Challenges of using Girling brakes with independent suspension on the Bentley, proposing a new brake gear design.

(sheet 3)

When it comes to the question of standardising independent suspension on the Bentley, the use of Girling brakes would present a fresh problem with regard to the means of operating the front brake shoes as the present method of using a transverse pull rod directly operating on the expanding wedge would be inapplicable.

No doubt there is some solution of this problem, but it is rendered somewhat difficult by the brake wedge and steering pivot being on the same centre line, and there is no instance of Girling shoes being used with an independent suspension that we know of.

My recommendation is that we concentrate all our energies on introducing a light brake gear in conjunction with the independent suspension and stiffened up brake of the Bentley, and make this brake gear similar to Bentley III and Wraith.
