Commercial Vehicle Braking Systems
I.D. # C0233 Duration 3 Days

Increased public pressure to improve commercial truck safety and new stopping distance regulations have intensified the need to better understand the factors influencing heavy vehicle braking performance. To assist individuals and their organizations in preparing for these new truck braking standards, this seminar focuses attendees on understanding medium-duty hydraulic brake systems and heavy-duty air brake systems and how both systems' performance can be predicted, maintained and optimized. The function and application of the major brake system components will be explained and attendees will discover how brakes, tires and roadways interact as a system. Federal braking regulations for both hydraulic and air brake vehicles will also be covered. Attendees will receive the text, "Commercial Vehicle Braking Systems: Air Brakes, ABS and Beyond," written by Leonard C. Buckman.

This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 18 Continuing Education Units (CEUs). Upon completion of this seminar, accredited reconstructionists should contact ACTAR, 1-800-809-3818, to request CEUs. As an ACTAR approved course, the fee for CEUs is reduced to $5.00.

Learning Objectives
By attending this seminar, you will be able to:
  • Design safe and efficient braking systems
  • Test and measure braking performance
  • Maintain and troubleshoot braking systems
  • Comply with state and federal regulations on brakes
  • Describe the brake implications of accident investigation

Who Should Attend
This seminar is designed for 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.
