| (3) re. STEERING. Consistent brakes and effective equalis- ers should keep both front brakes equal except in case of oil or water upon the braking surfaces. (In passing several materials are available and I hope being tested.) This there seems little chance of providing for except that every care should be taken to avoid oil getting in from an overfilled hub. Given centre point steering one can only see that the unequal braking affects the steering because of the inclination of the pivots in front elevation. The torque causing pressure on the pivot bearing I think acts at a different leverage on the top compared with the bottom bearing. The force being equal would cause a torque that would affect the steering. Will DA.{Bernard Day - Chassis Design} kindly confirm this point. I can suggest no remedy. We should not be worse than others, and the only true solution would be a vertical pivot within the hub. Do any of the new designs that DA.{Bernard Day - Chassis Design} and I found before I left promise to be worth changing to on EAC.2 ? R.{Sir Henry Royce} | ||
