[Healeys] Heavy clutch question

[Alan Seigrist]

Gary -

It is quite easy to mix up the BJ8 brake master and the BJ8 clutch master.
 On the BJ8, these units are not the same, but on your BJ7, these units are
identical.  If for some reason you've mixed up and put a BJ8 Brake master on
for your clutch master, then you will have the problems your are describing.
