It is always best to replace both brushes, even if only one is worn.

Worn brushes frequently are the cause behind a motor running poorly.
Replacing brushes can fix a motor that’s operating intermittently.
New brushes can restore a motor’s electric braking.

Carbon brushes are one of the most commonly replaced power tool parts. This is because carbon brushes are wear items, meaning that through friction and use they will gradually wear away until they need replacing. Worn brushes are a common causes of intermittent motor function, reduced electric braking and reduced motor power. A worn-out brush will often be worn down near to the wire lead and can be cracked, pitted, or burned. When replacing carbon brushes, be sure to inspect your armature for burns, cracks, or other damage which can indicate larger motor problems.

There are over 120 tool that use this brush.

The carbron brush was worn out.
1. Remove housing around top of motor by unscrewing screws with a power drill to speed process. (Screwdriver is suitable but slow)
2. Note the position of the power button and lock mechanism for proper orientation upon re-installation.(Taking a pic with my camera on phone is helpful if no schematic is available)
2. Once exposed I removed carbon brushes from seat with needle-nose pliers. The brushes are held in place with wind-up springs and require a small screwdriver to relieve the tension on the brush for removal, a delicate touch is required.
3. Installation is reverse of removal.

Repair Difficulty:
Medium
Time Spent Repairing:
30-60 minutes
Tools Used:
Screwdriver, Pliers, soldering iron, heat gun
Wiring from field winding on motor to control board was broken at the connector
1. Replaced brushes based on device failure symptoms and repair recommendations.
2. During brush replacement, noticed wiring/connector connection from field winding was barely making contact.
3. Spliced old brush connector onto field wiring. Blade connector (blade type) used in field wiring is not easily obtained, so reused brush connector. Brush connector was the same connector used by the field winding.
4. Used heat shrink tubing to insulate splice.
5. Tested sander for proper operation.

Sander quit running
Removed the top cover after unplugging. Noticed brushes were very short so decided to replace to see if this is the issue. Dust cover was compromised so that was a no brainer.
New brushes were very long, installed easily and it all went back together and ran perfectly.
