#1 Clutch - low biting point

Post by ChrisC » Tue Jun 30, 2026 10:49 am

The clutch in my car was replaced and has only done 3000 miles. The other day I noticed that suddenly the biting point was only just above the floor as opposed to its usual 1/4 way depressed. I figured this might be because of air in the system / a faulty slave cylinder (as I seem to go through these).

Cutting to the chase - I have replaced the slave cylinder AND the master cylinder - I have decent pedal pressure but the biting point is STILL just off the floor so I am thinking the issue is not hydraulics and I am getting a little frustrated.

Any suggestions good people as to why the clutch might do this after a 6 month layup?

I had the same issue with my MK2 after just 600 km. The cause was the graphite release bearing, which had literally disintegrated. It was a brand-new part from SNG; I mentioned it to them, and they told me they’d had a defective batch but couldn't replace it under warranty since I’d bought it over a year prior. Well, it’s not the cost of the bearing itself, but the labor involved in taking everything apart again...

You can look up into the bell housing through the hole in the bottom and take a photo of the release bearing to see if it is intact. I have never heard of one breaking up but they can wear out verry fast if not adjusted properly and are dragging.
