Sequence of execution
1. Prepare the vehicle and the necessary equipment to perform the work ("Preparing the car for maintenance and repair" and "Hydraulic brake drive - bleeding").
2. Remove the tank lid ("Low Brake Fluid Sensor - Checking and Replacing").
To prevent air from entering the hydraulic drive of the brake system when replacing the brake fluid, make sure that its level in the reservoir does not fall below the MIN mark.
3. Using a bulb, remove the working fluid from the reservoir of the main brake cylinder.
4. Pour new fluid into the tank up to the top edge of the tank.
5. Bleed the hydraulic drive system circuits, starting from the rear wheels of the car ("Hydraulic brake drive - bleeding").
6. We bleed each wheel cylinder until the new one starts to come out (lighter) brake fluid from the nipple.
7. After replacing the fluid in both circuits, check the operation of the hydraulic drive and bring the fluid level in the master brake cylinder reservoir to normal.
