1968 newport 383/727

Low optioned car.. no power brakes.... works ok but pulls to the left a bit sometimes and that is unpredictable so a bit scary...usually from high speed. Gonna check the brake adjustment and also the bearings.... My dad's '68 had power brakes and as I recall they were very "touchy".. my question is: are power brakes a simple matter of adding a booster? Master Cylinder? is this easy?
