Best DOT 4 Brake Fluid for Your Cars (Review and Buying Guide)

It's a widespread misconception that a vehicle can run just fine only on its fuel. Perceptions like these not only reduce your vehicle's potential and lifetime but, sometimes, also leads to some catastrophic accidents. The gas or other fuel you're feeding your car produces the energy to run your automobile. But a lot is going inside the system more than generating power. For instance, the brake on your vehicle is a hydraulic system, and hence it requires brake fluid to operate correctly. Therefore, for such a crucial mechanism to function correctly, choosing the Best DOT 4 Brake Fluid is a critical necessity.

In 1914 American automotive legend, Frederick Duesenberg developed the first hydraulic brake system, and today’s most used automotive brake fluid are silicone based DOT 5, DOT 4 and glycol based brake fluid DOT3. The uses of synthetic brake fluid are increasing drastically in the market. According to Global Brake Fluid Market Insights, the market size of automotive brake oil will raise from 800 million USD to 943 million USD at a CAGR of 2% in the period 2019- 2026.

Unfortunately, due to various misconceptions and lack of knowledge, car owners often ignore or overlook the significance of the best brake fluid. It often leads to many terrible incidents like brake failures, permanent damage to the system, brake pads damage and so on.

Now, considering these parameters, you might be confused about switching to the top rated DOT 4 fluid brands for your vehicle. If that's the case, then you need not worry anymore as we got your back. Here we have added a detailed walk through

Choosing The Top Rated Best Brake Fluids : Things to Consider

1. Compatibility with Vehicle

What is the type of your vehicle? Is it an everyday car or is it a racing or sports car or is it a bike? Is it a lightweight vehicle or a heavy one? Not all brake oils support every type of vehicle. So, it's better to choose one that suits your vehicle the best. Brake fluid for a bike may not do well with an SUV as they are very different, hence require different specifications of fluids.

So, choose the best one that is well compatible yet not overkill for your type of vehicle. Read the manufacturer's instruction guide to know if the fluid is well suited for your type of vehicle. That's the very first thing to consider.

2.  Material

The material of the best brake fluids is the second most important thing to consider. The longevity of the fluid depends a lot on its materials. For example, the liquid synthesized with more premium materials is more durable than the ones made out of cheap materials. But note that having premium materials also raises the price of the oil.

Especially if you are into sports like racing, the material of your DOT 4 fluid is one of the first things to consider as your vehicle's performance, and safety will depend heavily on this parameter.

3.  Additives

The top rated brake fluid dot 4 oils contain extra additives that grant the liquid some effective functionalities like corrosion prevention, improved thermals, etc. Perks like these enhance the overall efficiency of your brake pad function and also help the fluid to last longer.

Cheap and regular fluids typically lack these extra features and sometimes damage the system itself. That’s why it’s wiser to choose one that has effective additives that result in some very useful features.

4. Boiling Point

You may not even notice, but due to the constant and rapid hydraulic operations, a lot of heat is produced in the system. This heat in times makes the brake oil fade away. In fact, it's one of the critical reasons why you need to change the fluid. Keeping that in mind, the Lucas oil has a very high boiling point, which gives the oil more tolerance to heat. It makes the fluid fade much slower and takes a longer time to decay. A good brake oil outlasts regular ones even by years just because it has a higher boiling point. A brake fluid reaches wet point when it has 3.7 percent water content by volume. If you're into Power sports, the necessity of a higher boiling point is crucial. Either way, it's always safer to choose a brake fluid with a high boiling point.

5. Your Budget

Your budget affects your choices a lot. If you have a decent budget, you can go for even the most expensive liquids. But if you're running a little low, the list of what you can get gets shortened. Although brakes fluids are not that expensive if budget is really the case, then you need not panic. There are still some very fresh brake fluid that comes at a very low price. These fluids are also good and effective, and sometimes all you need.

So, choose the best one that is in your budget. Sticking to what you need rather than what you can get can sometimes save you a lot of money. Thus, brake fluid price is a vital factor to choose the suitable one. You don't typically need a race-grade oil for your little everyday car. That'd be both an overkill and an extra expense.

6. Your Location

The brake fluid of your choice may not be available in your location. Check first if the one you choose is available in your nearby stores. If not, you may have to buy it online. Make sure that the online store is trusted with good reviews to avoid scams.

Always consider these parameters when choosing the best oil for your vehicle. If the one you choose satisfies all of the parameters mentioned above, then congratulations! You just found the best match for your beloved automobile.

Why choose the best DOT 4 brake fluid 

You may wonder that engine fuel is important as it runs the engine but why brake fluids? What kind of liquid do I need? What makes them necessary or why you should always choose the best brake oil for your vehicle braking system. Let us break it down for you. You see, unless your car is an electric vehicle that uses hydraulic actuated brake, and you'll need hydraulic fluid to keep the system operational. Brake oil acts as the hydraulic to run the system.

A bad brake fluid decays very fast and can't tolerate higher temperatures produced during the brakes. It also doesn't come with additional protective features like anti-foaming, anti-corrosion, and so on. On top of that, bad fluids may even hamper your vehicle's brake system and brake line that will jeopardize the safety and performance of your vehicle. It often results in brake failures during pressing brake pedal leading to catastrophic accidents that injure thousands of people each year. Many even lose their lives.

Again, as inadequate oils in brake fluid reservoir is not safe, you'll need to refill them again and again for frequently even monthly in some cases. This will, in turn, hamper you financially with excessive cost, and again, nobody likes to refill brake fluids frequently as that is not as easy as refilling fuel. Besides, clean the brake fluid master cylinder at a regular interval to get better braking performance.

Hence, when it comes to the safety of you and your beloved automobile, it depends a lot on high performance liquid. Choosing the best brake oil may not nullify the chances of system failures, but it significantly reduces the chances of such unpleasant occurrences. Therefore, for the sake of your safety, choosing the top rated brake fluid is a must and something you should never ignore.

Conclusion

Brake oil may just be a simple product like many others, but it has a life-saving significance. When you're riding your vehicle, safety should always be your number one priority and so, ensuring that safety should be something you must always keep on the check. Upgrading to the best brake fluid dot 4 doesn't only enhance your brake response but also improves the overall efficiency of your vehicle. It makes your rides smoother and puts you more in control of the vehicle. Therefore, stay safe, choose the Best DOT 4 Brake Fluid.
