One topic per page, the drawing that shows you how it works and the boxes with what you need to know:

These are real pages from the book. The table of contents is the full one: 9 parts and 57 topics.
You've read the service brake section three times. You close the handbook...
...and you can't remember what comes after the pedal valve. The order never stuck.
Here the service brake path is a drawn sequence, six steps in a row: from the dry tanks, through the pedal valve, to the chamber, the pushrod and the drum at the wheel.
And on the pages next to it, every part of the system has its own: the governor, the spring brakes, the gladhands, the S-cam and the eight operation checks.
First you understand why it works that way. Then the order stays with you on its own.
The Z endorsement, air supply, service brakes, spring brakes, trailer brakes, foundation brakes, brakes while driving, the operation check and brake adjustment: 61 pages, all drawn
Imagine this:
Instead of rereading half a page about the governor without being able to picture it...
...you open the page and find one gauge with cut-out and cut-in marked on it, 138 to 173 kPa (20 to 25 psi) apart, cut-in always lower.
And the dry tanks, spring brakes, gladhands, the S-cam and the eight operation checks turn into drawings and tables you can read at a glance.
You stop cramming and start understanding.
That's exactly what The Air Brake Sketchbook: Z Endorsement does. It's not “just another manual.” It's 9 parts and 57 drawn topics, with the eight operation checks in the handbook's order, one page per test.
Because what your brain sees organized, it remembers.
What the air brake system is, the steps from your licence to the Z endorsement, the knowledge and practical tests, air vs hydraulic brakes and other provinces.
So the gauge numbers stop swapping in your head: the governor's cut-out and cut-in, the compressor, the normal pressure range, the air dryer, the wet tank, check valves, the dry tanks, draining, the safety valve and the low air warning.
The service brake path from pedal to wheel, the brake pedal valve, the two circuits, inside a service chamber, and pushrod stroke and air pressure.
The spring brake chamber, how air holds the spring back, the yellow parking brake knob, when spring brakes apply on their own and why caged springs are hands off.
Red and blue gladhands, supply and service lines, cross-connected lines, the red trailer supply knob, the tractor protection valve, the trailer hand valve and trailer spring brakes.
The S-cam force path, the parts of a drum brake, the slack adjuster, wedge brakes and air disc brakes.
Brake lag, speed, weight and stopping distance, heat and brake fade, and what ABS does and doesn't do.
So you can run the check without skipping a step: securing the vehicle first, then the eight tests in official order, one page each, from the low air warning to the drain valves.
Measuring the applied pushrod stroke, the wheel-by-wheel inspection, what counts as a defect, chamber size and adjustment limit, automatic slack adjusters and what to bring to the practical test.
At the end of the book: The eight operation checks in the handbook's order, one page per test.
The eight air brake operation tests in the handbook's order, with what to watch and the pass/fail line for each from the handbook numbers, on a printable checklist you can review before the practical.
Printable cards with the term on the front and a one-line definition plus a tiny sketch on the back, so you can review the vocabulary in short breaks.

The system finally drawn out: why spring brakes apply on their own, what brake lag is and how the S-cam turns air into stopping force.

For anyone in Ontario adding the Z endorsement: starting a DZ, AZ or bus licence, taking an air brake course, retaking the test, or already driving with air brakes. No mechanical background needed: page one starts with what the system is, and each page builds on the one before. It follows Ontario's Official Air Brake Handbook; in another province the air system works the same way, but check your province's rules for the endorsement and the test. Check the index above for every topic.
The Official Air Brake Handbook of the Ontario Ministry of Transportation (MTO) on ontario.ca, updated February 24, 2026, and the ontario.ca page "Get a truck driver's licence". For official purposes, the Highway Traffic Act of Ontario and its regulations apply.
No. It's an independent, drawn study companion to the Official Air Brake Handbook. It does not give you a certificate, and it does not count as an air brake course or replace any DriveTest test. To get the Z endorsement you still take the official knowledge and practical tests (or a recognized course). It is not affiliated with or endorsed by the MTO, DriveTest or ServiceOntario.
No. It helps you study the handbook with drawings. It doesn't replace the official handbook, an air brake course or hands-on training on a real vehicle.
No. Any practice questions in our materials are written by us to help you train. They are not official questions from any test.
Yes. The book and the two bonus books are PDFs you can read on your phone or tablet, or print at home.

You don't have to reread the same page hoping it sticks this time.
You don't have to memorize air pressures you can't picture.
And you definitely don't have to walk into the test not knowing where to start.
One last thing before you decide: you already have the handbook. This gives you the same content drawn, one topic per page, with the eight checks in official order and two bonus books. PDF by email, and 30 days to tell us if it didn't work.
