How to maintain your air dryer: Moisture is your brake system's worst enemy, and your air dryer is its best friend

Ample oil usually is a good thing, but not when it comes to air dryers - vital components that help ensure your brakes get clean, dry air. An air dryer's internal workings would last forever except that oil from the compressor eventually works its way into the dryer and keeps the desiccant beads from grabbing water the way they should. So the desiccant bed and oil separator (if so equipped) have a limited life - normally about one to three years.
