Like lots on here, my car had a notchy and heavy clutch.
I got it on 58k miles in December 2011. I have just cleared 105k with very little problems.
Anyway, the one thing that has "annoyed" me about the car was the clutch action.
I burst the master and slave, so replaced them and did the shaft wiggle/oil/lube thing.
Still the clutch was a bit notchy and the action not smooth.
A couple of weeks ago, the pin that holds the master cylinder onto the clutch sheared and the master cylinder rod popped off the pedal.
I had a look and noticed that the pin had been catching the rubber bush. Now I dunno if there should have been a washer at the end to stop the pin catching the bush, but there wasn't one when I changed the master all those months ago.
I slid the master back onto the pedal and watched the action as I pressed the pedal by hand. I could see that there was a slight jerky give in the bush, like the metal sleeve was catching on the pedal bit.
So I popped it off, put some copper grease on the shaft, a little on either side of the rubber bush, slid it together, put a big washer on the end and used an "R" clip to secure it all.
Sorry for the long post, but 2 weeks on, the clutch action is still light and smooth. I can only guess that the notchyness I have always got was from the pedal/master assembly catching.
I still have the old master and checked that. Yes the rubber bush and been torn slightly by the pin.
I hope this maybe helps a few others to get rid of the notchy clutch pedal.
