Educational Advantages



  • Industry standard glad-hands are used to connect the tractor and trailer together.
  • All air connections are made using D.O.T. approved push-to- connect fittings. This also allows testing for pressure at multiple locations.

  • 9 pneumatic faults
  • Blockages • Leaks
  • Demonstrate real world problems
  • Key connections are equipped with auto-exhausting shutoff valves to facilitate testing and measurement for troubleshooting and problem solving the various inserted system faults.


  • Includes operation manual, pneumatic schematics with and wit- hout faults, instructors guide and student assignments.


  • All air tanks have drain valves and are equipped with safety valves set at 150psi.
  • All actuating rods coming out of the brake chambers are ful- ly protected and enclosed in transparent cylinders to ensure student safety.
