• Worn brushes are often the cause of a poorly running motor
• Replacing brushes can fix an intermittent motor
• New brushes can restore a motor’s electric braking


Carbon motor brushes are one of the most commonly replaced power tool components.  Because carbon brushes are wear items, meaning that through friction and use they will gradually wear away, they will eventually require replacement.  Worn brushes are common causes of intermittent motor function, reduced electric braking, and reduced motor power.  A worn out brush will often be worn down near the wire lead and may be cracked, pitted, or burned.  When replacing carbon brushes, be sure to also inspect your armature for burns, cracks, or other damage which indicates a larger motor problem.

Drill stopped turning on when power was applied.
First I checked power to the trigger switch, which was good, second I pulled one of the brushes and saw where they were almost completely gone. On this drill you just remove the brush caps with a flat head screwdriver, then reach in and pull out the brush retainer with needle nose pliers, put the new brush in, then screw the cap plug back in.

Drill arched at motor brush area, stopped operating under load. One of brushes was pitted vice smooth. Marita 1/2 inch drill is 20 years old.
Removed brushes with screw driver. Went online, looked up Drill model, ordered brush set. Parts arrived in 4 days. Installed new brushes. Tested drill. Works perfectly. This is a very heavy duty drill, which I use for drilling concrete, mixing paint, mud, and mortar in small quantities.
