Absolute noob question...
For months my brake lever hadn't been returning to it's proper position. Assumed this was because the cables needed changing.
Did this and it didn't work. However, I loosened this screw, that holds the whole assembly together, a touch and covered it all in GT85 and it seems to be working okay now.
If I tighten this screw back up then the problem re-occurs, so I need to leave this screw not entirely tightened.
It is all going to fall apart while I ride down Denmark Hill and result in my premature death?
