I too was skeptical about this procedure. But give it a try. On my beta it decreased my front brake lever travel by at least 30%. You have nothing to loose and easy to do.
Now if I could only get the rear brake to operate more efficiently I would be happy. Ive done everything to improve its operation. Pads and bleeding. The rotor is slotted. I may try a solid one. Its operation at best is either on or off. My old sherco has much better feel and a solid rotor. Ive rode a 4T and by far the best brakes over all on any bike. And it too has a solid rotor . Am I on to something?
