Common problem, there's a plastic bush that the pedal pivots on. One or two on here used to sell them I think but also seen them on ebay. Also get underneath and check the slave cylinder is not leaking and also the condition of the flexi hose. Get someone to press the pedal whilst you watch the cylinder and the hose as the hose can balloon too. Keep your fingers out the way thou as you don't want to trap em. There's also a clutch damper pipe runs from the slave cylinder to above the rear axle as that can leak.
If all that helps you, pay ya tenner for full membership :thumbs
