• 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.

Questions & Answers

I have a very old Makita belt sander. Serial number is 275048E. The online instruction manual says replace carbon "brushes." But I only see one brush cap on this old model. Are there two on newer models?

Worn out brushes, brush cap broke on removal
Makita 9217SPC, variable speed sander polisher. this is a high mileage tool that is heavily depended on in my occupation as a professional boat builder. This tool functions primarily with an eight inch pad and very typically 36 grit for shaping in the rough prior to the application of fiber glass, and again after the application of glass. I have had the tool for 12 years this was the eighth set of brushes I have installed. I cross threaded the brush cap while inspecting the brushes, which created the problem of finding an extra brush cap. Removal of the cross threaded button required the careful destruction of the same. I am thankful that e replacement parts had those brush caps available and in stock as I am extremely attached to that old sander and although I have the newer model that's 2 years old there are a few ergonomic differences and I prefer the older model..... Thanks again.
All you need to do is remove the brush cap and take out the old brushes and put in the new ones , then put the brush caps back on.

    Right product with fast delivery
    The correct part was shipped and delivery seemed like next.day. The only problem was the cost of shipping was as much as the part.. That is why one star was deducted from excellent performance.
