As the title really.
I`ve just come back from a whizz around in the MK2 and 7 miles in the clutch pedal feel a bit strange along with a stiffening of the gear change.
I gave it a good ignoring and gave the throttle a blip that seemed to improve the gear change.
On getting home and having a quick look at the pedal I found the clevis pin and R clip on the rubber matt.
I have never used R clips on the brake master cylinder but I know a lot of people do but I did use one on this clutch cylinder through laziness as it seemed too short and stiff to be able to be popped off but there you go.
So if you have R clips now might be the time to put a split pin back in.
