Clutch reservoir black sludge - dissolved 'o'rings?
Hi All.
A couple of years back I fitted a Tazu clutch master, all went well for some time. Late last year the clutch is feeling poor so I bled new fluid which cheered it up. The old fluid was a bit murky. I've just bled it again - the fluid in the reservoir is properly black (though the fluid at the other end was fairly clean looking.) The clutch is improved but it feels . . .hmm, not quite right. I guess it is seals braking up. Question is - what next? Any advise on changing seals in these master cylinders? Any clues as to size/ type/ quantity? Answers and tips welcome. Cheers Alan |

O-ring abrasion is the cause of this. The deposit is a fine suspension of rubber dust. It was also an issue with the original clutch masters for sure. I believe the Tazu has been castigated for having similar problems. Over the years, the clutch master issue has been a thorny one and after various ventures away from OEM, the preference seems to have cycled back. At least that's what DMGRS says and he should know.

Thanks T-cut. That was my conclusion.
Tazu did seem to be the saviour of R75 clutches for a brief spell. Shame I've replaced the original pipework with the Tazu copper otherwise I'd have gone for the LHD replacement as your link. Thorny issue indeed. I may approach Tazu and see if they can do an 'o'ring kit. Ta. A |
