Grinding noise on cold start (felt in brake pedal)
 

I'm hoping this is the right subforum for this but my 2005 sedan has an odd grinding noise when first started. It can be experienced audibly and with a rumble in the brake pedal once the car hits ~1600 RPM (this happens in both 1st and 2nd gear).

Any insight would be greatly appreciated.

Video is here and can be heard around the 7 second mark (sorry for the keyfob hitting the steering wheel noise in there as well).

I can't watch the video, but I think you mean the abs readiness test? It happens when pulling away after you put it in drive.
