M8 Greyhound clutch problem

[Malcolm Towrie]

Hi, I'm having some problems getting the clutch on our Greyhound to work. Fully depressing the pedal is not disengaging the clutch enough to select first gear without pumping the pedal. I've pressure bled multiple times but no luck so far. I don't think there is air in the line but I'll try benchbleeding the master cylinder.

Anyway, my question is about a long thread on the Restoration forum on here regarding rebuilding an M8. The owner mentions that the original tubing between the clutch master cylinder and slave cylinder was 1/2" copper. The tubing on ours is 5/16" copper. I checked the parts listing and confirmed the original tubing was 1/2". I can't see why the original tubing had to be as large as 1/2" or why the existing 5/16" tubing would affect the clutch operation. But it's a big difference so I thought I'd ask.
