Which brake fluid is silicone based?

Silicone-based brake fluid is primarily known as DOT 5. This type of brake fluid is distinct because it has a higher resistance to moisture absorption and does not damage paintwork or other components in the event of a spill. It also offers a significant advantage in terms of maintaining its performance across a wider temperature range compared to glycol-based fluids like DOT 3 and DOT 4. While DOT 3 and DOT 4 are popular and commonly used in various vehicles, they are based on glycol and not silicone. Choosing the appropriate brake fluid is essential for optimal braking performance and system compatibility, with DOT 5 serving specific applications, such as in vehicles subjected to extreme conditions or where moisture sensitivity is a concern.
