Hi - just before we start taking things apart due to a creeping clutch - is there any common fault / check to do first?

Basically it is getting difficult (sometimes) to get into gear once hot and a little bit of creep pulling away.

Thanks from the UK

The master cylinder is a lot easier to replace then the clutch slave. If you're not adding fluid to it that's the easiest and cheapest part of your clutch system to replace.
