The new brushes take some time for the curvature to settle so that it matches the commutator curvature. Often you don't get optimum power out of the motor, and you may have undesirable noises. A little filing or sanding of the brush head edges may help avoid this.

And, you don't necessarily need to replace with any original part, if you're dealing with a 10+ year old machine... I have repaired some several washer etc. motors with car parts. Talking about alternator brushes...
