AE82 Clutch Master Cylinder

[Mike228]

Does anyone know if these are rebuildable?

Mine is leaking fluid (slowly), but is still functional, so I'd rather not go poking around to try and find out incase I make it worse.

I expect it is just a seal, but are they be disassembled?

Cheers,

Michael

Yes they are with a seal kit.
However if it is corroded in the barrel it will need honing and possibly sleeving.
In which case a new one would probably be a better idea.
Also finding a seal kit might be tricky, if you know a brake shop though they will stock various seals.
