I recently pulled up the carpet to hoover and noticed the centre bolt of the three clutch pedal inboard housing bolts appeared loose, it was a few threads proud of the housing block. Check tightened and it is tight. I think the bolt impinges on the shaft to prevent the shaft from rotating. Using good engineering practice when finding a loose bolt I checked the bolts either side. The aft bolt is tight but the forward bolt rotates and does not feel like it is connected to anything. I did not have time to investigate but thought I would check to see if anyone has experienced similar before pulling out the clutch pedal to see what has happened.
