DeWalt DWE4011 Brush Spring Replacement

Introduction

The brush spring pushes the brush against the armature. The spring can lose its tensioning properties due to overheat. Make sure to always unplug your device before fixing it. Pay close attention to the position of the spring and only work on one at the time (in case you forget how is position you can look at the other one).
