| FRONT WHEEL BRAKE SCHEMES COMPARED. NOTE: Comparing Hispano with the 'Agreed' Scheme it is seen that the direct brake press. is approx. half that of the 'Agreed' scheme. By making the Hispano leverages the same as the agreed the servo ratio would required for the same results would be about 3 1/2 instead of 7. | ||
