The older models of the Elise S1 were equipped with a aluminium bush which was pushed in the clutch pedal and operated the pushrod of the clutch main cylinder. This aluminium bush worked fine to a certain degree but was certainly not up to the job. Quite a lot of owners started complaining about a creaking clutch pedal. Some even experienced that the clutch pedal didn't come back when the released their left foot from the pedal! The reason for this is the aluminium bush slowly 'eating' it's way into the clutch pedal and vice versa. WD40 doesn't work here and if you wait too long, too much of the inside of the clutch pedal will be removed and even this bush&Trunnion kit will not fit anymore (!)

This kit will replace the aluminium bush and will permanently solve the problem.
