2013 rav4 makes some strange (groan) noise, as car comes to stop or as I release the brake slightly.
Sounds (and stops) come very rough if car is on downhill and are not smooth.
Definitely something caused by metal friction but nothing like worn pads scratching/squeaking (pads are new, but not sure about quality).
Here are the audios:

Any ideas whats the cause?
