Product Description

?

This set of two carbon brushes is a genuine Makita replacement part, packaged in an official Makita retail box. Each brush includes wire leads and attached brush springs, and is designed to restore optimal performance in compatible Makita tools. Carbon brushes are among the most commonly replaced components in power tools, as they gradually wear down through friction and regular use. Worn brushes can lead to intermittent motor function, reduced power, or diminished electric braking. Replacing them can resolve these issues and restore proper motor performance. Signs of wear include brushes worn near the wire lead, or those that are cracked, pitted, or burned. When replacing carbon brushes, it’s also important to inspect the armature for any signs of damage, such as burns or cracks, which may indicate a more serious motor issue.

Umm.. That wrong part was sent by mistake? Not the Carbon Brush set. Another part. Not sure. Def wrong part, but mistake.
The parts we received in good shape, but a bit slow. Maybe cause of the holidays. Also, I received one of the parts incorrectly. Could of been an honest mistake. Wrong numbers posted. The representative at eReplacementParts, was AWSOME!! super helpfull. Great Customer service. Thanks.

It does what it does.
It's a carbon brush. One got old. I bought a new one. Inundating my email over and over for reviews and technical details is more annoying than helpful. There is nothing you can do to inflate the quality or relative importance of a motor brush. If you need one, you buy one. I like eReplacementparts well enough. Don't spoil it.

I removed the screws from the switch handle, and separated it. Removed the cord clamp. I then made a wiring diagram of the switch and all parts connected to it. Installed the new switch per the diagram, replaced the cord clamp. Made sure all the internal parts were in their place. Then assembled and the handle assembly. For the brushes I removed the brush caps, then removed the worn brushes and placed the new brushes into the brush holders, then screwed the brush caps back on.
