try taking your left toe and holding up on the clutch pedal while you apply pressure to the brake pedal.
you see the rod on the clutch master cyl has to be out far enough to allow the fluid to flow (forward to slave cyl when clutch is up)thats what keeps the slave cyl full all the time and allows any air to flow back to the brake master cyl.its self bleeding.so if that dont work then you have to adjust the slave cyl rod end at the clutch pedal so fluid flows when the clutch is out.
let us know
