The booster brakes were designed and intended to be used with the double puck brakes on the larger diameter tires. The larger diameter tires have a greater leverage against the brakes thus need a higher pressure. The stock Scott bladder master cylinders provide adequate pressure for the 8:50-6s. So when the booster are used with the smaller tires, they are the equivalent of using boosted power brakes. Very touchy. Many a foot which is used to pushing hard on the old brakes (including airliner brakes) has bent a prop with the booster master cylinders.There is a huge difference between the behavior of the brakes with 31" Bushwheels and the smaller 8.50x6s. The brakes seem fairly optimized for the larger tires, and feel right. They are extremely touchy with the smaller tires, and minimal application is necessary or they completely grab.
