DOT 4 brake fluid primarily consists of a mixture of glycol ether and borate esters, which provide its properties. It also contains additives to enhance its performance, such as corrosion inhibitors and anti-foaming agents. Unlike DOT 3 fluid, DOT 4 has a higher boiling point, making it suitable for high-performance braking systems. Additionally, it is hygroscopic, meaning it can absorb moisture from the air, which can affect its performance over time.
