Your Guide to Buying a Brake Fluid

Whether you are the usual car owner who wants to keep his car running smoothly or a car shop owner who wants to keep a constant stock of high quality fluids for your clients, it is important that you choose only the best products for your well-loved vehicles.

If you are a car owner who wants to save money by minimizing the need for shop visits by maintaining a good running engine, it is imperative that you seek help from professionals or experts, especially if you do not have any experience in changing fluids.

Once it is established that your car needs a brake fluid change, then it is high time for you to go to the automobile shops or the department store to look for a brake fluid. But before making a purchase, take note of these factors first.

1. Price

Just like any product, one of the most important factor that you need to consider is price. As many would emphasize, you would not want to spend too much for buying a product that you do not even need.

Before buying brake fluid, you need to determine your budget first and also determine whether your car has a high performance engine like those seen in racing vehicles. We emphasize this since it is not practical if you want to place a high performance fluid, if you have an ageing sedan with a modest engine.

In addition, be careful with cheap brake fluids because most of these come with a catch. So before buying, you can ask your repair man regarding the brands that you should look out for or variants that are suitable for your car.​

2. Dry Boiling Point

​Dry boiling point is also one of the most important concerns when picking a brake fluid. Dry boiling point refers to the temperature at which a brake fluid boils out of the container considering that it is unspoiled by water.

A higher dry boiling point translates to lesser need for maintenance. With this, there is also a lesser need to change brake fluids. High performing brake fluids typically last for two years. While brake fluids with a low dry boiling point typically last only for a year of less. Therefore, frequent changing is required.​

3. Wet Boiling Point

While there is dry boiling point, there is also wet boiling point. Wet boiling point refers to the temperature at which the fluid boils after water has been taken into the fluid over time. This is important since the wet boiling point is one of the factors that keep the brake system cool and in tip top shape. Make sure that the fluid’s wet boiling point is enough to maintain a cool break system.​

4.​ Type of Brake Fluid

Different types of brake systems also need different types of brake fluids. It is important that you know what type of brake system you have before buying a new brake fluid. Make sure that the brake fluid you are buying is designed to work for your brake system.

There are several kinds of brake fluid. These include glycol-based fluids DOT 3, DOT 4 and DOT 5.1, as well as a silicone-based brake otherwise known as DOT 5.DOT stands for Department of Transportation and the differing categories are based on their boiling points.

The higher DOT number, the better is its quality and consequently result to a more expensive price tag. The manual your car comes with indicate what type of ABS system it has as well as the type of brake fluid it needs.​

How We Assessed and Evaluated These Products

For this article, we did an exhaustive research and testing of each product featured. In our pursuit to find the best brake fluid available in the online market of 2018, we have shortlisted a total of 30 products we think are the greatest both in term of price and value. But it would be nonsense if we discuss each one of them in this article as it would still not help you with your decision. So to help you decide, we have further narrowed it down to 5.

For our in depth testing, we have focused on the characteristics that set the best brake fluids from the other underperforming products. The characteristics we used to assess each of the products were based on: wet and dry boiling points, heat tolerance as well as DOT rating.

For wet and dry boiling point assessment, we determined the temperature at which they will boil. As mentioned previously a higher wet and dry boiling point will translate to better heat tolerance despite the amount of heat produced from the brake rotors and brake calipers.​

For DOT ratings, we have assessed them by the number at which they are categorized. This is usually seen on the back side of the packaging or by researching them online. A higher DOT rating results to better and more efficient performance and quality.

Lastly, to add a more rigorous manner of determining which one stood above the rest, we also dealt with evaluating their overall packaging and price.

We also did an in depth crowdsourcing of opinions from consumers as well as from our peers. This also gave us a bigger scope in terms of how we saw each and every product we feature. In this review article, we also sourced reviews from fellow reputable websites such as and

In this article, we made sure that all our views and opinions are all independent to provide you a more truthful and straightforward reviews of each product. Moreover, in each product we have highlighted their important features as well as gave our two cents regarding the things that they excelled at and areas that needed to be handled better or worked on more.

After several hours of exhaustive research and hands-on testing we have concluded which of the shortlisted products are the 5 best brake fluids available in 2018. Read on our product review to get a better picture of each product the next time you plan on changing fluids for your brake system.

Our Top Picks

1. Castrol 12614 Dot 4 Synthetic Brake Fluid - First Runner Up

The first entry on our list is the Castrol 12614 Dot 4 Synthetic Brake Fluid.

The Castrol 12614 is equipped with a unique formula engineered to provide better and a more smooth performance in today’s high temperature braking systems.

Most of the newly released and advanced cars need a brake fluid that will suffice to the high standard they need.

There is greater heat produced by the rotors by these new cars, that is why they need a brake fluid that has high tolerance to heat.

With the DOT 4 rating, you are assured that this product will provide optimal braking response, assuring you of better safety on the road despite high speeds or unforgiving roads.

When used with brake fluids with other DOT ratings or different kinds, the Castrol 12614 mixes well and will go hand in hand to provide a better response and smoother control with each brake.

We also noticed that the product excelled in reducing moisture in the ABS system, with this, you can expect that there is lesser possibility of corrosion in the components.
