A method of attenuating audible sounds generated during a brake application through the engagement of a friction member (10, 30) with a rotating member. The brake is evaluated by modal and frequency response analysis to determine the natural frequencies generated during a brake application and identify the natural frequencies that create audible sounds. The locations on the friction member (10, 30) are identified which are most sensitive to generate audible sounds. Thereafter, portions (12-18, 32-54) of the friction material at the most sensitive locations are removed to change the natural frequency and attenuate the development of audible sounds.
