It's the nature of a carbon brush that it will eventually wear down after "X" hours of use (they're designed to do so). While I can't speak specifically for the Makita, I've never seen an "undesirable effect" from replacing motor brushes, and I've done hundreds over the years. As long as the correct brushes are used the only problem would stem from incorrect disassembly/assembly.

How much is the motor brush? Anway?(Lowes,HD)
In speaking the Makita service center here in Mississauga, ON.
99% of all their services to the 9227 is from the Marble/Granite installers! Due to all the dust and hard use that the contractor's put it through, it requires servicing quite a bit. However, if they simply blow them out with compressed air, the service number would be greatly minimized.
They rarely repair one from the Automotive industry. The one's they due are typically detailers who use wool pads a lot and the little fibers get drawn into the housing; which leads to a lot of heat and premature failure. If they simply blew some compress air into the unit every once in a while, there wouldn't be a need to ever service it.
It's pretty much a tank for how the majority of users on this board detail with it.

Are we talking about the brush that in the body part...not inside the motor. That little knob on the size, where u can turn with a flat head screw driver? I want to make sure that's what we are talking about.

Correct me if I, and klnyc are wrong, but I think they are the motor brushes.

those are the motor brushes. Yes they may need to be changed but I don't think you'll have to change them. I used to race elec. RC cars and changed brushes when i needed a change in proformance. We had slotted cot and a bunch of other designs for brushes.

I've done 100's of detailes and never replaced any brushes. When the machine stops working right I will look at that maintenance stuff.

Hah, I was talkin' about the carbon brush...I guess mis-understood you guys. So, how long this "carbon brush" before it wear out?

The carbon brushes are the motor brushes. If you look at the page you mentioned, notice that they have a "wear mark" at which point they recommend replacing them. Since your Makita is new just take one out and measure it, then check it again next year to see how much it has worn down. Unless you are a pro using this on a daily basis my guess is you may never have to replace them.

Yup, I took it out. I guess this will last pretty long time.

Wow! Any plans on getting it fixed or switching to another model? Maybe something like a Dynabrade or Metabo?imported_themightytimmah

I bet its just the cord Sean, the machine should last a lot longer than that. Even if it is something else, you might get it repaired for free if you're lucky. Makita has a great dealer network, I have two dealers within 20 miles. That was one of my biggest considerations in picking it over a Metabo or Fein. That, and the bale handle.
Problem Fixed!
I went to the Makita dealer which is ~5 miles from me. I told him the problem and he told me it would be about 3-5 weeks to fix it!!! With the problem in mind, he said its probably the cord. I bought a new cord for $16.30 and was a bit unhappy it wasn't a Makita OE one. The plug for the wall was brass coated, not stainless, but oh well, it never sees the weather.
I came home, opened her up, and installed the new cord. I prayed as I walked to the outlet, plugged her in, and, well, the rest is history. Everything works great. I guess the old cord was just fatigued from heavy use

Wow! That's really great you are handy and are able to reinstall new cords. Hope you see plenty of use. :up
I asked the dealer of Makita (I have a 9227C) He told me it should serve pro detailers for about 1500 hours before any check and control. For amateurs like we mainly are, he said it should be no less than double that, regarding that we do not put loads on it for so long and so frequently...
