Hongqi, brake system flushing in Yoav

Hongqi, brake system flushing in Yoav.
Brake fluid may lose its properties with time. Thus, it is required to ensure its periodic replacement by flushing the brake system. To do this, first, pump all the brake fluid from the reservoir and flush the reservoir. Then fill it with a new brake fluid, press the brake pedal with an opened wheel bleeder screw until a new fluid flows, which is determined by the fact that it is light and transparent. The manipulation is carried out for each wheel.
