Been looking back through some older posts. I found this comment from Nelly in 2008:- "I've lost count of the number of slipping clutches and binding brakes that have been down to patterns causing pump up's in the master cylinders. Clutch you can live with, but if the brake pumps up..... then you'll lock the wheel." Can someone explain please what "pump up" is and why this could happen with pattern levers? |
