This is one of the best brake fluids for classic race cars on the market today and for many reasons. For starters, it boasts high velocity coupled with even viscosity to ensure fast and precise response in the brake system.

What’s more? The brake fluid features a low freezing point of -40 degrees Celsius, thereby making it ideal for snow rally. However, it can also be used in all types of vehicles, including streetcars.

But here is the best part; the product is designed to maintain a high dry boiling point. Consequently, this makes it best for Formula 1, Dakar, and WRC rally cars.

Pros

  • Offers reliable braking force
  • Delivers superior performance
  • Consistent and stable brake pedal feel
  • High dry boiling point

Cons

  • A little expensive but worth the money

Buying Guide – What to Look Out for In the Top Brake Fluid for Race Cars

With so many products available, how do you tell which is the right racing brake fluid for your classic race car? Besides, there isn’t one product that will be right for every vehicle. 

But don’t worry because knowing what features to look out for can help you get around a worthy purchase. That said, here are some of the important things to consider when choosing a braking fluid for racing.

Type of Brake Fluid

Generally, there are 4 main types of racing brake fluids, including DOT 3, DOT 4, DOT 5, and DOT 5.1. DOT 3 brake fluid is best for vehicles that do normal driving because of its lower wet and dry boiling points. 

With DOT 4 fluid, it is considered to be ideal for racing cars because of its ability to withstand higher temperatures. The best part? It can be safely mixed with DOT 3 and DOT 5.1 products.

DOT 5, on the other hand, also has an extremely high wet and dry boiling point just like DOT 4. As such, it’s best suited for high-performance vehicles like race cars. However, the product cannot be mixed with other types of brake fluids.

Last but not least, we’ve got the DOT 5.1 brake fluid that is best suited for racing cars with the ABS braking system. It also boasts a high dry and wet boiling point and is designed to absorb moisture. More so, it can be mixed with DOT 3 and 4 brake fluids.

Viscosity

Another factor to consider is if the racing brake fluid can maintain its viscosity despite the operating temperatures.

The product’s ability to maintain its viscosity ensures proper stability and traction control. However, it’s advisable to use brake fluids that have viscosity levels as recommended by your vehicle’s manufacturer.

Overall, DOT 5.1 brake fluids are known to boast the lowest viscosity over a wide range of temperatures.

Water Protection

The braking system is designed to be porous in nature. So, when water penetrates into the system, it could dilute the brake fluid. Consequently, it may compromise the performance of the product.

What’s more? The water could turn into steam when you brake at high temperatures, thereby making the brakes less responsive.

So, you must choose a product with excellent moisture protection, especially if you live in areas with wet driving conditions.

DOT Level

DOT levels are simply the estimates of a brake fluid’s boiling point. Generally, a higher boiling point means that the product can withstand increased temperatures when braking.

Therefore, if you drive a high-performance vehicle like those used for racing, the best product should have higher DOT levels.

Typically, some of the best brake fluids for classic race cars use premium DOT 4 or OT 5 products. However, streetcars require only DOT 3 fluid.

Frequently Asked Questions

Below are answers to some of the commonly asked questions about the top-rated racing brake fluids on the market.

Q: Which is better DOT 3 or 4?

A: For racing cars, DOT 4 is the best because of its lower viscosity along with high wet and dry boiling points. DOT 3 fluid, on the other hand, is best for streetcars.

Q: What color is DOT 4 brake fluid?

A: It’s almost mineral clear but with a little composition of yellow.

Q: How often does brake fluid need to be changed?

Q: Is brake fluid flush really necessary?

A: Yes. Experts consider flushing or changing the fluid as preventive maintenance of your vehicle. 

Q: Does braking fluid go bad?

A: Yes, it does. This usually happens when it absorbs moisture, thereby reducing its performance.
