Improve your driving experience with the leading brake fluids in 2022 that help your car’s brakes continue working effectively and efficiently. The saying “better safe than sorry” always rings true, especially in the case of our rides. Brakes are an essential component in every vehicle. And brake fluid is like their lifeblood. Changing it every year or two will save you a ton of headaches, and it may even prevent an accident! Confused? Well, we’ve made this guide that will tell you all about the finest brake fluids in 2022 and how to buy this essential hydraulic fluid for your car.

Brake fluid is a chemical solution that most modern vehicles use in their braking systems. These vehicles can range from cars and motorbikes to trucks and even lorries. You see, it would take a lot more to stop your vehicle than just your foot on the brake pedal if it wasn’t for this liquid. But brake fluid can get old and dirty over time, just like your car’s oil. 

When it does get old and yucky, a lot of problems start to come up. For instance, your brakes may feel mushy or your car may start to take longer to come to a complete stop. This can be pretty annoying and even downright dangerous. So, you should be replacing the brake fluid in your car or motorbike regularly.

Buying Guide: Brake Fluids 

You must consider various factors before buying a new braking fluid for your car. Luckily, we researched for you and put together this guide:

Breaking Down the Technical Terms Related to Brake Fluids

First thing’s first, let’s explain the meanings of some of the technical terms you will come across when shopping for brake fluids:

DOT ratings

You will come across DOT ratings a lot when looking for brake fluids. A DOT rating is given to a brake fluid based on its wet and dry boiling points. These ratings must be kept in mind since they determine whether a brake fluid meets the required minimum performance criteria or not. Generally, the higher the DOT rating and boiling points are, the better fluid life and performance you get.

The four most common ratings are DOT 3, DOT 4, DOT 5, and DOT 5.1 brake fluid. DOT 3, DOT 4, and DOT 5.1 are all non-silicone-based brake fluid types. These three DOT-rated brake fluids are the ones that most modern cars use. DOT 5, on the other hand, is silicone-based and is not commonly used in regular cars. 

Fluid life

Fluid life is another commonly used term in the world of brake fluids. As its name suggests, this number represents how long your brake fluid will last you before it needs to be replaced. The fluid life is usually stated in miles, such as 40,000 miles or 50,000 miles. 

Some brands may also just tell you how many years you should use their brake fluid before replacing it — kinda like an expiry date. You’ll usually find these numbers on the label of the fluid container. 

What to Look for When Buying Brake Fluids?

Here are some things to look out for when shopping for brake fluid to help you get a great deal:


You should only use a compatible DOT-rated brake fluid with your vehicle. This is because using a brake fluid with an incompatible DOT rating can cause serious harm to your vehicle’s brake system. 

It may even make your car’s brakes less effective. You can check the compatible DOT ratings of your car or motorbike by going through its handbook. You may also consult your mechanic or the guy over at the local DMV. 

Bottle size 

Next, you should also consider the bottle size when buying brake fluid for your vehicle. It is no fun having to order more later because you didn’t get enough the first time around. So, check your vehicle’s handbook to determine how much brake fluid it will need and get the recommended amount. You can also buy extra if you’d like to have some in your spare storage. 

How We Choose the Top Brake Fluids?

To ensure that you get the best possible brake fluid for your vehicle, here are some things we took into account when choosing our top picks:

Easy storage

All the brake fluids we chose are super easy to store. The bottles they come in have a compact shape and are easily stackable in a box. You just need to close their lid tightly, and you are good to go. Oh, by the way, since we’re on the topic of storage, always remember to store brake fluids in a dry place since they absorb moisture crazy fast. 

We also ensured that the bottles we chose provided a spill-free pouring experience, so the chances of a spill happening are minimized. You can read the product reviews to get a better idea of how easy it is to store your braking fluid. 

High boiling points

A higher wet and dry boiling point means you get better fluid life and performance. This is why the brake fluids we chose had higher boiling points than the minimum that their DOT ratings require. This ensures good quality and longer fluid life. You can usually find the boiling points of brake fluid on the bottle’s label or the product description.

What to Keep In Mind When Changing the Brake Fluid in Your Vehicle?

Although it is pretty easy to change the brake fluid in your vehicle, there are still some things to keep in mind to make the process smoother and hazard-free:

Reduce exposure to air

The less exposure to the air your brake fluid has, the longer it will last you. So, it is best to minimize this exposure by working quickly and putting the lid on the fluid container once you are done. Also, double-check the lid is closed properly before chucking the container into the storage. 

Prevent spillage on your vehicle’s body

Brake fluids tend to be pretty corrosive. This is why you should avoid spilling it on the body of your car or its engine. If a spill does happen, wipe the liquid away quickly. It is also a good idea to wear gloves when working with brake fluid to avoid exposure to your skin.

Brake Fluid FAQ’s

Let’s answer some brake fluid-related FAQs to address any questions you may still have:

Q: Can I mix brake fluids?

Whether or not you can mix brake fluids varies from product to product. You can check the directions on the label to ensure if it’s allowed or not. Keep in mind, however, to never combine a DOT 5.1 brake fluid with other types since it is not suitable for experimentation.

Q: When should I replace my car’s brake fluid?

You should replace your car’s brake fluid if you hear any weird sounds, get any burning smell, or feel like the brake is a bit mushy. You should also change the brake fluid once it is older than its recommended fluid life. 

Q: How do I check my car’s brake fluid level?

You can easily check your car’s brake fluid level using the markings on the reservoir. Ensure the fluid level is within the minimum and maximum markings on the reservoir.
