Start with the brake farthest from the master cylinder, usually rear wheel, passenger side. Pull off the rubber cover on the bleeder valve. Attach the aquarium air line to the nipple on the bleeder. Have your assistant pump the brake pedal up and down 3-4 times, then hold the pedal down fairly hard.
All you have to do is fill up the master cylinder reservoir with fresh fluid. Then starting at the wheel farthest from it (typically the right rear), loosen the bleed screw on that brake caliper/cylinder. Go inside and play on your phone for at least an hour. Close the bleed screw and top up the master cylinder.
If what you meant was bleeding the brakes at the calipers to remove air from the system, you should bleed the brakes with the car off. While ‘pump’ was the wrong word to use, the brake booster runs off the engine vacuum (it’s a large diaphragm that multiplies brake force), and this should not be active.
