In all cases the brakesare internal expanding, the external contracting brakebeing quite unknown in Europe. Large use is made ofribbed cast aluminum drums with steel liners and alumi-num shoes, this combination of metals being adopted in. Fig. 18—Hispano-Suiza brake connections.

The Perrot System Advantages claimed for the Perrot system (Delage, Dar-racq, Hispano-Suiza, etc.) are that the whole of the brakeoperating mechanism being placed at the highest pointthere is the maximum protection against mud and is quite an easy matter, by the use of a leather gaiter,to completely protect the moving parts of the telescopiccamshaft. The braking is not seriously affected with thisdesign in case the front axle is bent in an accident,whereas with the brake camshaft mounted in the axle anyaccident to this latter makes the brakes inoperative, andthe breakage of the main leaf of the front spring rendersthe brakes on the front wheels useless. As a remedyagainst this Bellanger uses double springs at the front14), held to the axle
