Have found a cure!!! See link here . . . clicky
Undo the little clip that holds the rod from the master cylinder on to the pedal. Move said rod to one side and then:-
1- Insert thin rubber tap washer on the inside edge of the bar that connects the pedal to the master cylinder
2- Put lithium grease liberally on the part of the clutch pedal that goes into the master cylinder rod eye
3- Pack the inside of the hole on the master cylinder rod with lithium grease too
4- Lithium grease the two outer faces of master cylinder rod and re-attach to clutch pedal
5- On the outermost side under the wee clip you should have removed a small washer. This is too small and next to useless. Replace said washer with something of bigger diameter (apprrox 25-30mm) remembering to lightly grease the inner face too for good measure.
6- Now put the wee clip back in.
This should take no more than 10 mins tops and has worked for me having had a silent clutch pedal now for three weeks. It doesn't however cure the occasionally notchy travel but that is for another day. It is my opinion that the creak is caused by a bit of lateral movement of the slave cylinder where it attaches at the top of the clutch arm, which accentuates the wear. With the tap washer, the greasing and the bigger washer holding it together the whole assembly becomes more solid.
Hope you can decipher my ramblings, if not don't hesitate to ask. Hope this is of some help
