[Healeys] HELP - No Clutch

[Bob Spidell]

There's a spring-loaded rubber seal on the end of the pistons on brake 
and clutch M/Cs.  This allows fluid from the reservoir to enter the 
system when the piston is out, but needs to seal off the pipe to the 
reservoir when you press the pedal.  If this fails you might get the 
symptoms you describe (I've had it happen on a brake M/C, but not a 
clutch M/C).   Have someone work the pedal while you watch the fluid 
level--if it rises when your helper presses the clutch pedal this is 
likely your problem.  What puzzles me, however, is where the 'extra' 
fluid is coming from--possibly, the fluid was sucked from the circuit to 
the slave cylinder.

If the M/C is otherwise in good shape--i.e. no pitting--you should be 
able to get by with a rebuild kit.  If not, and your M/C is aluminum, a 
resleeving or new cylinder is in order.
