About the Saskatchewan Air Brake test

In Saskatchewan, the air brake test is the A endorsement, administered by SGI. It is a single written exam that applies to any air-brake-equipped vehicle, whatever the licence class, rather than a class of its own.

Air brakes work on the opposite principle from the hydraulic brakes on a car. Air pressure holds the spring-loaded brakes off, so if the system loses air the springs apply the brakes automatically: the design fails safe. Because nearly every heavy commercial vehicle uses air brakes, this qualification is essential in practice, even though it appears as a separate result on your licence.

The knowledge test covers governor cut-out and cut-in pressure (cut-out is typically 120 to 135 psi, with cut-in 20 to 25 psi lower), the low-air warning (it must come on before pressure drops below 60 psi, or 414 kPa), the pressure at which the spring brakes apply (around 20 to 45 psi), slack-adjuster inspection, and the daily leak-down test. Many provinces add a practical demonstration to the written test.
