BRUSH SET - 4 (Yale YT2121E1057)

YT2121E1057: A worn carbon brush set can cause intermittent electrical contact and eventual motor failure. The Yale catalog reference YT2121E1057 identifies this aftermarket replacement brush set. This set includes four carbon brushes, which conduct current between stationary and moving parts in an electric motor. Over time, brush wear reduces spring tension, leading to arcing and commutator damage. In a typical service interval, brushes are inspected and replaced when they reach minimum length.
