Belt sander Brushes

[chunkolini]

My big old Makita Belt sander (9404) suddenly came over all feeble the other day.
Would not switch on and when running felt like a silver line toy.
I guessed Brushes. Took them out. One is twice the length of the other so they are worn.
it has come back to life now but I figure best to replace them.
I cant see makita ones to fit and there are umpteen makes at various prices.
Are they much of a muchmess?
The originals have gone one for well over ten years.I'm happy to pay more for genuine.
But are they just a bit of pencil lead on a spring really?

They are part number 15 on the exploded diagram and are type CB-303.

If you search for CB-303 brush, there will be lots of options, genuine and third party. For something like that, a large proportion of the cost to you will be in the postage the seller requires.

It might be worth writing down the brush spec. somewhere inside the casing.

Cheers all.
That was painless. I went for genuine ones in the end.

Just be aware that not all brushes are the same…

Brushes even the same size, made for a low voltage power tool, may have a high copper content to carry the current….

brushes have diffrent grades of carbon some are harder than others older powertools had harder copper segments on the armature and used harder brushes. modern armature copper is soft so if the brushes are too hard it wears the armature down rather quick
