These are real pages from the book. The table of contents is the full one: 8 parts and 61 topics.
You're at the DMV computer and the question asks what turns the S-cam. Pushrod, slack adjuster, brake chamber: all three sound right.
The manual explains it in one long paragraph: air enters the chamber, pushes the rod, moves the slack adjuster, twists the cam. Read as a sentence, four moving parts blur into one.
In the book, the S-cam brake is one page: the chamber, the pushrod, the slack adjuster and the cam drawn in the order they move, with arrows until the shoes press against the drum.
Same with the governor, the spring brakes, brake lag, the blue and red lines and the 7-step check: each one has its own page.
You see what moves what. You answer the question, and later explain it in the yard, without going back to the manual.
The tests, the air system part by part, the brakes at the wheel, the 7-step check, braking on the road, combination vehicles, General Knowledge and test-day review: 65 pages, all illustrated.
Think of it this way:
You're in the yard, engine running, and the examiner says: "Walk me through your air brake check." Seven steps, and each one has its number.
In the book you flip to the 7-step page and see the gauge drawn with every number marked: cut-out around 125, warning before 55 or 60, spring brakes between 20 and 45, cut-in around 100.
Same with the S-cam brake, brake lag at 55 mph, the blue and red lines and the vehicle inspection order: each one on its own page.
CDL Air Brakes Illustrated is 8 parts and 61 topics, all drawn, and at the end all the air brake numbers on one page, the pairs people mix up and a trace-the-air self-test.
What you see drawn, you don't have to memorize.
Which knowledge tests you take, the CLP and ELDT, the 14-day rule, the air brake restriction and Classes A, B and C at a glance.
The whole air system in one drawing, then each part: compressor, governor, tanks and drains, air dryer, safety valve, foot valve, gauges, low air warning, dual systems and ABS.
How a wheel stops: S-cam brakes, chamber and pushrod, slack adjusters, drums and linings, spring brakes, the yellow diamond knob and when not to park with it.
The air brake check one step per page, always in the same order: cut-out, static and applied leaks, low air warning, spring brakes, build-up rate, cut-in. You say it out loud in the yard without skipping a number.
Brake lag, total stopping distance at 55 mph, emergency stops, snub braking on a downgrade, brake fade, low air on the road and wet brakes.
Blue service line and red supply line, tractor protection valve, the red octagon and why the trolley valve is never for parking.
Inspection order, mirrors, following distance, speed and weight, skids, railroad crossings, cargo, emergencies, fires, alcohol and fatigue.
All the air brake numbers on one page, the pairs people mix up, the questions most asked, a trace-the-air self-test and test day at the DMV.
At the end of the book: All the air brake numbers on one page, the pairs people mix up and a trace-the-air self-test diagram.
Test-style questions on air brakes and General Knowledge, each answer explained with the page where it's drawn, so you know what you really get and what you only guessed.
The most frequent mix-ups (cut-in vs. cut-out, service vs. supply line, spring brakes vs. parking brake) on one-page cards you can review the night before.

Both. It starts from zero with the whole air system in one drawing. If you already drive, it's a quick way to review the numbers before the test or to take off the air brake restriction.
From the state CDL manuals, which follow the AAMVA model manual, and from FMCSA rules (49 CFR Parts 383, 392 and 393). The air brakes section is built on that shared model. Where a detail can differ, like a low air warning set by the manufacturer, the page tells you to check your state manual.
No. It's an independent illustrated study book. Your state's CDL manual is free, it's the official reference, and you should keep using it. This book doesn't replace it: it draws what the manual explains in paragraphs, puts the psi numbers in a box on each page and keeps the same order every time, so you can review it in minutes.
No. ELDT is required by federal rules and only a registered training provider can certify it: this book gives no certificate and doesn't count toward ELDT. Driving can't be learned from a book either. It helps you understand and review what you study there.
No. They're written for this book, in the style of the knowledge tests, and each answer points to the page where it's drawn.
