Michael assuming you have some resistance after pumping the pedal, jam =
the pedal down hard and leave it at least overnight, preferably longer. =
Do this repeatedly & you will find the pedal comes up. Don=E2=80=99t ask =
me why, but I=E2=80=99ve done this several times with my own and other =
people=E2=80=99s cars, and it works!

We are having a very difficult time adjusting & bleeding the brakes on a =
friend's BN1.=20
The car has recently under a full ground up restoration so things like =
brake lines including flex lines are new, seals in the brake cylinders =
are new, the master cyl. is new, etc.
We bleed the system so many times different way that I have lost track.=20
We have adjusted the free play to assure that the plunger is able to =
return to the full "off" position.
When we adjust the operating rod to achieve the specified 1/8" free =
movement at the pedal.
We have adjusted the brake shoes to have a very slight drag at rest.
Our issue is:
Excessive brake pedal travel before the brakes begin to be effective.=20
Pumping the brakes temporarily improve the pedal travel issue, which we =
think indicates air still in the system.
We are not having any leaks & the reservoir port is functioning =
correctly, IE: no locking up of the brakes.=20
