Heavy duty
drive axle with cutaway differential and 2 different types
of S-Cam brakes allow instructor to train on foundation
brake troubleshooting, repair and rebuild on separate
braking systems. This eliminates the need for multiple axles
when training mechanics fleets with multiple types of
brakes. Differential operation and parts identification can
also be shown. This includes a view of internal gearing
operation not commonly available to the student.
