I had a similar issue with the left rear caliper, fixing it increased (restored) coasting distance by a noticeable amount.
As you've found, the front wheels are hard to test due to the drive line drag.
I lubricated the front to be sure but noticed no improvement.
If you have access to a non-contact thermometer, check rotor temps after driving.
There should be a big difference in temps if the brake pads are dragging on any wheel.
