As the bike slows, lever pressure should be gradually reduced. Say a rider applies 1 lb. of force to the lever at 20 mph to get a given deceleration rate. It takes 4 lbs. of pressure to achieve that same rate at 40 mph. And at 80 mph, it takes 16 lbs. To brake effectively from 80 mph to a stop, the rider needs to apply 16 lbs. of lever pressure at 80, easing to 9 lbs. at 60, 4 lbs. at 40, 1 lb. at 20 and almost no pressure at full stop. How do you keep the front wheel from locking up? Why does it lock up at all?
