  1. How vehicle brakes work · Stopping a vehicle

    Stopping a vehicle — key rule 1

    Brakes stop a vehicle by pressing shoes or pads against drums or rotors; the friction turns the vehicle's motion into heat.

  2. How vehicle brakes work · Stopping a vehicle

    Stopping a vehicle — key rule 2

    Too much heat causes brake fade, brake failure and even tire fires.

  3. How vehicle brakes work · Stopping a vehicle

    Stopping a vehicle — key rule 3

    An overheated drum expands and can move away from the shoe so the brake no longer contacts it.

  4. How vehicle brakes work · Stopping a vehicle

    Stopping a vehicle — key rule 4

    If brakes overheat from overuse or poor adjustment, stop, let them cool and check all brakes and their adjustment.

  5. How vehicle brakes work · Stopping a vehicle

    Stopping a vehicle — key rule 5

    Make sure brake parts are cool to the touch before taking any measurements.

  6. How vehicle brakes work · Stopping a vehicle

    Stopping a vehicle — key rule 6

    One malfunctioning brake makes all the others work harder, so they overheat and may fail too.

  7. How vehicle brakes work · Air brakes versus hydraulic brakes

    Air brakes versus hydraulic brakes — key rule 1

    Hydraulic brakes use brake fluid, which cannot be compressed, so force reaches each wheel immediately; they are used on almost all cars and light trucks.

  8. How vehicle brakes work · Air brakes versus hydraulic brakes

    Air brakes versus hydraulic brakes — key rule 2

    Air brakes use compressed air stored in tanks; they suit large commercial vehicles because they transmit high forces over long distances with simple parts.

  9. How vehicle brakes work · Air brakes versus hydraulic brakes

    Air brakes versus hydraulic brakes — key rule 3

    Every air brake system has a split-second delay between pressing or releasing the pedal and the brakes reacting, while air moves through the system.

  10. How vehicle brakes work · Air brakes versus hydraulic brakes

    Air brakes versus hydraulic brakes — key rule 4

    Special valves keep that delay as short as possible, but it never disappears.

FAQ

Ontario Air Brake (Z) flashcards: questions

Where do these flashcards come from?

Each of the 238 cards is one point from our study notes, which we write from the official The Official Air Brake Handbook (MTO). The front names the rule; the back states it. Nothing on the cards is added beyond those notes.

How should I use the flashcards?

Read the front, answer in your head, then flip. Choose "Got it" only if you knew it; otherwise choose "Review again". At the end, go through the "Review again" cards once more, or pick a single topic from the list to focus on it.

Is my progress saved?

Yes, on this device only. Cards marked "Review again" stay in the "Needs review" list, and every card you rate counts towards your topic map on the exam overview. Nothing is sent to us with your name; you can clear it from the overview page.

Are flashcards enough to pass the Ontario Air Brake (Z) test?

No. Flashcards help you remember the rules, but the test asks multiple-choice questions. Use our practice tests and mock exams as well, and study the official material from Ontario Ministry of Transportation (MTO).
