Hi Trevor. As you say, the switch doesn't have any direct bearing on the bite point but my experience of driving with it both fitted and disconnected is that there has been a definite alteration in both the bite point and the amount of grab it provides. Might be just a one off on my vehicle as I note the pedal rubber is well worn on the left hand edge indicating that the previous owner liked to drive with a foot resting on there. I may just be undoing some of the polish this may have put on the plates.
