Stepped Bore Master Cylinder-A Way of Improving Dual Brake Systems

It is now several years since most passenger vehicles were provided with a dual circuit braking system. The increased safety which has been obtained by this, has the disadvantage of extra pedal movement and increased pedal force which is then required when one circuit has broken down. Besides the deterioration in braking performance it can give the driver a shock. By replacing the tandem cylinder of conventional type hitherto used with a new type, these disadvantages have practically been eliminated.
