The Ackermann steering and the Lockheed brakes were fitted to the original design. In fact the reason the axles could not be made removable was because the brake master cylinder / reservoir was inside the rear longitudinal girder, with the wheel brake cylinders at the rear wheels. Flexible brake hoses allowed the axle to rotate and thus lower the mounting onto the jacks. To remove the axle would mean having to remove the flex hose, and this would allow fluid out and air in, and necessitate bleeding the system after reconnecting!
The British Mk.2 Platform had the master cylinder / reservoir fitted directly to the rear axle, so this could be removed without disturbing the braking system.
