This video demonstrates the Engine Brake's driver controls and operation.

The final segment covering the use of an Engine Brake on slick roads was edited out. The practice of using an Engine Brake on slick roads causes tractor jackknifing and is extremely dangerous. Additionally, contrary to what this video states NEVER descend a grade in a gear or at a speed higher than you normally would without an Engine Brake. These are promotional claims that are not endorsed by us or any other truck safety professionals.
