My daughter has to keep having the clutch bled up. She had the fluid changed and that lasted around 3 weeks, she has had it bled twice since and now its only lasting a day. The clutch works but she has to pump it. Any ideas would be good

[asathorny]

Yeah, I'm no mechanic but I would suggest that the system is letting air in, air is compressible and would produce the symptoms which you speak of.

What make of car is it?

Must be air getting in.

Does it loose the fluid?

If so then a leak.

If you can trace the pipe and see if any fluid or possible seal at either the master or clutch end

[Asterix]

I think there's a sealing in the main or slave cylinder leaking.

By the way...

Most common point of leakage is slave cylinder. If you can get to it pop the boot off and see if it's full of fluid. But if your not loosing fluid it's more likely the master cylinder is sucking air. How long since previous fluid change? (not the one just done)
