Comma BF51L Dot 5.1 Synthetic Brake Fluid, 1 Liter

Product Information

Then you can connect everything and run your car with the DOT 5 brake fluid. This is a long procedure so you should think twice before you decide on this step. Since you can just get a DOT 5.1 which performs almost the same as the 5. Conclusion 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? It has a completely different chemical structure since it’s made out of silicone and it does not resemble the glycol-based compounds in any way possible. This is why manufacturers gave it a distinctive purple color to make it different so people would not mix these two types of fluid. ISO 4925:2020 - Road vehicles -- Specification of non-petroleum-base brake fluids for hydraulic systems". www.iso.org.

It is recommended to change the DOT 4 brake system every two years to maintain the maximum safety and performance of the brake system. The lifetime of the brake system reduces when water contaminates it. DOT 4 brake fluid absorbs moisture through the brake hoses. The brake fluid heats up as you continue to use the brake system. So just which brake fluids can you mix without causing harm to your brake system? Let's take a look at the chart below. The disadvantage of mineral oil is that it’s unregulated and as a result, not all mineral oils are created equal. DOT 5 brake fluids are silicon fluid, and it is used in most modern cars. It is more expensive compared to others since it has a high bylining point. It has a dry boiling temperature of 356 degrees. Most of the new brake rotors are thin and small, and thus they disperse a lot of heat. This silicon-based brake fluid is ideal for this type of car since it can withstand high temperatures. 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.

But still, you should not mix them together. When it comes to switching from DOT 3 to DOT 4 we would recommend you do perform a complete flush of the system and add completely new fluid. The answer is no – mixing different brake fluids is not recommended. As DOT 5.1 is silicone-based, mixing with standard glycol-ether fluid (DOT 3 or 4) can cause severe damage and compromise the performance of your brakes. Mixing dot 5.1 with other silicone-based fluids (DOT 5) may be safe. However, this should be avoided unless prescribed by the manufacturer. Final Thoughts About Dot 5.1 Brake Fluid Wet Boiling Temp. : Boiling point with fluid that has 3.7% water by volume. After 1-2 years of fluid use.

Now let’s cover the last type of brake fluid which is the DOT 5.1 brake fluid. But why is this fluid called 5.1, is this some kind of an update to the DOT 5 brake fluid? Well, actually no. 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. AN EXPLANATION OF BRAKE AND CLUTCH FLUIDS". Xpowerforums.com. Archived from the original on 2008-11-04 . Retrieved 2015-05-26.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. DOT 5.1 has a higher boiling point when compared to DOT 4, but that doesn’t mean it’s superior to DOT 4. Another interesting thing about the DOT 5 fluid is that it does not absorb water. Glycol-based fluids can be diluted with water but the DOT 5 simply cannot be diluted at all. DOT5.1 : DOT5.1 brake fluid has a dry boiling point of 270 degrees Celsius and a wet boiling point of 180 degrees Celsius.

Brake fluids must not corrode the metals used inside components such as calipers, wheel cylinders, master cylinders and ABS control valves. They must also protect against corrosion as moisture enters the system. Additives (corrosion inhibitors) are added to the base fluid to accomplish this. Silicone is less corrosive to paintwork than glycol-ether based DOT fluids. [14] Now let’s first discuss more on the pros side of things. What are the benefits that you will get if you are running this type of fluid on your car? The chief disadvantage of DOT fluid is that it is hygroscopic, which means it absorbs water, unlike mineral oil. For a faster reaction of the ABS and ESP systems, DOT 4 and DOT 5.1 brake fluids exist with low viscosity meeting the maximum 750 mm 2/s viscosity at −40°C (−40°F) requirement of ISO 4925 class 6. [2] These are often named DOT 4+ or Super DOT 4 and DOT 5.1 ESP.Ideal for drivers looking to upgrade their brakes, Bosch ESI6-32N Brake Fluid is the perfect choice. This brake fluid boasts high compatibility with DOT 3, 4, and 5.1 Standards and offers superior performance and longevity. Its extended service interval lasts up to 100% longer than DOT 3, 50% longer than DOT 4, and 10% longer than DOT 5.1 - making it an excellent choice for extended driving. This fluid is purple in color. Unlike other brake fluids which are clear in color. This way you will never mix them and possibly ruin the braking system on your car.
