clutch problm-bubles

SIIa with a SIII gearbox

Clutch has just gone real soft , does not release drive except for the last inch or if you pump it. I have bled the system and its the same,if you pump you get bubles /froth in the fluid resevior. But the odd thing is if you hold it on clutch, it does not seem to slowly engage the drive as i would expect if the master seals had gone.

Any ideas before i do what seems inevitable and change the master cylinder. Is is a valve of some sort stuck, this just started overnight, it had been standing for 2 months.

Also, i had considered swaping for a SIII dual brake system at some piont, would it make sense to install a SIII master clutch now as they would no longer share a resevior, any1 done this and will it just fit in unmodified ?

Dont wana turn a 3hr job into a 2 day jo in this weather

Have you got a Ser II or Ser III clutch system. If you are using the Ser II system, check that you haven't broken a pin in the cross shaft where it goes into the bellhousing.

The bubbling in the reservoir is usually a sure sign of seals failure in the master cylinder.

Try a seal kit straight away. Or do the new master cylinder job you were trying to put off till the summer.

Sorry, guilty of not reading question properly!

Thanks chaps, new master on the table, just need a few hours without rain and gale force 790 winds. Gona fit a SIII master in prep for changing the brakes to duel circiut servo type(some how)
