Order of execution
1. Remove the cap from the expansion tank and fill it with brake fluid.
Warning! Brake fluid dissolves paint, plastic, and wire insulation, so if you accidentally spill fluid on your vehicle's paintwork or components, wash it with plenty of water.
Attention! When pumping under pressure, do not press the brake pedal
2. Turn away a cover from the union of prorolling of the working brake cylinder and attach to it one end of a transparent hose, and insert other end of a hose into a glass container of sufficient volume, half filled with a brake liquid.
3. Slowly press the brake pedal several times.

5. Repeat steps 3 and 4 until the brake fluid comes out without air bubbles.
6. Tighten the bleed screw. Tightening torque: 7–9 Nm.
