Even the tolerance level against the steam bubbles screams high safety. And lastly, you don’t need to indulge in frequent brake fluid changes.

What I’m about to discuss is not an error made by ATE. I see it more as an unfortunate government restriction. Even so, it’s worth mentioning. The color of the formula is not blue. And that makes the process of monitoring full flushes a lot harder.

    Pros

  • The ATE fluid improves pedal feel.
  • The increased boiling point offers peak performance.
  • It is not harsh on paint in case of spilling.

    Cons

  • The quantity is too low.
  • Not blue in color to make full flushes easier.

2. Castrol 12614 Dot 4 Synthetic Brake Fluid – The Best DOT 4 Brake Fluid for High Temperature

Castrol 12614 Dot 4 Synthetic Brake Fluid

Every best brake fluid article consists of at least two product listings by Castrol. Whereas this post has more than two! That’s how reliable and high-performing Castrol’s brake fluids are! So here’s the Castrol 12614 Dot 4 Synthetic Brake Fluid; created to withstand the high temperature of braking systems.

The thing about advanced, newly released cars is that they require fluid that has the ability to match up to their high standards. A large amount of heat generated by rotors of new cars demands the use of high-tolerance brake fluid. And that’s exactly what you get with the current pick. (Common brake system issues)

The braking response that the Castrol 12614 Dot 4 Synthetic Brake Fluid provides is more than just optimal. It guarantees road safety despite unforgiving surfaces or high speed. You can mix the formula with other DOT-rated fluids as well. It doesn’t give rise to incompatibility issues. Instead, the fluid provides smoother control and better response with every brake.

So for outstanding performance under high temperatures, you might want to check out the Castrol 12614 Dot 4 Synthetic Brake Fluid.

If you want me to give you one solid reason to go for this particular brake fluid manufactured by Castrol, here it is. The liquid excels at reducing moisture. With such an action taking place, the chances of corrosion formation get eliminated. In other words, your braking system and its components last longer than you can imagine.

The Castrol 12614 Dot 4 Synthetic Brake Fluid meets the highest of the highest standards alright. But it’s due to this quality only that the formula shouldn’t land on any painted surface. It doesn’t react so well at such times.

    Pros

  • The Castrol fluid improves pedal feel.
  • It reduces braking distance and increases braking response.
  • Moisture absorption capacity is very low.

    Cons

  • It is highly corrosive on painted surfaces.

3. Motul DOT 5.1 Brake Fluid – The Best Affordable DOT 5.1 Brake Fluid

Motul Brake fluid, DOT 5.1 (N-S) - 500ml

It’s time to discuss the highest-rated DOT 5.1 brake fluid, which coincidentally is also a budget-friendly pick. The Motul DOT 5.1 Brake Fluid works in all braking systems. It is among the very few liquids that have non-synthetic properties. But that doesn’t imply bad quality or poor performance. In fact, this best brake fluid is perfect for vehicles under normal weather and road conditions.

The thing that I like the most about the Motul DOT 5.1 Brake Fluid is its combination of high quality and low price tag. It’s because the majority of DOT 5.1 brake fluids, the good kind, are expensive. Even on this list. So it’s great to finally find a pick that’s priced more reasonably than the others.

Moving on, allow me to brag about the performance by asking you a question. Does your car demand high boiling temperature protection? If so, this is exactly what you should get. The absorption rate is also much lower compared to other Motul brake fluids.

It takes care of the large overheated brakes of trucks as well. Compatibility with DOT 4 and DOT 3 is not an issue either. And the same applies to daily car components. So you’re in for a smooth, flawless experience!

There’s no doubt about the fact that Motul manufactures high-quality brake fluids. In this particular case, the DOT 5.1 formula doesn’t fail at holding up to high temperatures like you would expect. Even though it’s one of the cheaper priced fluids!

Now let me tell you what happens to brake fluids when you open them up. Once the container seal is broken and the cap opened, the formula absorbs moisture present in the air. As a result of which it can go bad fairly quickly. So you might as well purchase limited quantity when you know you’re not going to use a lot of brake fluid at once. In that case, stay clear of the Motul DOT 5.1 Brake Fluid.

    Pros

  • The Motul fluid works well on high-performance vehicles.
  • It tends to last for a very long time.
  • Also suitable for the brakes of a mountain bike.

    Cons

8. Genuine Honda Fluid 08798-9008 DOT 3 Brake Fluid – The Best High-Performance DOT 3 Brake Fluid

Genuine Honda Fluid 08798-9008 DOT 3 Brake Fluid - 12 oz.

The product name has the word “genuine” in it. And upon testing, that’s exactly what the performance looked like. The Genuine Honda Fluid 08798-9008 DOT 3 Brake Fluid is a top quality formula. The kind that you can rely on since its manufacturer is none other than Honda.

Let me give you some useful information now. This best brake fluid offers the highest temperature and moisture tolerance in the current industry. The invaluable boiling point is above 400 degrees. Unbeatable at the moment!

What’s that one common issue of all DOT 3 brake fluids? It’s their high water/moisture absorption capacity. Is that correct? But that’s something you need not worry about in this case. Because Honda has included some additives, which serve as excellent antioxidants! To prevent rust and corrosion like no other option discussed in the article.

The brand understands, better than anybody else, how important it is to protect your investment. And based on that, they manufacture fluids that you can select without feeling challenged or confused.

I’m not just going to tell you to buy the Genuine Honda Fluid 08798-9008 DOT 3 Brake Fluid. I’m also going to discuss the reasons to do so. And the most important one has a lot to do with the innovative technology that Honda makes use of. In this case, it’s the presence of additives in the formula.

9. Motul MTL100949 8068HL RBF 600 Factory Line Dot 4 Brake Fluid – The Best DOT 4 Brake Fluid for Racing

Motul MTL100949 8068HL RBF 600 Factory Line Dot-4 100 Percent Synthetic Racing Brake Fluid - 500 ml

Some clutch systems and hydraulic brakes require synthetic fluid with a non-silicone base. If that’s what you’re dealing with, nothing fits the bill more than this particular option. The Motul RBF 600 Dot 4 Brake Fluid is specifically created to serve such a purpose. Plus, it’s a highly recommended product due to the high-quality of the formula.

But how is it an excellent choice for racing? The fluid can tolerate extreme temperatures. Thanks to the high wet and dry boiling point. So you can use it to fill up your racing clutch and hydraulic systems.

Along the same parallel, the increased level of wet boiling point is suitable for conditions like heavy rain. As a result of this, water absorption reduces to a large extent. And the outcome of that is less moisture in your brake system. So the components present inside are well-protected against corrosion. In fact, the optimal wet boiling point also takes care of vapor lock.

So if you want access to smooth, error-free braking experience, there’s no need to look any further.

Not many non-silicone based synthetic brake fluids perform as exceptionally as this pick. The formula is designed for nothing but high-temperature resistance. This kind of superior thermal resistance is the result of the generous boiling point.

Unfortunately, there’s bad news that might even seem like a deal-breaker. The product I’m currently reviewing fails at enhancing pedal feel. So if the pedal feels spongy, it’s going to remain that way even after using the formula.

    Pros

  • The Motul fluid enables effective brake.
  • ​Even under extreme circumstances, it exceeds standards/expectations.
  • Thermal resistance capacity is quite high.

    Cons

  • It does nothing to improve pedal feel.

The connection between liquids and cars is not only important but necessary too. Be it oil and gas to get the engine to run smoothly. Or coolant to prevent the car from heating up excessively. Or the best brake fluid to avoid potential brake system failure.

What happens when you brake? The mechanism generates heat, right? So to rule out the possibility of overheating and likely brake failure, your car requires brake fluid. It keeps all the parts in there cool. While also making sure that those brakes function seamlessly. In fact, brake fluid helps with lubrication as well. And that, in turn, prevents corrosion.

So using the best brake fluid means doing everything in your power to ensure that the system runs safely and smoothly.

How Do Brake Fluids Work?

best-brake-fluid-6

The braking system of every car contains a hydraulic fluid. Upon pressing the pedal of the brake, the liquid flows into a cylinder before reaching down to the metal or rubber pipes. This is where the wheel cylinders and brake calipers are located. And they are responsible for actuating the brakes.

The fluid initiates the transfer between the pedal force and brake caliper since it cannot be subjected to compression. As a result of which it provides a consistent and solid pedal feel.

How to Check Your Car's Brake Fluid?

Moving on, let’s find out how brake fluids can generate brake fade.

How Do Brake Fluids Lead To Brake Fade?

best-brake-fluid-7

Brake fluids are glycol-based, meaning they have hygroscopic properties. In simple words, they absorb moisture present in the atmosphere. So it doesn’t sound like a surprise to know that, over a period of time, the formula can also absorb water through the pervious walls of the rubber equipped brake hoses. And the water absorption is not minimal; brake fluids have the ability to absorb moisture as much as 13 percent of their total weight. Over a span of two years!

Now let’s try to understand the reasons as to why this moisture absorption is bad for the braking system. You cannot compress fluids, right? On the other hand, gasses can be subjected to compression.

When the used brake fluid takes in water, the brakes tend to get hot. So when the temperature rises over 100 degrees Celsius, the water turns to steam. And that, in turn, turns to gas, which is susceptible to compression. So at such times, the soft pedal feel is a result of your foot performing the compression action.

More often than not, road car owners neglect the importance of brake fluid and the overall braking system. That means older vehicles have a lesser chance of being filled with fresh brake fluid. And this affects the performance of the invaluable braking system on track.

Understanding Dry Boiling Point and Wet Boiling Point

best-brake-fluid-8

Brake fluids have a wet/dry boiling point stated in their specifications. The dry boiling point rating is for fresh fluid while wet is applicable for saturated fluid.

When brakes bleed frequently, it’s the dry boiling point that matters the most. But the wet boiling point is more crucial if you’re in the habit of not changing the fluid as often as you should.

Another thing to keep in mind is that motorsport demands a higher brake fluid boiling point charge. And this is the major topic of discussion and distinction when it comes to racing brake fluid vs regular brake fluid.

Difference Between DOT 5.1, DOT 5, DOT 4, and DOT 3 Brake Fluids

Department of Transportation; that’s the full form of DOT. And it’s this particular entity that sets the standards for the best brake liquid. DOT 5.1, DOT 4, and DOT 3 are glycol-based formulas. And the primary difference between them is associated with their brake fluid boiling point charge.

The minimum wet and dry boiling points are what DOT fluid manufacturers have to keep in mind to meet the required standards. These are nothing but minimum temperatures the liquid performs at prior to boiling, which tends to result in brake failure.

Here’s a chart listing the standard temperature level of the different brake fluids and their

Brake Fluid

Dry Boiling Point

Wet Boiling Point

DOT 5.1 fluid

270 degrees Celsius

190 degree Celsius

DOT 5 fluid

260 degrees Celsius

190 degree Celsius

DOT 4 fluid

230 degree Celsius

155 degree Celsius

DOT 3 fluid

205 degree Celsius

140 degree Celsius

Now you should also know that DOT 5.1, DOT 4, and DOT 3 are all compatible together. Thanks to their glycol-based nature. So you can mix them without causing any harm to the braking system. The only thing to remember is that DOT 5 is the odd one as it has a silicone base. So avoid mixing it with other glycol-based DOT formulas.

I would also like to bring another popular misconception to your notice. That DOT 4 is not compatible with DOT 5.1 and vice versa. You don’t have to flush out your DOT 4 system when upgrading it to DOT 5.1.

EndNote

My Choice: ATE 706202 Original TYP 200 DOT 4 Brake Fluid

My goal was to provide you with a better understanding of the best brake fluid. It’s because not all formulas have the same qualities. So it’s important to know the difference between brands and their creations. Brakes are not to be neglected; you should keep that in mind too.

With the same perspective, your braking system demands a high-quality, long-lasting formula. Such as the ATE 706202 Original TYP 200 DOT 4 Brake Fluid. Its remarkable water locking ability doesn’t decrease the invaluable boiling point to a great degree. The liquid is non-foaming during the bleeding and filling process. Even corrosion protection is a part of the deal. Thanks to the use of selected additives by ATE.

With a high tolerance level for safety and infrequent changes, this best brake fluid exceeds all expectations. In practical terms, it’s also ranked as the best DOT 4 brake fluid for motorcycles.
