No expert...but could it be leaking out the master cylinder? Had a car once that was doing this..turned out it was being sucked into the vacumn booster and into the engine.

Check under the dash, could the fluid be leaking to the interior somewhere?

Also saw on another thread here that some cars share the hydraulic resevoir for brakes and clutch. Manual trans? Hydraulic clutch?

Just some thoughts til a Pro shows up....

Is it possible for the proportioning valve on a elantra to leak??I have changed master cylinder and 1 wheel cylinder on sons car but he still has a fluid leak some where.Hand has come away wet with fluid after rubbing bottom side of proportioning valve but am not sure if this is from overfilling fluid and spilling some in master cylinder bowl,car loses about 100 ml of fluid every day or 2
