Another cause could be that the master cylinder doesn't have any free play.=
The actuating rod (connection from the pedal) needs to have about 1/16" of=
clearance from the master cylinder piston when it is released or the bleed=
port in the end of the cylinder may not open and the fluid pressure in th=
e line won't bleed off.

Subject: [Healeys] clutch slave cylinder
Gents,
About 15K miles ago I replaced the clutch (1960 BT7) and put in a new throw=
out bearing. Recently I heard the dreaded metal-on-metal sound when depre=
ssing the clutch peddle. Upon removing the trans, I found the throw out be=
aring completely worn down to the steel casting - hence the metal-on-metal =
sound. On reassembly, I noted that the clutch slave cylinder put constant =
thrust on the push rod keeping the bearing in contact with the pressure pla=
te release arms. Obviously this is what caused the throw out bearing to wa=
re out so fast. I replaced the master cylinder and blead the system extens=
ively - absolutely no air in the system. Yet the slave cylinder continues =
to press the throw out bearing into the pressure plate. Any ideas as to wh=
y this is happening????
