ABSTRACT:
A device for reducing the level of brake squeal noise having a damper ring disposed between a brake drum and a vehicle wheel rim where one or more friction springs extend from a retention band to form the damper ring with its axial position relative to the wheel set by a stop flange attached to the retention band and where the friction springs contact the squealer band of the brake drum with a separation force thereby creating friction damping on the squealer band to lower vibration and resultant noise levels produced by the brake drum.
