AIR BRAKE Interactive E-Board Tractor Trailer

(Advanced Learning and Diagnostics)


About AIR BRAKE Interactive E-Board Tractor-Trailer Edition

AIR BRAKE Interactive E-Board Tractor-Trailer Edition is an air brake training and teaching resource designed for instructors teaching advanced Tractor and Trailer air brake system operation and diagnostics.  E-Board Tractor-Trailer will provide your air brake service technicians with the advanced air brake system design and operational detail they require to effectively maintain, diagnose and repair both modern tractor and trailer air brake systems. 

The E-Board Tractor-Trailer Edition Package

The E-Board Tractor-Trailer teaching resource package consists of a 100-page Instructor’s Reference and Presentation Guide, complete with student exercise drawings, supported by 44 highly detailed component and system animations.

What Your Students or Service Technicians Will Learn?

Using detailed and clearly understandable system illustrations, your students will first learn to identify the various sub-system circuits associated with both tractor and trailer air brake systems, and identify the individual components associated with each system. They will then see and learn how air is pressurized, stored and delivered to the various sub-systems and how the components, valves and wheel brakes function as the service and spring brakes are applied and released. They will also see exactly how the trailer supply/emergency and trailer service brake systems function. Finally, they will see a number of actually system failure scenarios.

AIR BRAKE Interactive E-Board Tractor-Trailer IS NOT a re-assembly of age-old air brake training material that has been around for decades. E-Board Tractor-Trailer employs ALL NEW and ORIGINAL MATERIAL.  Its content, structure, system diagrams, technical animations and illustrations have been carefully designed and created to reflect current air brake technology. E-Board Tractor-Trailer is the most comprehensive and effective advanced learning and diagnostics air brake teaching resource available today.
