DESCRIBE THE PRINCIPLES OF BRAKING AND BRAKING SYSTEMS
INTRODUCTION
Braking action on wheeled vehicles is the use of a controlled force
to hold, stop, or reduce the speed of a vehicle. Many factors must
be considered when designing the braking system for an automotive
item. The vehicle weight, size of tires, and type of suspension are
but a few that influence the design of a system.
