Either the wrong combination of clutch cover and throw out bearing. Or =

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 depressing the clutch peddle.  Upon removing the trans, I found the =
throw out bearing completely worn down to the steel casting =E2=80=93 =
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 plate release arms.  Obviously this is what =
caused the throw out bearing to ware out so fast.  I replaced the master =
cylinder and blead the system extensively =E2=80=93 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 why this is =
happening????
