DeWalt DWD112 Brush Replacement

The brushes in the DeWalt DWD112 direct the flow of current to the motor and create power for the drill. They can wear out over time, causing the drill to fail.

Worn out brushes can be replaced with a few easy steps. It is not necessary to remove all of the other parts for this repair, but it is advised as to not damage the other components.
