Carbon Brush for Makita BO4553, BO4554 Sander

The Makita 194968-1 Carbon Brush (CB-64) is a genuine OEM replacement electrical contact designed to restore motor performance in compatible Makita finishing sanders, including the BO4553 and BO4554. Carbon brushes transfer current to the motor's commutator, and as they wear over time, tools can become intermittent, noisy, or underpowered. Fitting a fresh brush restores consistent power delivery, reduces sparking, and helps protect the armature from unnecessary wear. Manufactured to Makita's original material specification, this brush uses a high-quality carbon grade formulated for balanced conductivity and controlled, predictable wear. The stable contact minimises arcing and heat build-up at the commutator, supporting smooth start-up and steady speed control during use. This is an ideal maintenance component for tradespeople and contractors carrying out scheduled servicing or fault-finding repairs on site or in the workshop. Straightforward to fit using basic hand tools, it reduces downtime and extends the working life of the tool without the cost of a full motor replacement.
