Vermont CDL Air Brakes: Air Brake System Parts Test 2026

Knowing every part of an air brake system by name and function is non-negotiable on the Vermont CDL exam, and this air brakes system parts test covers the full list from compressor to brake chamber. That includes the air compressor, air tanks, the governor that controls when the compressor cuts in and out, safety valves, and the various lines that route pressure through the whole rig.

This system parts test also covers the alcohol evaporator that helps prevent ice in air lines during cold Vermont winters, the drain valves used to remove moisture from tanks, and the relationship between the primary and secondary tanks in a dual system. The Vermont DMV expects a working knowledge of how these parts connect, not just a list of names memorized in isolation.

Run this air brakes system parts test until you can trace the path of air from compressor to wheel without hesitation. Vermont CDL drivers who know their system parts cold are the ones who can talk through a problem with a mechanic instead of just describing a warning light.
