Braking of Road Vehicles, Second Edition includes updated and new subject matter related to the technological advances of road vehicles such as hybrid and electric vehicles and "self-driving" and autonomous vehicles. New material to this edition includes root causes, guidelines, experimental and measurement techniques, brake NVH identification and data analysis, CAE and dynamic modelling, advances in rotor and stator materials, manufacturing methods, changes to European and US legislation since 2014, recent developments in technology, methods and analysis, and new and updated case studies.

This new edition will continue to be of interest to engineers and technologists in automotive and road transport industries, automotive engineering students and instructors, and professional staff in vehicle-related legislational, legal, military, security and investigative functions.
