Specifications
  • Brush head: 1/2" x 11/16" x 3/16" Brush and Spring Total Length: 1.5"
Description:
Genuine Makita replacement part
Includes two Carbon Brushes with wire lead attached.

• 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 bought a used miter saw it was working great,some sparking from the motor down towards the cutting head inside the motor housing. One minute it was working then nothing. What would be the cause?
Brian brennan for model number LS1013
Hello Brian, thank you for your question. I would recommend checking the brushes and brush caps. It sounds like the need to be replaced. I hope this helps!

Routine replacement of brushes
The old brushes had about 1/3 of their original length. I removed brush caps with a screwdriver, then used some forceps to remove the worn brushes. Installed the new brushes into the brush holder, then replaced the brush caps. I have used the planer for over 40 years without any problems other than feed roller replacement.

Didn't work
This is on a Makita 3612BR router that was given to me. Checked the brushes, one was wore and the other was gone. Just had to remove the brush caps and clean out the brush holders, then insert the new brushes and screw the brush caps back on. There were some other things wrong like the cord was shot, easy enough to replace. Some one replaced some of the screws with SAE screws instead of METRIC, that was a small fix, tap and die set to the rescue. A good cleaning and it works great.

Circular Saw

Carbon Brush Set - CB154
Repair Difficulty:
Medium
Time Spent Repairing:
30-60 minutes
Tools Used:
Screwdriver, Dremel
Brushes gone
The old brushes were seize into the armature. I did not want to take the armature out of the saw housing. Took a dremel tool and sawed out small holes in the side of the saw where the saw vents are located. Took a small jeweler screwdriver and tap the brushes thru the holes created.. This loosed the old brushes. I made sure everything was cleaned of all carbon. Installed new carbon brushes. Saw now screams like a new one. If your saw is under warranty, I would not do this. My saw was old and I had nothing to lose.

Question: Electric Brake On Makita LS1011N

kjerome

So if I understand how the braking or stopping of the blade from spinning is from reversing the flow of electricity when the trigger is released, correct?

I am rebuilding a saw for my self and replaced the switch however this did not correct the run on, so what should I be looking for. Can bad brushes have anything to do with this?
WJA
Hello kjerome,

If the CB154 brushes are to short that could be the cause of your braking problem. Usually it is the switch, but you have already gone that route. The other cause may be the 596136-6 Field Assembly 115V. It has a winding in it that works with the switch when it is released to reverse the polarity. It might be shorted.

Question: Brushes For 5007nb

1041919

My saw was working perfectly fine. The manual recommended regular inspection of the brushes. I removed the caps, inspected the brushes and there was no wear at all. I replaced the brushes and now the saw will not run. Power goes to the motor, but the blade does not spin. I have removed the brushes and replaced them over and over but to no avail. Same issue. I can hear the motor hum, my workshop lights dim a bit (so amperage seems good), the noise is a loud clunking/grinding type sound inside the housing but the blade barely moves. Can anyone help me?
Hi,
Well I'm confused by the sequence of events.That normally sounds like a spun bearing.With the saw unplugged can you rotate the blade .Are you saying that this problem happened after you removed and reinstalled the brushes.When you mention that the lights dim in the shop it sounds like something is binding up the motor.That would generally be a bearing.Any extra information on the problem would help.

Question: Electric Brake Not Working

wroname

The electric stopped working. Do I need to replace the controller? Thaks
WJA
Hello wroname,

I would inspect your CB154 brushes to make sure that they are making good contact with the armature. If they are okay I would guess that the 651923-1 switch. It reverses the polarity momentarily and causes the motor to brake. Most of the time when the brake is not working the switch is the problem.

-WJA
I inspected my original brushes for this electric brake not working. Th brushes showed very little wear, but when I put in new CB154's, all is well now. I do suggest that to NOT fix the problem of the spinning blade is asking for disaster, not to mention slowing your productivity with the saw while waiting for it to spin down.
My brake quit on my LS1214L a couple years ago. I replaced brushes, I replaced the trigger switch - still no brake. Was told by repair center not the controller. Was told issue was armature. Decided to go ahead and replace. It worked! Such a good tool I hated to lose it for the cost of an armature.
