Most people don’t know the difference between Dot 3 brake fluid and Dot 4 brake fluid. They are both hydraulic fluids that transfer force in a hydraulic system, but they have different chemical compositions. Dot 3 brake fluid is made of glycol ethers, while Dot 4 brake fluid is made of synthetic hydrocarbons. This means that Dot 3 brake fluid is more likely to absorb moisture, while Dot 4 brake fluid is more resistant to high temperatures.
What is Dot 3 Fluid Brake ?
Dot 3 fluid brake is a type of hydraulic brake fluid. It is made of glycol and has a high boiling point. Dot 3 fluid brake is used in vehicles with disc brakes or drum brakes. Dot 3 fluid brake helps to transfer the force from the pedal to the brakes. It also prevents the brakes from overheating.
What is Dot 4 Fluid Brake?
Dot 4 fluid brake is a high-performance brake fluid that provides excellent performance in both high and low temperature conditions. It is formulated to resist vapor lock and fade, and has a higher boiling point than other brake fluids. Dot 4 fluid brake also provides superior corrosion protection and is compatible with all types of brake systems.
Main differences between Dot 3 Fluid Brake and Dot 4 Fluid Brake
Dot 3 and Dot 4 brake fluids are both glycol-based fluids, however they are not compatible with each other. Dot 3 fluid is typically used in light duty vehicles such as passenger cars, while Dot 4 fluid is used in heavy duty vehicles such as trucks and buses.
The main difference between these two types of brake fluid is their boiling point. Dot 3 fluid has a boiling point of 205 degrees Celsius, while Dot 4 fluid has a boiling point of 230 degrees Celsius. This means that Dot 4 fluid can withstand higher temperatures before it starts to break down.
Another difference between these two types of brake fluid is the way they absorb moisture. Dot 3 brake fluid is more hygroscopic, meaning it absorbs moisture from the air more easily than Dot 4 brake fluid.

What are the potential downsides of
There are many potential downsides to using Dot 3 fluid brake rather than Dot 4 fluid brake. One downside is that Dot 3 fluid brake can cause braking system failure. Another downside is that Dot 3 fluid brake can reduce the life of your brakes. Finally, Dot 3 fluid brake can also cause your brakes to feel spongy or unresponsive.
In conclusion,it is important to know the difference between Dot 3 and Dot 4 brake fluid. Dot 3 fluid is typically used in passenger vehicles, while Dot 4 fluid is typically used in performance or racing vehicles. Dot 3 fluid has a lower boiling point than Dot 4 fluid, so it is less likely to cause brake fade. Dot 4 fluid has a higher boiling point than Dot 3 fluid, so it is more likely to cause brake fade.
