Dropped an 18V DeWalt grinder from a ladder top and it broke in half tearing the lead out of one of the brushes. Brand new grinder. All I had to do is pull the solder-less connectors apart, pull the clip that holds the brush back and remove the brush.

removed the outside covers, exposing the motor. Used a jewelers screwdriver to holdback the brush retention spring and removed the old brush. Be sure to remove all pieces, I used tweezers to pick little pieces that were jammed down in against the motor and canned air to blow out excess.

Once it is properly seated, disconnect the old brush from the wire and connect the new brush to the wire connector. Repeat for the opposite side. When I got both new brushes installed, I set everything in one of the covers and inserted a battery. Be CAREFUL, carefully engage the trigger to see if you got the brushes inserted properly (curve the right direction). It should work with minimal sparking, if you have a lot of sparking there is a problem. If it is both, pick one and turn the brush the other direction, reinstall the battery and try the trigger. Is it the same or is one small sparks and one large sparks. One small and one large, turn the large one around and retest to see if both small. Small means the tool will not get hot in your hands. If it is large, I would remove the brushes and check for missed debris and check the brushes for damage and even swap them from one side to the other. If I could not get small sparks, I would put it together and use it for a couple of times, nothing too rough, then open it up and check the sparks. If still large, I would remove the brushes and check the contact ends, if it shows any irregular wear, contact a professional.
