The carbon brush itself will be housed in a metal slot, and is attached to a clip that attaches to the outside of the slot.

They're also kept in place with a spring loaded clip at the top.

To remove the old brushes, lever this top clip out of the way using a screwdriver, then gently lever the clip off the outside of the slot, and then slide the carbon brush out.

Step 3: Insert The New Brushes

Reverse this step with your new set of brushes, sliding them into the slot, clipping the other part on the outside of the metal housing, then levering the spring back in place.

Step 4: Reassembe The Drill

Finish the process by screwing the back onto your drill again.
