4 Best ATV Brake Fluids

When it comes to maintaining your ATV's performance and safety, one essential aspect is ensuring you have the best brake fluid available.

Brake fluid plays a crucial role in your ATV's braking system, as it transfers the force created when you press the brake lever to the various components of the brakes.

You can experience smooth braking power and maintain optimal trail safety with the right brake fluid. We have found five of the best brake fluid options for ATV riders.

1. Motul 5.1 ATV Brake Fluid

The Motul 5.1 ATV brake fluid is popular with its high rating and glycol-based formula. It has a higher boiling point than DOT 4 and is packaged with nitrogen instead of air.

This is the ideal brake fluid for street-use ATVs. It will work best with larger models because of the higher boiling point. It also increases vehicle stability over the long term because it lasts much longer.

The superior thermal stability of Motul 5.1 helps maintain optimal operating temperatures to provide a greater degree of protection against wear caused by heat build-up. It’s also DOT 3 and DOT 4 compatible.

This product offers superior braking performance under extreme pressure thanks to its strong anti-friction additives. It also does well to reduce the risk of corrosion.

2. Wagner DOT 5.1 Brake Fluid

Another excellent option for ATVs and UTVs is the Wagner DOT 5.1 Brake Fluid. With all the benefits of glycol-based fluids, this one also offers a high boiling temperature, making it a reliable choice.

This means it resists boiling under extreme conditions, preventing brake fade and ensuring consistent performance. This is particularly important for ATV riders who encounter challenging terrain where stopping power is critical.

It is compatible with all ABS and non-ABS braking systems, which is a significant advantage for ATV riders who use a wide range of braking systems. It also meets or exceeds DOT 3 and DOT 4 specifications, making it a versatile option for different types of vehicles.

One more unique feature of this product is its anti-corrosion properties. It contains a special blend of additives that help protect against rust and other forms of corrosion, which is essential for ATV riders who use their vehicles in harsh environments.

3. Maxima Hi-Temp Racing Brake Fluid DOT 4

The Maxima Hi-Temp Racing Brake Fluid DOT 4 is an ideal choice for ATV riders who demand high performance and reliability in their brake fluid. One of the standout features is its high boiling point, which is crucial for off-road riders who push their vehicles to the limit.

It is also designed with a unique blend of additives that improve its resistance to moisture, ensuring reliable performance in wet conditions. This is particularly important for off-road riders who encounter water crossings or muddy terrain.

Overall, this is one of the most versatile choices for riders using different ATVs or other vehicles with different braking systems. It lasts longer, protects the braking system, and improves braking performance.

4. Polaris DOT 4 Brake Fluid

Last but not least, we have the Polaris DOT 4 Brake Fluid. It offers fantastic boiling points, wet or dry, ensuring your brakes remain fully responsive in various riding situations.

This product would work great with Polaris ATV models. It’s a specially designed ATV-specific brake fluid. The DOT 4 spec is ideal for high-temperature applications without sacrificing durability.

In addition to its performance benefits, Polaris DOT 4 Brake Fluid is also easy to use. It comes in a convenient bottle with an easy-pour spout, making it simple to add to your ATV's braking system.

Types Of ATV Brake Fluids

In this section, we will discuss the various types of brake fluid available for ATVs. It's important to know the differences between each type to ensure proper maintenance and safety of your off-road vehicle.


DOT 3 brake fluid is a common glycol-based fluid used for most vehicles in the United States. It has a lower boiling point than DOT 4 and DOT 5.1 fluids.

 DOT 3 brake fluid is compatible with several ATV brake systems. However, better choices for hard off-road usage or extreme conditions may exist. It is essential to consult your vehicle's owner's manual for the factory-recommended brake fluid type.


DOT 4 brake fluid is another glycol-based fluid for vehicles with higher performance requirements. This type of brake fluid has a higher boiling point compared to DOT 3, which makes it more suitable for ATVs experiencing high temperatures or heavy usage.

Many European vehicles, ATVs, and UTVs use this fluid as their default factory recommendation. Always check the owner's manual for your ATV to determine the best brake fluid type.

DOT 5.1

DOT 5.1 brake fluid is a high-performance glycol-based fluid with similar properties to DOT 4 but with an even higher boiling point. This makes it an excellent choice for ATVs and UTVs subjected to extreme conditions or heavy usage.

It can offer superior performance compared to other brake fluid types, and it is packaged with nitrogen instead of air, further increasing its boiling point.

How to Check and Change ATV Brake Fluid

Follow these steps to check and change the ATV brake fluid. It’s a tricky process, so proceed with caution.

Checking Fluid Level

It's essential to check your ATV's brake fluid level regularly. Locate the brake fluid reservoir, usually found on the handlebars or under the seat, and make sure the fluid is between the minimum and maximum marks.

If the fluid level is low, this usually indicates a problem. Now it’s time to investigate to see why fluid levels are dropping.

Bleeding the Brakes

After changing the brake fluid, it's crucial to bleed the brakes to remove any trapped air. Air bubbles can lead to reduced braking performance, so follow the proper bleeding procedure.

The fluid will become more saturated if you don’t bleed the brakes. This results in the brakes slowly decreasing in performance. After enough time, the ATV will not stop fast enough and more pressure must be applied for the brakes to respond.

Changing Brake Fluid

Changing ATV brake fluid starts with first removing the old fluid. You'll need to open the bleeder valve on all brake calipers and place a container under each caliper to collect the old fluid as it seeps out.

Once the fluid turns clear, tighten the valve and fill the reservoir with new brake fluid. The master cylinder is smaller on an ATV, making it harder to refill the fluid and bleed the brakes.

Key Takeaways

  • We recommend the Motul 5.1, Wagner 5.1, Maxima Hi-Temp Racing 4, and Polaris DOT 4 brake fluids for ATV owners.
  • DOT 3, DOT 4, and DOT 5.1 can be used with ATVs. However, we’d only recommend using DOT 4 and DOT 5.1.
  • Always check the fluid levels, bleed the brakes, and correctly add the new fluid when changing it. Typically low brake fluid means there is damage or a leak.
