<VV> Dual MC fallacies

While the statement below is true, a MC can leak between front and rear
portions, allowing the MC piston (when you push the brake pedal) to pass
through the fluid-You have no brakes at all.... 

You can also have a leak, sometimes very minor, at the main seal end where
the push rod goes into the piston-well, where the piston rides in the MC
bore.  If a lot, the pedal will go right down, slowly.  If a little leak,
you will get pretty good brakes but the pedal will slowly go down-until you
have none.

My motto in a street car:  Always ensure you have a good, sound, operating
emergency brake system.  You can drive many miles home on an emergency
brake.... not that I have done so a lot (only three times total - three
different cars-two cars and an FC)   ;>)

I would change over to a dual MC were I you with a 65.

2.  Dual master cylinders prevent total brake failure due to a line/wheel
cylinder leak.
