Chris Already had the larger radius quadrant fitted....it was the replacement one (now junked in favour of the original) that resulted in complete failure....whilst the larger rad one does make the cable "shorter", more importantly, it gives more travel of the cable for a given pedal movement. End of the day, the bite point is just very low....whether this is due to a problem with the clutch itself or the pedal box as it's fitted to the Quantum I don't know but I suspect the latter as it seems like a very common problem. I think that the pedal is actually bottoming out on the carpet but I can't really see if it's hitting the floor before it hits the stop on the pedal box but if so then that would certainly explain it (different floor shape in the Quantum to the Fiesta maybe?) Anyway, filing the adjustment point tab on the pedalbox seems to have done the job
