How to Choose the Best Brake Fluid for a Track-Ready Nissan GT-R?

If you’re a car enthusiast, you know that the brake system in your Nissan GT-R is crucial, especially if you’re into track days or racing. As racing fanatics, we understand the importance of using the right brake fluid for the job. But how do you choose the best one? The answer isn’t always straightforward. It depends on various factors, including the type of track, your driving style, and the condition of your car’s brake system. To help you make an informed decision, we’ve put together this comprehensive guide.

Understanding the Basics of Brake Fluids

Before you can choose the best brake fluid for your track-ready Nissan GT-R, it’s essential to understand what brake fluid does and why it’s so important. The brake fluid in your car is responsible for transferring the force you apply to the brake pedal to the brake calipers. In turn, these calipers push the brake pads against the rotors, causing your car to slow down or stop.

The brake fluid in your car operates under extreme conditions. It must remain stable under high temperatures, resist corrosion, and maintain a constant viscosity. That’s where the different types of brake fluid come into play.

The Different Types of Brake Fluid

There are several types of brake fluid available on the market, but they all fall into two categories: glycol-based and silicone-based. The main difference lies in their boiling points and how they behave under high temperatures, an important consideration when choosing brake fluid for a track or racing environment.

Glycol-based fluids are the most common and are generally recommended for cars with ABS systems, like your Nissan GT-R. They have a higher boiling point, which means they can handle the heat generated during hard braking. However, they are hygroscopic, meaning they absorb water over time, which can lower their boiling point. Therefore, it is crucial to replace them regularly.

Silicone-based fluids, on the other hand, are not hygroscopic, so they maintain their boiling points for longer. But they have a lower initial boiling point, making them less suitable for high-performance or track use.

Analyzing Your Driving Style and Track Conditions

Your driving style and the conditions of the track you’ll be racing on will also impact your choice of brake fluid. If you’re an aggressive driver who likes to brake late and hard, you’ll generate more heat in your brakes, requiring a fluid with a higher boiling point.

The type of track also plays a role. If it’s a high-speed track with long straights and few corners, the brakes will have more time to cool between hard braking events, which may not require as high a boiling point. However, a tight, twisty track with numerous heavy braking zones will demand a fluid that can handle the heat.

Considering Your Brake System Condition

The age and condition of your car’s brake system should also be considered when choosing brake fluid. Older brake systems may have more wear and tear on the seals and hoses, necessitating a fluid that’s more resistant to corrosion.

Moreover, if you’ve upgraded your Nissan GT-R’s brake system with performance parts like larger rotors or calipers, or if you use racing brake pads, these can generate more heat, which would require a fluid with a higher boiling point.

Looking for High-Quality Brands

Finally, while there are many brands of brake fluid to choose from, not all are created equal. Look for reputable brands that are known for their high-quality products and have positive reviews from users. Some of the top brands, favored by Nissan GT-R owners and track day enthusiasts alike, include Brembo, Castrol, and Motul.

Brake fluid might not be the most glamorous aspect of track day preparation, but it’s undoubtedly one of the most critical. By considering your brake system condition, driving style, and track conditions, and by choosing a high-quality product, you can ensure your Nissan GT-R will always stop on a dime, no matter how hard you push it on the track.

Remember, the safety of your car, and more importantly, yourself, depends on the proper functioning of your brake system. So, don’t overlook this essential component of your car’s usability and safety.

The Role of High-Quality Brake Pads

A discussion about brake fluid would be incomplete without mentioning the role of brake pads. The type of brake pads you use has a direct impact on the performance and life span of your brake fluid. High-performance brake pads are specifically designed to handle the intense heat generated during aggressive braking. Therefore, pairing a high-quality brake fluid with the right brake pads can significantly enhance your Nissan GT-R’s track performance.

When selecting brake pads, consider factors such as friction level, heat range, and material composition. The ideal brake pad should provide consistent performance and excellent heat dissipation under a range of conditions. It’s also essential to ensure the brake pad you choose is compatible with your chosen brake fluid. For instance, certain pads may work better with glycol-based fluids, while others are better suited for silicone-based fluids.

Reputable brands that offer high-quality brake pads include Brembo, which is highly favored by Nissan GT-R owners, and Motul, which has received numerous positive reviews from users. Always remember to consult your mechanic or a trusted track expert before making your choice to ensure you’re making the most informed decision possible.


Choosing the right brake fluid for your track-ready Nissan GT-R is not a decision to be taken lightly. With so many variables to consider, including the type of track, your driving style, and even the condition of your brake system, it’s clear that there’s no one-size-fits-all solution.

Ultimately, the best brake fluid is one that can handle the heat generated by your driving style and track conditions, resist corrosion, and provide consistent performance, all while helping your brake system perform at its best. Whether that’s a glycol-based fluid or a silicone-based one will depend on your individual circumstances and preferences.

Remember that a high-quality brake fluid is only one component of a comprehensive braking system. Pairing your chosen fluid with high-quality brake pads and maintaining your entire brake system in good condition will ensure optimum performance and safety on the track.

In conclusion, as a true fanatic of track days or racing, don’t overlook the crucial role of the brake fluid in your Nissan GT-R’s performance. It might seem a minor detail compared to other aspects of your car, but it can make a significant difference in your track experience. So, dive in, do your research, and choose wisely! You, your Nissan GT-R, and your track day experience will be better for it.
