Good point, Chris;
On the 721, there are 3 o-rings. =C2=A0Two seal the hydraulic fluid and, as=
you point out, are in contact with that on one side and whatever is in the=
bell housing on the other side. =C2=A0The third is between the transmissio=
n snout and the concentric slave body. =C2=A0It sees only what is in the be=
ll housing. =C2=A0The two that were in contact with hydraulic fluid were sw=
ollen and rubbery, whereas the third was not, suggesting that the brake flu=
id is at fault. =C2=A0On the other hand, I have no idea if the o-rings are =
all the same type of rubber or not.
Pending clarification from Irv, I am going with the Quartermaster fluid, th=
e 721 slave, and the Girling (now TRW) master cylinder.
Phil
