Carbon Brushes
The electric brake relies on the motor's back-electromotive force (EMF) to generate a counter-torque, which requires high-integrity contact between the commutator and the carbon brushes. As brushes wear down or lose spring tension, they can still provide enough current for the saw to run but fail to maintain the low-resistance path required for the high-amperage braking spike. Replacing the brushes restores the electrical continuity necessary for the dynamic braking loop to function.

Trigger Switch
The trigger switch in this model is a dual-function component that manages both the power-on circuit and the 'normally closed' braking shunt. When released, the switch disconnects mains power and simultaneously shorts the motor windings to initiate braking; if the internal braking contacts are pitted from repeated inductive arcing or environmental contamination, the braking loop remains open. This results in the motor 'coasting' to a stop rather than engaging the active brake.
