## Long description

Carbon Brush Set Makita M191978-9 (CB-318) contains two replacement carbon brushes designed for use in compatible Makita power tools that require this brush type. These carbon brushes are intended to restore reliable electrical contact between the motor's rotor and the stationary parts, reduce sparking at the commutator, and support consistent motor performance as part of routine maintenance and repair.
Advantages
This set includes two precision-molded carbon contacts that fit the brush holders used in the specified Makita-compatible tools. The brushes are made from conductive carbon material matched to typical commutator profiles, which helps maintain stable electrical transfer and reduce wear on the commutator surface. Installing new brushes can lower motor noise caused by intermittent contact and can help extend the usable life of commutator-driven tools when applied correctly.
Suitable for
 Maintenance and repair of drills with commutator motors
 Replacement in handheld saws and grinders that use compatible brush dimensions
 Routine servicing of compatible Makita power tools to restore motor contact
Key specifications
 Pack quantity: 2 carbon brushes
 Material: conductive carbon composite designed for commutator contact
 Compatibility: made for use in tools that accept this brush type and size
 Function: restores electrical contact between rotor and stator commutator segments
 Typical application: commutator-driven handheld power tools (drills, saws, grinders)
How to use
Before replacing brushes, disconnect the tool from its power source and follow the manufacturer's safety instructions for disassembly. Access the brush holders, remove the worn brushes and inspect the commutator for heavy wear or damage. Insert each new carbon brush into the holder with correct orientation and secure any retaining springs or clips. Reassemble the tool, reconnect power, and run at no load for a short time to seat the brushes against the commutator. If abnormal sparking or excessive vibration persists, stop and inspect the commutator and brush seating again.
Usage recommendations
Use this brush set as part of scheduled maintenance when brush length or performance falls below acceptable levels. Replace both brushes at the same time to ensure even wear. If the commutator shows scoring or out-of-round condition, have it serviced before continued operation. Follow safety and disposal guidelines for worn carbon components.
