Carbon motor brushes (carbon material) with wire leads and brush springs attached Function: Conduct electrical current between stationary and rotating parts of a motor to ensure proper operation and electric braking. Key components included: carbon brush block, preattached wire lead, and brush spring for immediate installation. Why you need these brushes Fix poor motor performance: Worn brushes are a common cause of motors that run weakly, sputter, or lose power. Restore electric braking: Replacing worn brushes can restore a motor's electric braking performance. Solve intermittent faults: brushes can eliminate intermittent operation caused by poor contact. Important specifications Material: carbon Size: 36 x 12.5 x 5 mm (measurement excludes collar) Configuration: wire leads and brush springs attached Compatibility: designed for motors that accept 36 x 12.5 x 5 mm carbon brushes (excluding collar). Please confirm this is the size you require before ordering. Performance benefits Reliable electrical contact for smoother motor operation Quick replacement with included spring and lead reduces installation time Helps extend motor life by restoring correct brushtocommutator contact Typical use scenarios Repairing a power tool motor that runs unevenly or stalls Replacing worn brushes in household appliances or workshop equipment to stop intermittent failures Restoring electric braking and control in small electric motors used in DIY or light industrial applications What to check before Verify your motor uses carbon brushes of the listed dimensions (36 x 12.5 x 5 mm excluding collar) Confirm whether your motor requires brushes with preattached wire leads and springs If the size and configuration match your motor, these carbon brushes provide a straightforward way to restore reliable operation and braking performance.
