Here's a weird one. Can anyone explain this?

My brakes for the last 3 months or so have developed a chatter while braking, especially at highway speeds. Because it's very minimal at slower speeds I haven't done anything about it. It is a pulsing feel, most likely a warped rotor. I just replaced my pads less than a year ago, and I don't want to replace just the rotor, so I'm waiting until the pads are shot and then I'll replace pads and rotors together.

Anyway, last week I installed energy suspension motor mount inserts.

Get out on the highway, hit the brakes, and the braking chatter is almost all gone! This doesn't make any sense to me.

Unless, maybe the brake pulsing was rocking the whole engine in its mounts and was maybe near a harmonic frequency at that speed to boot? Or is that crazy talk?

hitting the brakes and the motor rocking sound feasible, but to me it sounds more likely that the harmonic vibrations from the motor are being forwarded to the chassis and are overpowering the brake chatter ;)
