After installing the brake pads, press the brake pedal hard several times while the vehicle is stationary so that the brake pads take the position corresponding to their working condition. To pump out the brake fluid from the expansion tank, use a pumping container that only comes into contact with the brake fluid. Brake fluid is a toxic substance, so it must never be pumped out by mouth through a hose! Check the smoothness of the brake caliper by moving it laterally.
