DOT 4 brake fluid. The primary differences between the two include the following: DOT 3 brake fluid will absorb less water than DOT 4 from the air over time, meaning you'll need to have your fluid changed less frequently. DOT 4 brake fluid has higher dry and wet boiling points, making it safer for higher temperatures.

Is DOT 4 brake fluid purple?

Be aware that as the moisture content of the fluid increases, the boiling point decreases. New glycol-based fluid (DOT 3, DOT 4, DOT 5.1) is a translucent yellow color. In fact, it almost looks clear when you pour it out of the bottle. Fresh DOT 5 brake fluid is a purple color.

Is DOT 4 brake fluid blue?

Is it OK to mix DOT 3 and DOT 4?

Can you mix Dot 3 and Dot 4 Brake Fluid? Yes, Dot 3 and Dot 4 brake fluid can be mixed. It's because both these are glycol-based brake fluids, which means that they are compatible with each other. If your car has Dot 4 from the factory, it's not recommended to fill it with Dot 3, though; but the other way is fine.

Are all DOT 4 brake fluids the same?

Since DOT 4 and 5.1 are both glycol-based brake fluids they are compatible with each other, which means they can be readily mixed without harming your brake system. It is important never to mistake DOT 5.1 (glycol-based) with DOT 5 which is silicone-based and should never be mixed with any other DOT fluid.

Does brake fluid look like water?

What Does Brake Fluid Look Like? Brake fluid, unlike engine oil or antifreeze, is colorless. It is much lighter than those fluids, too, with a consistency like vegetable oil. If you see a puddle under your car, look closely to see what type of fluid it might be.

Is Dark brake fluid bad?

Very dark colors indicate that your fluid has collected a significant amount of contamination, and might have absorbed moisture, as well. This reduces the system's ability to build pressure, which compromises your braking performance. You may have noticed that your brake pedal feels softer, or spongy.
