North Carolina CDL Pre-Trip Inspection: Brake Check (incl. Air Brakes) Test 2026

Every pre-trip inspection ends with a brake check, and this North Carolina CDL pre-trip practice test for 2026 makes sure yours is complete. On an air-braked truck you build pressure, then test the low air warning, the point where the spring brakes set, and the air-loss rate with the brakes applied. On a hydraulic system you pump the pedal and hold it to feel for a leak-down.

Questions cover the order of the brake check, testing the parking brake by tugging gently against it in gear, and confirming the service brakes stop the truck at low speed. The brake check is a graded part of the pre-trip inspection on the North Carolina CDL.

The number of pre-trip questions varies, so check your North Carolina CDL Manual for the exact count rather than guessing. Drill this brake check practice test until you can run the full sequence from memory before your 2026 exam.
