Most auto and bike caliper bleed nipples are the same size. Measure the bike ones and buy tubing to suit. There's no definitive size, it depends to an extent on how flexible the tubing is.
Get a large syringe that fits the tubing and use it to part-empty the master cylinder reservoir. With care, you can also use it as a vacuum device to suck fluid through or - extreme care required - push fluid into the caliper to expel difficult air bubbles.
DOT-4 fluid is a specific standard so all makes will be much the same. I'd buy a litre to be sure you have enough. Overkill most likely but better than having to leave the job halfway to get more.
