[Roadsters] brake line question

I have always done (LHD):  master cylinder, right rear, left rear, right 
front, left front.  If everything else is OK, I have never had a problem 
with pedal firmness.

And, what Bob said about bleeding technique -- continue to flush three to 
five pedal strokes after you last see air.  My wife pumps, I bleed and check 
the reservoir regularly.  Hate it when I suck air into the M/C and have to 
start over....
