Bleeding is performed after opening the hydraulic brake circuits, and also whenever the brake pedal becomes "soft" and it is necessary to press it several times for the brakes to start working.
Introductory remarks
Do not unscrew the rear brake bleeders when the hydraulic accumulator is under pressure or when the brake pedal is pressed. The hydraulic brake supplies the rear brake circuit at a pressure of 18 MPa.
Before performing any actions that may cause brake fluid to leak, be sure to relieve the pressure in the accumulator by pressing the brake pedal hard about 20 times.
When servicing, adjusting or repairing the brakes, do not turn on the ignition unless required by the service manual.
You should use the brake fluid recommended by the vehicle manufacturer and pour it from the original, freshly opened containers.
When bleeding the brakes, maintain the required level of brake fluid in the reservoir at all times.
Bleeding the front brake circuit
1. Place a transparent tube made of artificial material on the front brake deaerator. Place the other end of the tube in a transparent container filled with brake fluid.
2. Press the brake pedal. If it does not offer resistance, then press it until it begins to offer significant resistance.
3. With the brake pedal depressed, loosen the deaerator. Keep the pedal depressed until air bubbles are visible.
4. Screw in the deaerator and release the brake pedal.
5. Repeat the last two operations until brake fluid starts flowing out of the tube without air bubbles.
6. Remove air from the second front brake circuit in the same way.
Bleeding the rear brake circuit
1. Place a transparent tube made of artificial material on the rear brake deaerator. Place the other end of the tube in a transparent container filled with brake fluid.
2. Press the brake pedal.
3. Loosen the deaerator.
4. Turn on the ignition. This will activate the hydraulic pump and brake fluid will start to flow out of the tube. You should wait until the emerging fluid does not contain air bubbles.
5. Release the brake pedal and screw in the deaerator.
6. Turn off the ignition and wait until the hydraulic pump stops.
7. Repeat these steps to remove air from the second rear brake circuit.
