While bedding the brakes I noticed that if I let ABS kick in for a while e.g. hard brake from 200kmh to 30kmh, then the media player and connections to iphone restarts. I initially thought that's because of iphone cable and vibrations but it looks like that's not the case. What can be the reason for this? Is it maybe battery cannot provide enough power while braking? Is this something to be concerned about or just a regular behavior?
