When disassembling the hydraulic drive of one wheel, you can limit yourself to removing air only from the disassembled cylinder.
If the line was disassembled from the master cylinder to the wheel cylinder, then you can limit yourself to removing air only from this line.
1. With the engine stopped, press the brake pedal several times to restore atmospheric pressure in the vacuum brake booster.
2. Before pumping, restore the fluid level in the tank and maintain the level during pumping, preventing the tank from emptying. Fill with fresh fluid only.
3. Bleeding the brakes should be done by two people. Prepare the liquid, vessel, bleed hose and wrench to unscrew the fitting.
4. Start pumping from the rear right wheel. Loosen the bleed screw and tighten slightly so that it can be easily unscrewed again.
5. Attach a hose to the fitting, lower the other end of the hose into a vessel with brake fluid.
6. Ask an assistant to slowly depress the brake pedal and hold.
7. Unscrew the fitting and after 2 seconds after the flow of liquid flowing out with bubbles weakens, tighten the fitting. Have an assistant release the pedal.
8. Repeat the procedure until there are no more air bubbles in the escaping liquid. Tighten the fitting. Perform these steps in sequence: left rear, right front, left front. Keep an eye on the fluid level in the tank.
9. At the end of pumping, restore the fluid level in the tank.
10. After bleeding the brakes, the pedal should be "tough". Repeat the pumping procedure if necessary.
