You should be able to find a set of seals to try. Lots cheaper than a replac=
ement master.=20
In the past I found this kind of leak by having someone watching the fluid s=
urface in the reservoir while I pressed the pedal down. On my master there w=
as a rise of the fluid where the jet of fluid came out of the reservoir to c=
ylinder hole, causing a =E2=80=9Clump=E2=80=9D in the fluid surface, indicat=
ing a bad seal.=20

The lines are new as is the slave and master. =20
I did disassemble the master to check it out and it appears to be a Girling k=
nockoff. The piston and reservoir shut off valve feel cheaply made. I=E2=80=99=
m thinking that the reservoir shutoff may be leaking a bit until pressure is=
built up thus forcing fluid into the reservoir rather than to the slave. O=
nly way to check is order a new Girling master from Pegasus, basically a $12=
5 gamble.
Right now Donald and Pat are in the problem solving playoffs. =20
Will advise if the gamble pays off
Thanks for the suggestions.=20
