo Hahn]

I went with braided hoses up front purely by accident.  A major supplier's
rubber hoses were out of stock and they offered a pair of the braided at no
additional cost to get me back on the road.  Nice guys in PA.

I was amazed at how much firmer the pedal felt (this is with DOT5).  I
still have rubber for the single line in the back which isn't all bad as in
a 'pinch' (pun intended) I can clamp off that line to deal with a rear
brake leak on the road (have had to do this twice through the years).
