Master and slave were both replaced about 20K miles ago (in 2002) by Mazdatrix.

Currently niether appear to be leaking. Master is definately not leaking. The clutch was working fine but fluid was nasty so I flushed and bled the clutch with Super Blue fluid.

Clutch felt better, the engagement point got higher off the floor a bit and everything was fine, but it started eating fluid. Reservoir would go from full to half in a couple hundred miles.

At a track day a couple weeks ago it seemed to level off and we didnt have to add any fluid (I didnt check the clutch fluid on my way home, but the clutch was fine) The car has sat for a week, but I have driven it a bit since the track day. This morning the reservoir was empty and the clutch didn't work when I tried to drive it. I poured more fluid in and now the clutch works fine again.

There is no evidence of fluid leaks anywhere on the car or on the ground. I have probably poured 4-6 oz of clutch fluid into the car since I bled it.. where could this be going? I suspect if something is bad, it could be the slave, but I don't know for sure.

Thoughts? I don't there there is air in the system but should I try to rebleed it?

 

Look up into the footwell...it's probably leaking down the firewall and behind the carpet.

 

I did.. clean and dry. The master is 100% dry inside and out which leads me to think it is the slave.. but it is dry there too from what I can see from the top, and there is nothing dripping on the ground.
