Yes, there will always be some sparks, that is normal. When a new set of brushes are put in, the end of the carbon that touches the commutator on the armature is flat. That surface will quickly wear to the curvature of the commutator. The excessive sparking you initially see is from the brush wearing to that curved shape.
