My p/u will lock the brakes on hard braking but I do have the late cast iron model B style drums on the front . As the front end is flexible there is a servo element when braking as the backing plate rotates forward very slightly under braking load . The actuator being on the top is "assisted" by this. The reverse is true at the rear brakes .I have seen front radius rods bent when on a car with hydraulics and "B" drums .Could be Ford engineers realised the servo effect so set the rear bias so achieving even braking on all wheels,just my nutty theory .

John in sadly in total lockdown cant go out in my A Suffolk County Egland .
