Clutch Grinding

With all the correct parts and the freeplay set,the pedal I'm guessing, only needs to go down something like 80/85% to achieve sufficient departure, to not have creep.
If you have to go further than this, and the grinding originates in the BH, then you are slamming the fingers into the disc, and it is likely worn out or too thin for the PP. You will have to take it all out.
