EXPERIMENTAL REPORT.
front braking the steering is affected in the same manner as on our 40/50 chassis. Da.{Bernard Day - Chassis Design} has suggested that the effect we get may be caused by a couple with an arm equal to the distance between the wheel and the centre of gravity. In order to prove this we point we have been testing with one back brake only working and we find that the car is steered in a similar manner as with one front, only it does not appear so definite. The roads however are now covered with snow and it is difficult to be sure the wheel does not skid. If the wheel skids we get a different set of conditions.
We believe with standard brakes we shall get fairly even braking. There is no reason why it should be any different to present rear. We have had most unequal braking with the temporary jointed shoes. We have not been able to appreciate any difference with any reasonable difference in tyre pressures on the two front wheels.
