Product Description ?

Genuine Makita replacement part
Set of 2 Carbon Brushes with wire lead attached.

• 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.

    Easy repair
    My grinder works like new again. A friend told me about replacement parts. Thanks
    Brent - February 24, 2020 Verified Purchase
    Very easy to replace and fit perfectly!
    These appear to be the correct carbon brush and the removal of the old ones was easy and installing the new ones was too! A lot cheaper than buying another $90 grinder!

    Armature was missing a big section

    Tool Type

    Grinder

    Difficulty

    Medium

    Time

    15-30 minutes

    Tools Used

    Screwdriver, Pliers, 10mm open end wrench

    Remove grinder head, remove brush cover, (1 screw at cord end) remove 10mm nut from head end. Remove both brushes. Install new armature, install grinder head, install new brushes, install brush cover. After all that, I turned on and it jerked 2 times, tried to start. But failed. I then removed brush cover & inspected brushes. I could see the brush holders were bent, possibly from hitting the old armature section. Slightly adjusted brush holders so brushes would contact armature all the way. Reinstalled & it worked great!
