Air brakes work by pressing the brake pedal, which allows compressed air to enter the front brake cylinder and rear brake spring cylinder through a one-way valve. This action pushes the brake arm, causing the brake cam to rotate and expand the brake shoes to tightly contact the brake drum, achieving the braking effect. Below are specific details about air brakes: 1. Components: The air brake system consists of a brake control mechanism, dual-circuit brake mechanism, central disc brake mechanism, brake, and air compressor, among others. 2. Air brake technique: Vehicles with air brakes require at least 3 bars of pressure to move, ensuring effective braking performance.

What to Do If Coolants Are Mixed?

If coolants are mixed, it is necessary to completely drain the coolant from the radiator, then rinse it thoroughly with pure water, and refill it with new coolant. Different colors and brands of antifreeze may have different chemical compositions, and mixing them can easily cause adverse reactions, leading to reduced antifreeze effectiveness. It may even generate flocculent substances that can clog the cooling system. In severe cases, it can cause abnormal corrosion to the engine water channels and cooling pipes. Antifreeze prevents the coolant from freezing and expanding during cold seasons, which could crack the radiator or damage the engine cylinder block. Coolant should be used year-round. As part of regular vehicle maintenance, the engine antifreeze should be replaced annually.
