Re: [Chrysler300] Anti chatter springs

I understood they were put in to prevent squealing — story back in the  day .those brakes often were loud.  I often wondered how they did effectively did that . Maybe friction between drum and spring damps high frequency vibration , like those devices you sometimes see on utility wires in air. Some of those look
Like springs . The wires  vibrate and fatigue at the pole end fastening , eventually breaking off . Cannot believe it does anything for cooling the brakes ? Thermal connection to drum bulk metal too poor?

The springs must be for additional cooling since they add cooling surface—nice to have in heavy braking but not essential in “normal” driving.

Over the past 40 years I have found drums with them missing and have had a few break from rust.  Didn't seem to make a difference if the shoes were matched to the drums and all lube surfaces were rust free and greased.
