Pads can be very expensive and probably won't do much if there is not good tension. Amazon has one v brake kit for 25 bucks and one for 40 bucks, both are all inclusive. I got the 40 buck one recently but it did't arrive yet. Should be adequate but if not then one shamino btr4000 brake for front or back is 15 bucks more, so still much cheaper than if you got all the parts separately.
