Re: ford ka clutch problem ?
Easiest way is to top up tank , get someone to pump pedal slowly whilst you open bleed screw on slave cyl . that is after you have fitted bleed tube and immersed same into some fluid in a jar or like . Bleed until clear of air bubbles .Normally when you have to bleed clutch it indicates a leak , possibly slave cyl . if as you say master cyl has been replaced. Hope this helps.
