Back in the eighties, when every taxi in Montreal was a diesel jetta, we would change old clutch cables to the self adjusting ones. Would make the clutch last twice as long, if not even longer.
If a clutch wasn't grabbing 100% , it wouldn't last very long
The clutch cable is one of the 1st things I do when id get a "new" car.And I always have a spare.I had a cable snap on me when I had a volvo 240, had to power shift most of the way home until I hit some traffic.Pushing a giant steel brick by yourself in the rain in rush hour traffic is not a good time.I now have a spare cable in the trunk of my mk2. Just in case...
