Carbon Brush Set Makita CB-155, replacement motor brushes, 2 pieces

Replacement carbon brush set Makita CB-155, consisting of 2 pieces, is intended for restoring electrical contact between the commutator and the brush holder in many Makita power tools. These replacement motor brushes are manufactured to match the shape and electrical characteristics of original-equivalent parts, allowing reliable current transfer and stable motor operation when worn brushes are the source of sparking, loss of power, or intermittent operation. The set is compact and supplied as a pair to service both brush positions in most two-brush motor assemblies.

Advantages

The carbon brush set provides consistent electrical conductivity and low contact resistance, which helps reduce arcing and maintain motor efficiency. Designed for direct replacement, the brushes fit typical Makita brush holders and come with flexible lead wires for straightforward connection. Replacing worn brushes with this set can extend the life of the armature and restore rated performance without requiring major motor repairs.

Suitable for

• Repair and maintenance of compatible Makita electric drills and saws
• Workshop servicing of handheld power tools with two-brush motors
• Professional tool maintenance and field repairs

Key specifications

• Quantity: 2 carbon brushes
• Material: carbon/graphite composition suitable for commutator contact
• Connection: flexible lead wires for solder or clip attachment
• Intended use: replacement brushes for two-brush electric motor assemblies
• Fit type: direct-replacement form factor matching common Makita brush holders

How to use

Before replacing brushes, disconnect the tool from power and remove the housing cover to access the brush holders. Extract the old brushes from their holders, noting orientation and connection method. Install each new carbon brush into the holder, connect the lead wires as originally fitted, and ensure secure mechanical seating and electrical contact. Reassemble the housing and test the tool under light load to confirm steady motor operation and absence of excessive sparking.

Usage recommendations

Check brush length and replace both brushes as a set when either shows significant wear. Inspect the commutator for grooving or pitting and clean or service it if necessary to ensure optimal brush contact. Use this carbon brush set for routine maintenance intervals or when signs of reduced motor performance appear.
