I have XT 750 levers with the 3 step Servo Wave for tuning the brake action. Each lever has removable adjustment blocks so you can adjust the sensitivity of the brakes. With no blocks removed, my brakes were very hard to actuate and no modulation. With one block removed, they are perfect. Just a light touch actuates the brakes and the modulation is good also. To follow up with what supcom asked, what type of Avids do you have?
