Lots of times over the years. Used to be someone here that did it, but those days have passed - search on: abs pump motor rebuild ...or just... abs pump motor
Basically it involves:
- Removing the unit from the car and the pump from the unit
...don't break anything...
- Rebuilding the pump by cribbing in fresh brushes and end seal
....end seal must be EPDM, brake fluid safe - searching here should reveal a part number for a honda seal that some have had luck with
- Reinstalling the pump to the unit and the unit into the car
...pump end drive needs to be indexed; best to bench bleed before installing...search here on that process
Good luck.
