HYDRAULIC BRAKING SYSTEM.pdf. INTRODUCTION 2 f INTRODUCTION Early In Automobile development, the brakes played a rather subordinate role because the friction in the drive train was so great that a vehicle was slowed sufficiently even without the brakes being used. Increasing power and speed as well as constantly increasing traffic density led ...
