Top 9 Best Brake Fluid For Your Consideration In 2021 Reviews
1 Motul Racing Brake Fluid – Best Brake Fluid for Drag Racing
If you love going fast, and we mean Fast and Furious style, drifting up to the parking lot at work, because you are five minutes late, then Motul’s DOT-4 brake fluid might be for you. Racing is even in the name!
All jokes aside…
Motul’s DOT-4 racing brake fluid is designed for high-performance cars, sports cars, and cars who frequently drive routes that require a lot of braking, like mountain roads or urban stop-start driving for prolonged times.
The DOT-4 classification means the oil has a boiling point of 594 Fahrenheit, which makes it well suited for racing environments where the brakes will not only be used a lot but also pushed to their extreme. It’s not cheap, but the same goes for sports cars. So, go ahead, racecar junkies, and get your fix today.
- Low volatility rate.
- High boiling point.
- Works as a friction modifier.
- Advised to be used only with race cars.
2 Castrol SRF Racing Brake Fluid – Best Castrol Brake Fluid
If you want to keep your car’s brakes well lubricated and maintained, then look no further than Castrol’s Racing Brake Fluid. This brake fluid was designed with rallying and racing in mind, using an exclusive European formula that is kept secret. The formula has high boiling temperatures with a wet boiling temperature of 270 degrees Celsius and 310 degrees Celsius dry boiling point.
Castrol’s SRF Racing Brake Fluid exceeds not only DOT-3 standards but also DOT-4 standards. This makes it an exceptionally well-made brake fluid, with a low water content and high boiling temperatures.
- Superior quality.
- Anti-vapor lock characteristics reduce heat-related fluid failure.
- Not really made for ‘normal’ cars.
3 ATE Original Racing Quality DOT 4 Brake Fluid – Best ATE Brake Fluid
ATE is well known among racing enthusiasts as one of the best manufacturers of vehicle lubricants and oils, and the TYP 200 racing brake fluid is no exception.
The brake fluid is classified as a DOT-4 brake liquid, which means it has a higher boiling temperature than lesser brake fluids. It also means it doesn’t absorb water as easily through the braking system, making it last longer and keeping your equipment corrosion free.
What does that mean for you?
According to ATE, this means the brake fluid can be used for up to 3 years before it would need changing, which is exceptional for brake fluid. Not only that, but it doesn’t break the bank, making it an exceptional deal for such a great product.
- Long lasting.
- Protects against rust.
- Only works with vehicles that support DOT-4 braking fluid.
- This product has been discontinued.
4 Motive Products Brake Fluid Catch Bottle Kit – Best Simple Brake Fluid Change Accessory
Replacing any sort of hydraulic fluid can be a dirty and difficult situation, especially with the wrong equipment. The brake systems in cars are hydraulic, which can lead to a serious mess if replaced incorrectly.
Motive Products sell these brake fluid catch bottles to ease the pain of draining brake fluid. The long hose and wired lanyard make bleeding the brakes as easy as attaching the bottle and draining the brake fluid, no fuss, no mess.
The hose is clear, making it easy to see the fluid and if any bubbles are formed. The bottles are also clear, making it easy to see when it’s full. It’s also easy to see any dirt or particles in the oil.
Before putting new brake fluid in, it’s a good idea to invest in one of these to make draining the brakes much less of a hassle.
- Very simple to use.
- Reduces mess and makes for an easy cleanup.
- Clear design ensures you know exactly what’s going on.
- Not brake fluid, but an excellent buy for your next fluid change.
5 Prestone Synthetic Brake Fluid – Best Dot 3 Brake Fluid
This brake fluid is rated DOT3, which means it’s still a high-performance brake fluid, but won’t be as great as DOT4. Like DOT4, DOT3. Even so, it still boasts some decent anti-vapor characteristics. This helps keep the fluid usable over longer periods of time, keeping any vapor and liquid build up to a minimum.
DOT3 Fluids have a lower boiling point than DOT4, although Prestone’s brake fluid does come close. Thus, the largest selling point would be its price. Being DOT3 means that it is a fair bit cheaper than most DOT4 brake fluids, but it is more expensive than most DOT3 fluids.
Is it right for you?
What we have here is a bottle of brake fluid that sits right in between the DOT4 and DOT3 performance and price, which is good or bad, depending on what you need it for.
If you want great performance, but don’t need the high performance, sports car DOT4 brake fluid, then stick with this. It’s reliable, better than most DOT3 brake fluids, lasting much longer, and stays clear for longer as well.
- Lasts longer than most DOT3 fluids.
- Doesn’t offer protection against corrosion.
6 Finish Line High-Performance Brake Fluid – Best Bicycle Brake Fluid
Finish Line began as a small production and development company before quickly needing to expand their product line. They quickly built their brand around bicycle care products in the ’80s. In the 90’s they realized their international potential and broadened their horizons, exporting to many countries, including German and England.
Their range of bicycle care products is all high quality and affordable. Finish Line’s high-performance brake fluid has been designed with bicycle hydraulic disk brake specifically in mind.
What else makes it special?
This brake fluid does a great job protecting your brakes from foaming up or overheating when used a lot. The brake fluid is a high-performance DOT5.1 mix, which offers excellent levels of brake response and pad retraction. The price is reasonable, considering the no compromise, cutting edge technology bottled up here.
This liquid can be used on cars as well. DOT5.1 should not be mistaken for DOT5. DOT5 is a silicon-based fluid, which has different properties and does not mix well with the glycol-based DOT4 and DOT5.1. Most cars can use DOT3, DOT4, and DOT5.1, although the latter two are better and high-performance focused.
What’s our final verdict?
The DOT5.1 brake fluid is much more expensive, almost double that of certain DOT4 and DOT3 brake fluids, which does make it difficult to recommend for cars.
- Reliable and high-performance.
- Bottle isn’t great; fluid will only last about a month once opened.
7 Bel-Ray Silicone Brake Fluid – Best Mid Range Brake Fluid
Bel-Ray’s DOT5 brake fluid cannot be used with any vehicle and is specifically designed for vehicles that use DOT5 brake fluid like certain superbikes and cruisers.
DOT5 is not a glycol-based brake fluid but instead uses silicone as the base. This makes it water-resistant, meaning it will never absorb any water. It also doesn’t cause any damage to paint, but if used on a system that requires DOT4 or 3, it could possibly damage the seals, resulting in your brakes leaking.
Is it right for you?
DOT5 was made for vehicles and applications where moisture in the system is almost a certainty, like military vehicles or antique cars and bikes. Older, antique cars won’t be used as much as a regular vehicle, meaning the fluid would be stagnant for long periods of time, making it susceptible to moisture, which is why silicone is used for its water-resistant properties.
- Highly water-resistant.
- Great for antique bikes and cars.
- Lasts a very long time.
- More expensive.
- Cannot be used in most vehicles.
- Cannot be mixed with DOT3 or DOT4 fluids.
8 Endless Racing Brake Fluid RF 650 – Best Premium Brake Fluid
Endless Racing’s brake fluid is used all over the world for Formula 1 racing, World Rally Championship events, and even the Paris-Dakar Rally. It is one of the most recognized and widely used high-performance brake fluids in the world.
Marketing would have you think that this brake fluid can only be used for racing cars, but it can also be used on everyday vehicles, especially if you enjoy driving like a rally driver on your daily commute.
What else do you need to know?
This is a DOT5.1 brake fluid, so it can be mixed with DOT4 fluids, but it’s better to completely drain a system and filling up with brand new liquid, instead of adding to it.
The mixture here is quite thick, resulting in a more responsive but stiffer feeling brake pedal, perfect for racing, but it might not suit casual driving in town. This brake fluid has an extremely low freezing point at -40 degrees Celsius, making it perfect for people driving in extremely cold conditions.
- Excellent, fast braking.
- Extremely low freezing point.
- Durable and long lasting.
- Might not be well suited for day-to-day use.
9 MAG1 120 Premium Brake Fluid – Best Value for the Money Brake Fluid
MAG1’s premium brake fluid is a DOT3 fluid, which comes with a much lower price than DOT4 and DOT5.1, but with a lower boiling point. DOT3 liquids are perfect for everyday use with normal cars.
Under normal circumstances, brakes will never apply enough pressure or friction that the fluid would ever reach boiling point. Thus, most people opt for DOT3 liquids for their cars unless they own high-performance sports vehicles that require DOT4.
Now, that’s value…
MAG1’s fluid is decent and gets the job done without too much fuss. It is priced well and comes in large bottles, which might be a problem for some, only looking to use it on one vehicle. Because brake fluid does not store well, especially DOT3, which will absorb moisture faster than DOT4, large quantities will be wasted unless you own a shop that changes brakes regularly.
There isn’t much more to say about this brake fluid; it’s a DOT3 brake fluid that does exactly what it should.
- Great for normal cars.
- Bottle is too much for single use.
- Has a lower boiling point than DOT4 fluids.
Best Brake Fluid Buying Guide
There are quite a few things to consider before purchasing brake fluid. So, here are some things to keep in mind before spending your hard-earned cash…
On this list, we mentioned DOT3, 4, 5, and 5.1 fluids. Each of them has different characteristics, although the biggest difference is between DOT5 and the rest. DOT5 is a silicone-based brake fluid made for applications where moisture is a given. Silicon is much more water-resistant than the glycol-based brake fluids, DOT3, 4, and 5.1.
The differences between the rest are mostly the dry and wet boiling points. DOT3 has the lowest amount of moisture resistance, which makes its wet and dry boiling temperatures lower than DOT4 and DOT5.1.
Does it mix well?
The glycol-based liquids can easily be mixed between each other for the most part. That means a DOT4 and DOT5.1 fluid can be mixed with each other, although you are better off completely draining the system before adding new oil. DOT5 cannot be mixed with any of the other fluids because silicon and glycol don’t mix well.
Some fluids are clear, and some are colored. Some people like to interchange between two different brake fluids on color alone. It allows you to see when the system has been fully drained, and the new liquid is in the system.
DOT4 does well resisting corrosion due to its better anti-vapor properties than DOT3. This means that DOT4 protects the parts on the inside from moisture that might cause corrosion, which is why it is used in expensive sports cars. If possible, getting a DOT4 liquid is preferred over a DOT3, specifically due to this aspect.

So, what is the Best Brake Fluid?
Our top pick has to be the…
It is the perfect mix of quality and price. And it is a DOT4 brake fluid, which means it is far superior to DOT3 fluids. It has a high boiling point, wet and dry. There is a reason Motul is seen and used so much in the racing industry because it offers excellent performance at a fair price.
