suprised nobody has mentioned wet-dipping as part of the running in process.

New brushes never match the exact curvature of the comm, so break-in is very important for max performance.
2-cells (~3v) run over top a fan is the best way to break in a motor (to keep it cool). If the brush hoods are well aligned, it should take less than 10 minutes. Periodically stop the break-in and check the faces of the both brushes. You only need run them in until the entire face of the brush is making contact with the comm. If the brushes are serrated, only run them in until all the serrations are touching the comm.
Water dipping is really only for silver can motors that have extraordinarily hard brushes. The water softens them allowing them seat fully in a very short period of time.
