Comma BF51L Dot 5.1 Synthetic Brake Fluid, 1 Liter

Product Information

DOT 5.1 is glycol-based and has a different wet and dry boiling point when compared to DOT 5 brake fluid. DOT 5.1 is widely used in the automotive industry. DOT 5 is silicone-based and is not commonly used because it's not mixable with water. It seems like everyone should want to be using DOT 5 brake fluid since it has the highest boiling point and absorbs no moisture and won't react with everything else in your vehicle. And while that does make it seem good, there are some issues with it as well. DOT 3 as we mentioned is a glycol-based type of fluid. It has a much lower heat resistance temperature and is old technology. In terms of performance under heavy use and abuse it is quite poor and you should definitely switch on a DOT 5.1 fluid if you want to get something better performing and something that will deliver a lot. And what is good when it comes to these two types of fluids is that they are really interchangeable. You can flush the old DOT 3 and replace it with 5.1.

DOT 5.1 ESP has been designed to complement the very latest ESP, with the low viscosity of the brake fluid allowing for a faster increase and decrease of the pressure needed for varying braking demands. Motul DOT 5.1 brake fluid is an excellent and high-power brake fluid that ensures your hydraulics braking system is super responsive and working optimally. It is one of the best brake fluids you can get in the market. This is ok for drivers who only use their cars at the race circuit. Ordinary drivers who frequently drive their cars on ordinary streets should be more concerned if their fluid meets DOT specification. Brake fluid that do not meet DOT specification can speed up the deterioration of brake components over a extended period time. It can also lead to the malfunctioning of ABS during cold weather. Most people do not know much about brake fluid, and it can be hard to find relevant information to learn more about it. Silicone based fluid is more compressible than glycol based fluid, leading to brakes with a spongy feeling. [14] It can potentially suffer phase separation/water pooling and freezing/boiling in the system over time - the main reason single phase hygroscopic fluids are used. [ citation needed] Characteristics of common braking fluids [15] [14]There are various brake fluid types just like we have seen in the above DOT 3 vs. DOT 4 article. The type of brake fluid you choose will depend on the type of brake system you are using. Most vehicle manufacturers will also recommend for you the brake fluid you should use. This makes it the perfect choice for vehicles that need enhanced braking performance and reduced brake fade. DOT 5.1 also has superior chemical and thermal stability, making it long-lasting and reliable. It is also hygroscopic, which absorbs moisture and prevents corrosion of critical components in your vehicle’s brake system, ensuring your brakes stay safe and reliable over time. How Mechanicaddicts Chooses the Dot 5.1 Brake Fluid This means you should avoid mixing mineral oils and you’ll normally need to buy it from a local bike shop or online bicycle retailer, unlike DOT, which is more readily available given it’s used in the automotive industry. Today, cars are commonly equipped with ABS, and DOT5.1 fluid is used since the viscosity of it helps the ABS work consistently even in cold climates.

High-Performance: With a dry boiling point of 516°F (272°C), Motul's DOT 5.1 Brake Fluid outperforms standard brake fluids, maintaining optimal performance under extreme braking conditions. Convenient: Its compact volume and weight make it easy to transport and store, ensuring you can always have it on hand when needed.A DOT 5 brake fluid does not absorb moisture, and it does not cause any harm to painted surfaces. This brake fluid acts as a weather barrier to the brake system. DOT 5 can replace DOT 3 and DOT 4, but you should not mix it with any of the other brake fluids. Silicon-based brake systems are more difficult to bleed. While your brakes are very unlikely to ever reach these pressures, there is an increased chance of brake fade when the fluid has ingressed water over time and the system is being heated up, for example on a long Alpine descent, compared to when it has been newly bled. High-Performance: Liqui Moly DOT-5.1 brake fluid is designed for high-performance applications, offering superior protection and heat resistance. DOT 5.1 has the highest wet and dry boiling point, but that doesn’t mean it’s the best brake fluid out there. That’s because it has the same chemical properties as other mineral-based brake liquids with lesser wet and dry boiling points.
