- proceed in the same order as when bleeding, but use a hose with a glass tube at the end, which is lowered into a vessel with brake fluid;
- while pressing the brake pedal, pump out the old brake fluid until new fluid appears in the tube (lighter) fluid, then perform two full strokes with the brake pedal and, while holding it down, tighten the fitting. When pumping, monitor the fluid level in the tank and top up the fluid in a timely manner to the maximum level;
- repeat the same operation on each working cylinder in the same order as when pumping;
- fill the tank to the maximum level and check the operation of the brakes while driving.
