[Tigers] Clutch slave cylinder - is the bad gunk?

[Mark Rense]

I have rebuilt my share of these using Rick’s (Sunbeam Specialties) kits. Check the interior bore for scratches or chatter marks, clean everything really well with a brake cleaner solvent (CRC red can is my go-to), and use Red Grease to lube the rod where it goes through the outer rubber cover and to pack behind that cover. Most important: clean everything, clean everything again, then check to make sure everything is clean!  

 

Had good results with the new Castrol GT/LMA synthetic brake fluid, seems to swell the rubber seal as well as the old stuff and is readily available. 

 

If you live in a climate that is cold and damp for part of the year, you should replace the fluid in your reservoir every year and flush your hydraulics at least every other year, the master cylinders do not have moisture barriers and that goo you found inside your slave is from water mixing into the brake fluid and the outer grease over time.

 

Welcome to the exciting world of Tigering!

All,

Found my clutch fluid mysteriously gone and this is what the slave cylinder looked like - it had been through a number of hands getting from UK to USA (and coast to coast USA as well).

Is the the gunk which forms when mixing fluids?

Trying to decide exactly how bad my problem is ...

Cheers in advance,
