Order of execution
1. Fill the expansion tank with fresh brake fluid and keep an eye on (!) for the timely addition of liquid before its level drops. Otherwise, the air will be sucked in again.
2. Sequence of actions: rear right; rear left; front right; ahead on the left.
3. Remove the dust cap from the bleed valve.
4. Put on the transparent hose (like a windshield washer system) on the frayed fitting and lower the free end of the hose into a container partially filled with brake fluid.
5. Have your assistant pump the brake pedal to apply brake pressure.
6. Loosen the bleed valve on the appropriate wheel approximately 11/2 turns and bleed the pressure. In this case, the assistant keeps his foot on the pedal and presses it.
7. Close the valve and pressurize again.
8. Open the valve in the same way.
9. Repeat this process until no more air bubbles are visible in the hose. (If the hydraulic system is very empty, then pump it twice.) In this way, brake fluid is pumped through the valve and, of course, air along with it.
10. If there are no more air bubbles, then have your assistant hold the pedal in the lowest position, while you close the bleed valve. Tighten it carefully, otherwise you will break the thread.
11. Bleed the systems on the remaining wheel brakes in exactly the same way.
Tip: If the brake system does not bleed according to the above method, despite repeated repetitions of this process (air bubbles are still visible), then you must close all bleed valves, start the engine and press the brake pedal several times. Then pump the system again.
Bleeding the brakes on the front caliper. bleed valve (1) opens with SW 7 key. A transparent synthetic hose is put on the valve (2) and the pumped out brake fluid is drained into a prepared container (3).
If the brake lines (2) and brake lines (4) connected with metal brackets (3) with chassis or bodywork, there must be a spring-loaded hose bracket (1). This wrench is suitable for disconnecting the brake pipes (5)
