Increased public pressure to improve truck safety and new government braking regulations for commercial vehicles have intensified the need to better understand the factors influencing heavy vehicle braking performance. In this e-Seminar, Instructor Leonard Buckman focuses on understanding medium-duty hydraulic brake systems and heavy-duty air brake systems and how both systems' performance can be predicted, maintained and optimized. He explains the function and application of the major brake system components and helps you to discover how brakes, tires and roadways interact as a system. Federal braking regulations for both hydraulic and air brake vehicles are also covered.

Based on the popular classroom seminar, this more than 18 hour course offers an overview, seventeen modules and course exercises accompanied by this handbook. The text, Commercial Vehicle Braking Systems: Air Brakes, ABS and Beyond, written by the instructor is included as a reference.

Is this e-Seminar for You?
This e-Seminar is geared toward engineers and technicians who are involved in the design, development and testing of heavy vehicle brakes. Fleet personnel involved with safety and brake system specification and maintenance, driver-trainers, and truck accident investigators will also find this course of value.

This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 18 Continuing Education Units (CEUs). Upon completion of this e-seminar, accredited reconstructionists should contact ACTAR, 800-809-3818, to request CEUs. As an ACTAR approved course, the fee for CEUs is reduced to $5.00.

This course satisfies a requirement in the Vehicle Dynamics Certificate Program.
