Comma BF51L Dot 5.1 Synthetic Brake Fluid, 1 Liter

Product Information

But when it comes to the performance 5 has a ton of positives in comparison to the DOT 3. This type of fluid is basically a ton better than the 3 and will work on any conditions out there and deliver the performance that you need. But what about changing from DOT 3 to DOT 5 brake fluid? Let’s elaborate more on that next. Changing From DOT 3 To DOT 5 Brake Fluid Having to choose a brake fluid is not as easy as you probably think because there are more than a few of them and this could be a big challenge for you as a car owner because choosing the right one will be a big headache in some cases. 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. Brake fluids are responsible for transmitting pressure from the brake lever to the brake pads. These fluids need to be non-compressible for them to transfer the force effectively. The best brake fluid should be able to lubricate the calipers, offer resistance to corrosion, and have a high boiling point. Brake fluid comes in four types. There are DOT 3, DOT 4, DOT 5.1, and DOT 5 brake fluids. Brake fluids are subjected to an average amount of heat since brakes convert kinetic energy to heat.

The different numbers in brake fluid represents the different ways that these brake fluids handle temperatures. The rating refers to the fluid’s boiling points when they are either wet or dry. Brake fluid with a higher boiling point will typically last longer than one with a lower boiling point.Now let’s discuss the DOT 5 brake fluid, how the DOT 5 is different in comparison to other types of brake fluids that are out there?

The advantage of the silicon based DOT5 fluid is that it absorbs no moisture whatsoever, unlike the glycol-based fluids. Because it is also chemically inert it won't react with other chemicals in your braking system, nor will it even react to your car's paint which the glycol-based fluids will. For that reason,DOT5 fluid is also preferred for vintage and antique cars that don't get driven around a lot. It can be left to sit in the system arguably for the life of the car without causing any problems. Wet Boiling Temp. : Boiling point with fluid that has 3.7% water by volume. After 1-2 years of fluid use. DOT5 : DOT5 brake fluid has a dry boiling point of 260 degrees Celsius and a wet boiling point of 180 degrees Celsius. It also offers strong corrosion protection and resists absorbing moisture, so your brakes will stay in top-notch condition for longer. DOT-5.1 brake fluid from Liqui Moly also has extremely low compressibility, making it the perfect solution for racing and high-performance applications where precision is paramount.Most brake fluids used today are glycol-ether based, but mineral oil ( Citroën/ Rolls-Royce liquide hydraulique minéral ( LHM)) and silicone-based (DOT 5) fluids are also available. [1] Standards [ edit ] Mixing DOT 3 and DOT 4 will give you an unpredictable boiling performance, which should not cause any harm. These brake fluids are compatible with one another, and thus, there is no problem in mixing them. The difference between the two is minimal. However, professionally, I would advise you to use one or the other instead of mixing. When Should I Use DOT 4 Brake Fluid? Finish Line High-Performance DOT 5.1 Brake Fluid is the industry leader in bicycle hydraulic disc brake fluid. It has been specifically engineered to prevent foaming and overheating and will (out)-perform substandard brake fluids, allowing for superior lever response and pad retraction. With maximum fluid life and braking performance even at low temperatures, this brake fluid is compatible with all brake systems currently sold. Still, though, it has the same temperature characteristics as the DOT 5. This means that it has a dry boiling point of about 500 degrees Fahrenheit and a wet boiling point of 356 degrees Fahrenheit. Which is a good improvement over the old designs such as the DOT 3 and 4. But what about the DOT 5 brake fluid, what are its pros and cons? Well, that’s what we are going to cover next.
