Car pulls to left when braking

Ok,i replaced the front brakes on my 72 Duster.They are still the 9 inch drums,replaced the shoes,and had the drums resurfaced.I was told this was a braking issue and the car rides pretty straight until I brake,then the wheel wants to jerk to the left.Is there a way I need to adjust these?Its been awhile since I messed with front drums.If this helps,I almost need to leave the adjusting star on the left front wheel almost really loosein order to even put the drum on.Any help would be great :read2:
