eyop discogadge!
I yint bin funny ere, but i did my clutch at crimbo, bled it all wer fine,
till a week later then i progressivly had no pedal after a couple o days. It dunt lose fluid, but never felt quite rite unlessyer doubled the clutch pedal, Its had a liter an a arf of fluid thro it, but ive never noticed any air present when bleedin it. but it seens t have the same symptoms as yours,lots of pedal movement befor you feel any clutch.
last weekend i dint use it for four days an when i went to use it NO FOOKIN PEDAL ! bled it agen an a load o browny black ****e came out,
its bin ok ever since !
keep bleedin it !
