• 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.

Using a flat head screwdriver, remove the brush caps, then remove the old brushes. You may want to blow out the brush holders and clean the edges of them so the brushes will slide easily. Then install the new brushes and replace the brush caps.

Carbon brushes had worn out. I have had this Makita for 15 years. I was easy to install by taking the screws on one side out, take the two screws for the brushes out and install the new ones.

Tools Used:
Screwdriver
The motor speed varied when the control switch was at high.
Took out the old bushes with a flat screwdriver turning back the covers and replaced with new. The unit performed better but it was not a complete fix. The next step for me would have been to replace the armature so I disassembled the unit with a Phillips screwdriver. Everything looked fine other than a few carbon marks as the old bushes had worn down. I buffed with 320 wet/dry paper and reassembled with the new bushes. Unit is back to 100 percent.

Question: Carbon Brush CB-408

1566894

I have some clients that say that CB-408 is too big for the 9501B power tool. Please let me know if there is any older generations of this power tool that use another carbon brush. Is this the reason that CB-76 is showed as replacement part of this power tool>
Question: Switch Or Motor

duff5110

On my Makita 9910 sometimes it will not turn on when you pull the trigger unless you tap (hit it with your fist) the top of the unit. Then it will start up. What part should I expect to replace? switch/brushes/??
Hi duff5110,
Remove you brushes and look how much wear is left on them.Also with compressed air blow out the brush tubes as often dirt and saw dust will get lodged between the brush and brush tubes and not allow good contact with the armature.But this sounds like a brush problem.Hope that helps. Good luck.

    Great service
    The parts I purchased from eraplacementparts brought my makita beltsander back to life. This was my favorite beltsander and has been a discontinued model for several years now. It's great to have a source for hard to find parts. I'm a woodworker and always have power tool that need repair. I'll definitely be back. Thank you for your help and speedy service.
