Air Brake Test Practice

Air Brake Test Practice is a study app for the air brake endorsement, the one added to a commercial licence. 30 practice questions across six topics, a timed mock exam, and a plain explanation attached to every answer. It works offline, in English and in French.

This is an independent study aid. It is not affiliated with or endorsed by any provincial licensing authority, and these are not the official exam questions.

WHAT IS INSIDE
- 30 practice questions, five in each of six topics: system components, how the system works, inspection and leak tests, brake adjustment, safe operation, and troubleshooting and safety.
- Study mode, where you work through questions by topic at your own pace.
- A timed mock exam: 20 questions drawn from the bank, 30 minutes on the clock, and 80 percent to pass.
- An explanation on every question, so a wrong answer teaches you something rather than just marking you down.
- A results screen with your percentage and a review of what you got wrong.
- Full English and French. Every question, every choice and every explanation is written in both.

WHAT THE QUESTIONS COVER
Reservoirs and the compressor. The governor and cut-in and cut-out. Applying and releasing, and what the spring brakes do when pressure drops too low. The static leak test, the applied leak test and why the reservoirs are drained. Slack adjusters, pushrod travel and when a brake is out of adjustment. Safe operation on a long downgrade, why fanning the brakes is dangerous, brake fade, and what to do when the low pressure warning comes on. Water in the air tanks in cold weather. Diagnosing a fault before it becomes a roadside inspection.

WHO IT IS FOR
Anyone preparing for the air brake endorsement on a commercial licence, drivers refreshing before a road test, and fleet staff who want the fundamentals straight.

HOW TO USE IT
Work through study mode by topic until the explanations stop surprising you, then sit the timed mock. Repeat until you are clearing 80 percent comfortably rather than occasionally. The questions are drawn fresh each time, so a second attempt is not the same paper.

A NOTE ON PROVINCES
Where a figure differs by jurisdiction, the question is phrased generally. Please check the current handbook published by your own licensing authority before your test.
