Abstract
A stationary disc for use in a wet disc brake assembly includes a plurality of holes drilled through the disc. The holes change the mass of the disc, and thus change the frequency of the entire disc brake assembly. This portion of the invention is particularly useful to modify the frequency such that it is not approximately equal to the frequency of an associated stationary member. In addition, the holes may be plugged with a material that becomes viscous at expected operational temperatures of the brake. This is valuable to provide a vibration dampener, that inherently becomes actuated when the brake heats.
