[Healeys] Clutch master cylinder failure

[Peter Schauss]

My clutch master cylinder has suddenly started leaking through the seal
where the pushrod enters the body.  This event happened shortly after I
moved the driver's seat forward on notch.  Is it possible that it was the
result of my pushing harder on the clutch?

I last replaced the master cylinder about 10 years ago (31k miles).

Thanks,
