How to Choose the Best Brake Fluid

Choosing the right brake fluid can be confusing. If you’re not sure what you’re looking for, it’s honestly a bit overwhelming. If you’re asking yourself, what’s the best dot 4 brake fluid?, never fear. We’re here to help. We researched the top rated products to help you figure out which one is best for your vehicle. Before we get into our reviews, let’s take a look at the key features you need to know about brake fluid.

Best Brake Fluids

DOT: DOT stands for Department of Transportation and is a standardized way to classify these fluids. DOT 3 and DOT 4 are for passenger cars and trucks while DOT 5.1 is for racing vehicles. DOT 5 is used for military vehicles.

Best Brake Fluids

Synthetic: There’s some debate over this. Some people only classify silicone based fluid as synthetic and glycol based formulas as non-synthetic. Popular opinion seems to be that all brake fluid is synthetic since it’s not found in nature. We agree.

How to Choose the Best Brake Fluid

Non-Silicone: This is pretty important. DOT 5 fluids are silicone based and those are the ones that are used in military vehicles. So, for passenger vehicles (DOT 3 and 4), you can’t use a silicone based fluid.

Best Brake Fluids

Mixable: Here’s the deal. You can mix down but not up. So, if your car uses DOT 3 and you want to add DOT 4, go ahead! But don’t add DOT 3 if your brake system uses DOT 4.

Best Brake Fluids

Package Size: These vary from 16 to 32 ounces. Some of these last a long time before needing changed. If that’s the case, smaller bottles are better so the unused fluid doesn’t sit on a shelf or go to waste.

Money Back Guarantee: Unfortunately, offering a money back guarantee isn’t something that most of these manufacturers offer. But once you understand that brake fluid isn’t as complicated as you might think it is, that makes sense.

Top 10 Products

Now that you know more about brake fluid, let’s move into our reviews. If you’ve used the best brake fluid tester and know it’s time for a change, make sure to check out our top and budget picks to save some time. They’re right at the top of the list and give you some idea of the range that’s available. Stick around if you have time, we really cover a little bit of everything. Ready? Let’s get to it.

ATE TYP 200 Brake Fluid

Top Pick
Our top pick isn’t just the best brake fluid we found, it’s also the best dot 4 brake fluid for motorcycles. ATE TYP 200 Brake Fluid has excellent water locking properties that cause a minimal decrease of the boiling point. Specifically, it has a dry boiling point of 536 degrees Fahrenheit and a wet boiling point of 374 degrees Fahrenheit. What does that mean? The dry boiling point is measured when the fluid is fresh from the bottle; wet is measured after it’s absorbed water over time. The faster the wet boiling point deviates, the sooner you’ll need to replace your brake fluid. With this best motorcycle brake fluid, you can go about 3 years, which is pretty great. It provides excellent corrosion resistance and is non-foaming to prevent air bubbles from forming.

Motul DOT 5.1 Brake Fluid

Budget Pick
Motul Dot 5.1 Brake Fluid is the best cheap brake fluid we found in our research. It’s a non-silicone fluid that’s safe to use in DOT 3/4 systems. The dry boiling point is 516 and with a wet boiling point of 365 after one year of use. Typically, this product will last longer than a lot of DOT 3s and 4s. Because it has such a high boiling point, it stays stable over throughout its use. This fluid is 100% synthetic and can be used with a lot of different brake and clutch systems. It’s actually specifically designed for anti-lock brake systems. While some people prefer this fluid for racing but it’s approved for street use so you can use it in any compatible system.

Honda DOT 3 Brake Fluid

Next up in our brake fluid reviews is the Honda DOT 3 Brake Fluid, specifically made for use in all Honda models. This is actually the exact same fluid that your vehicle came with when you bought it. It’s called an OEM fluid, meaning “original equipment manufacturer”. The best thing about using an OEM like this one is that there’s no guessing whether or not it’s going to work in your vehicle. It’s simple. If you have a Honda, this is the perfect fit. Now, you might be wondering if you have to have a Honda to use this product. The answer is no! As long as your vehicle’s brake system is compatible with DOT 3 fluid, this will work just fine. If you do have a Honda, though, using this fluid takes away any of the guesswork.

Motul Factory Racing Brake Fluid

Our choice for best racing brake fluid is this one from Motul. It’s made for hydraulic actuated brake and clutch systems and is extremely stable and we also think it’s the best high temp brake fluid. This means it has better aerodynamic performance which makes it ideal for racing. The dry boiling point is 594 degrees Fahrenheit, wet is 401. What you need to pay attention to with this fluid is how high the wet boiling point is. That’s how it will perform after it absorbs some water from just being in the braking system. That’s a pretty impressive temperature that will keep your braking system running very efficiently even in extreme conditions. While this is a great choice for racing cars at the track, it will degrade pretty quickly when used for everyday driving on the street.

Castrol Synthetic Brake Fluid

Castrol Synthetic Brake Fluid is up next and it our pick for best brake fluid for BMW. It’s actually formulated to suit Audis, Jaguars, Porsches, and other high end, modern vehicles that use high temperature systems. This DOT 4 fluid surpasses all government requirements. It maintains a higher boiling point than most brake fluids which helps your system run smoothly even in extreme conditions. Because moisture is always getting into the system, braking systems are always at risk for corrosion. This fluid protects against it, specifically from the problems caused by chloride and zinc. It’s great for giving some protection against the constant stopping and starting that most cars go through in a regular commute. You can mix this fluid with conventional fluids, too, so no need to worry when adding it to the system for the first time.

And don’t worry about mixing, it’s compatible with other DOT 3 brake fluids, too. This one has a lot of benefits in addition to keeping the system cool even under heavy braking. What do we mean by that? It also prevents the seals from hardening or softening and acts as an excellent lubricant. That’s not all, it even protects your braking system from rust and corrosion.
