You will need: a 9 mm wrench, brake fluid, a rubber or transparent hose, and a transparent container.
USEFUL TIP: We recommend replacing the brake fluid with an assistant, after first placing the car on a ramp or inspection ditch (no need to remove the wheels).
The order of replacing the fluid in the brake mechanisms:
- rear right;
- front left;
- rear left;
- front right.
WARNING: Apply the parking brake and place wheel chocks under the wheels.
Do not reuse drained fluid: it is contaminated, saturated with air and moisture. Always add only new fluid of the same brand that was previously poured into the system.
Brake fluid is hygroscopic (absorbs moisture from the surrounding air), so it cannot be stored in an open container.
Protect the environment! Do not dispose of used brake fluid into the soil or sewer system.
1. Turn away…
2….and remove the cap of the master brake cylinder reservoir.
3. Using a medical syringe or rubber bulb, pump out the old brake fluid from the reservoir.
4. Add new brake fluid to the lower edge of the filler neck.
5. Clean the rear wheel air release valve from dirt.
6. Remove the valve protective cap.
7. Attach the hose to the rear brake master cylinder bleeder valve and place the other end of the hose in a clean, clear container.
8. The assistant should sharply press the brake pedal four to five times (with an interval of 1–2 seconds between presses), and then hold the pedal pressed.
9. Loosen the air bleed valve by 1/2–3/4 of a turn. Old (dirty) brake fluid will start to flow out of the hose. The brake pedal should smoothly go all the way down at this time. As soon as the fluid stops flowing out, close the air bleed valve.
NOTE: Always monitor the brake fluid level in the reservoir, not allowing it to drop below the "MIN" level on the reservoir wall. If necessary, add new brake fluid to prevent air from entering the hydraulic drive. This ensures that the old fluid is gradually replaced by the new one without draining the hydraulic system.
10. Clean the front wheel air release valve from dirt.
11. Remove the valve protective cap.
12. Attach the hose to the left front wheel brake master cylinder bleeder valve and place the other end of the hose in a clean, clear container.
13. The assistant should sharply press the brake pedal four to five times (with an interval of 1–2 seconds between presses), and then hold the pedal pressed.
14. Loosen the air release valve 1/2–3/4 of a turn. Old (dirty) brake fluid will start to flow out of the hose.
The brake pedal should smoothly go all the way down at this time. As soon as the fluid stops flowing out, close the air release valve.
15. Replace the brake fluid in the second circuit (first in the working cylinder of the rear brake mechanism, then in the front wheel).
16. Repeat steps 9 and 14 until the fluid in the drive is completely replaced (clean fluid without air bubbles should flow out of the hose).
17. After replacing the brake fluid, be sure to put the protective caps on the air release valves to prevent corrosion.
