Wife drives the TB. She has noticed like 5 times now in the last week that when she has the radio on and hit the brakes, when she hits them there is a audible pop coming through the radio. She has noticed when playing FM radio , don't know if it does it while using blue tooth or other methods of playing music.

There is a switch associated with the brakes that makes a "click" noise when depressing the brake pedal. Is that perhaps what you're hearing? Or is it definitely coming through the stereo?

Wife says it is coming through radio system and is loud. I have not driven it to see if I hear it. She says it is like a POP noise.

Our brakes are electric "brake by wire" with a vacuum pump for assist instead of engine vacuum so it sounds like the radio is picking up interference from the brake system. I'm curious is if happens on AM, FM and what frequency?

Wife says she is listening to FM radio. Seems only to do it when putting car into gear or park when you hit the brakes and move shifter lever at the same time. She says it has not done it in just stop and go driving.
