The semi Girling cars have a more elaborate cross shaft which, properly adjusted, gives front/rear balance.
For the same length levers the Girling sytem has much greater leverage so with the later cross shaft I would expect the rear brakes to predominate, maybe even lock.
With the earlier 1932-36 cross shaft the importance of firm location of front axle was recently laboured but I cannot recall just where. With reduced leverage and lesser lever movement the usual recommendation for distict front lead may result in rears doing little.
