Program Overview:

This course provides the students with the knowledge of how an Air Brake system operates and being able to identify its major components. The student is prepared for the official Ministry of Transportation (MTO) Air Brake endorsement test. Students learn the legislated parameters for the operation on the Air Brake system under the Highway Traffic Act (HTA), as well as how to test and verify that a commercial vehicle’s Air Brake system is operating within these parameters.

In addition, the students learn how to incorporate the air brake tests into their pre-trip inspections and get hands-on practice with the system tests before being tested. The written and practical tests are conducted at our facility. Our instructors have signing authority to sign-off for students who have successfully completed the written and practical tests. The participant would then go to a DriveTest center to have the “Z” endorsement put on their license.
