xsara clutch?

a quick add on to my last post regarding my 2001 1.6 xsara clutch problem,when engine is off it is still very notchty,.no clutch slip at all,no clunks or squeaks of any kind,problem as bad when in motion,can get gears but a real effort ,think its hydraulic clutch,cant seem to find any where to top up fluid ,or master cylinder ,only fluid bottle is the brake and servo bottle.please help ,hoping a top up and bleed of system will cure problem,thanks people
