This would indicate brake drag.
Heating the disk or drum on one side causing a warp.
I have this on one side and is a caliper not releasing.
Remember that braking removes/transfers weight from the rear to the front making the rear able to react more to any issue that would cause vibration.
Good luck.
This can also happen if the linings for the drum are mixed and a Left-right lining is installed on one side and a Right-left lining installed on the other. Yes, it is possible to do this. This causes one side to drag more than the other and also shows up when you start the vehicle forward. The one brake is pushing against the drum and the other is free.
