The disk type of most vehicles is filled with DOT 4 brake fluid - one of the most popular and widespread among analogues. The main differences between such agents are considered to be the boiling point, composition and ability to absorb moisture vapor. The DOT 4 category is considered the highest quality and most versatile. Compared to DOT 3, it absorbs several times less water and keeps the boiling point unchanged for a long time. Such features of the composition make it possible to extend its useful life.

Types of brake fluids

The DOT brake train systematization was formed by the US Department of Transportation. The FMVSS safety standards have been used as the basis for the creation of these standards. In translation, the abbreviation DOT stands for "Department of Transportation Security". The substances that bind moisture included in the composition are designated by the number 4. Such agents do not pass certification in accordance with GOST.

Since DOT 4 is not considered a petroleum product, it has a corresponding marking - a yellow octagonal figure bordered with a black line. In the center of the figure is a diagram of the brake system. A similar symbol, crossed out diagonally, indicates that such a composition cannot be poured into the system.

And the viscosity of dry and moisture-filled fluid are the criteria by which brake compositions are divided into types. Polyglycols are considered the base base of DOT 3 and DOT 4, but DOT 5 is based on silicone, which is why these categories do not mix with each other. The same substances are used to create liquids of the DOT 3 and DOT 4 categories, so they can be mixed and interchanged.

Marking and composition of DOT 4 brake fluids

Brake fluid DOT 4 contains linear polyethers and polyalkylene glycols in its base. In most cases, polyethylene glycol is used in the production of such compositions, however, it is often indicated on the packaging under a different name, since a variety of additives and liquid polymers are taken into account.

Unlike its predecessor DOT 3, DOT 4 liquid contains special additives - for example, borates. They bind water that gets into the material from the air during operation.

In sports cars, DOT 5.1 brake fluids are used, obtained by adding special additives and additives to the fluid of the DOT 4 standard.

Brake fluid compatibility DOT 4

For many motorists, one of the most pressing and burning issues is the compatibility of brake fluids of different classes and categories. Experts, as a rule, advise using formulations of well-known brands - such as Castrol brake fluid or Bosch brake fluid DOT 4. The composition labeling must be observed.

A huge number of different brake fluids are presented on the Russian automotive market. It is not advised to mix them with each other, however, in emergency cases this can be done, but it is advisable to be guided by certain rules.

Can be mixed with analogs such as DOT 3, DOT 4.5, DOT 5.1. It must not be diluted with silicone-based agents such as DOT 5 and DOT 5.1 (ABS).

Brake fluid DOT 4 - characteristics

The main physicochemical parameters of the compositions that affect their quality are:

• viscosity;
• boiling temperature;
• the ability to absorb moisture vapor;
• corrosion resistance.

According to the requirements for the DOT 4 standard for liquids, their boiling point should not be lower than 250 ° C. This indicator can be reduced to 165 ° C for those liquids that absorb moisture from the environment in a total amount of up to 3.5%.

The viscosity of a liquid is measured with a viscometer. This parameter should not exceed 750 mm 2 / s. In practice, one of the main properties is only viscosity, while the density of the brake fluid is practically not taken into account anywhere.

Corrosion resistance of DOT 4 fluid is directly related to its acidity level. A normal value is in the range of pH 7.0-11.5 units.

Service life of brake fluid

Depending on the additives and additives, hygroscopicity and operating conditions, the life of the agent may vary. For example, low-quality parts in the brake system can alter the characteristics of the brake fluid, which affects its function and service life. For this reason, the brake fluid is changed every 2-2.5 years.

Why DOT 4?

Brake fluid DOT 4 has the following advantages, thanks to which it is one of the most popular in the world:

• reliability;
• affordable prices;
• wide range of temperatures at which it can be used.

Expensive DOT 5.1 is practically not used by motorists, since it is more expensive, but its functionality is no different from DOT 4. Tests carried out by experts and amateurs show that DOT 4 brake fluid is the gold standard. Reviews left on the composition confirm its reliability and high quality, coupled with an acceptable cost.

Boiling temperature

The kinetic energy of the vehicle is converted into heat during braking. The pads, when heated, transfer it to the pistons and the caliper body, which is already heated by the brake fluid. Based on this, the first requirement is put forward for it: a high boiling point, which will avoid the "failure" of the brake pedal. The high speed mode of modern cars has led to the fact that the old types of such formulations ceased to cope with their functions, and they were replaced by DOT 4 brake fluid. Toyota, one of the most reputable automobile concerns in the world, advises using just such formulations.

Corrosion resistant

The second requirement is minimal corrosiveness. Oxidation of the metal of the pistons is not the worst thing that can happen, much more dangerous is the corrosion of the brake lines. It became possible to ensure a high boiling point of the brake fluid only through the use of a polyethylene glycol base, which has a high level of hygroscopicity. Because of this, DOT 4 formulations are only stored in tightly closed containers. A fluid that has accumulated a large amount of water not only accelerates corrosion processes in the brake system, but also boils at a much lower temperature. This is common with motorcycles and sports cars: brake failures during aggressive and fast driving can cause serious accidents.

Lubricating properties

Good lubricating properties are the third requirement for brake fluids. These characteristics help to reduce wear on both the ABS valve body and the brake cylinder cuffs. The standard DOT 4 in these parameters is somewhat inferior to the new DOT 5, while the latter has a higher boiling point and a lower level of hygroscopicity, which makes it possible to use it for fast driving. DOT 5.1 fluids were developed for vehicles equipped with a small amount of glycol base. For most vehicles, it is desirable to use fluids of this particular class, since they are compatible with seals that are designed for previous fluid standards.

High viscosity

A high level of viscosity is the fourth requirement for brake fluids. The retention of the viscosity of the fluid allows the braking system to function normally at any ambient temperature. This parameter is most important for vehicles with an ABS system. After the solidification of the liquid can cause the valve body to fail on those cars on which the exchange rate stabilization is tied to the anti-lock braking system. This also includes modern crossovers: failures in the traction distribution system will cause poor vehicle handling.

Mobil brake fluid

Brake DOT 4 is used in accordance with the following recommendations:

• It is poured only in concentrated form from a new package or tightly closed.
• Immediately after use, the bottle should be tightly closed, since the composition quickly absorbs moisture from the environment, which negatively affects its operational life.
• Drained brake fluid cannot be reused.
• Spilled compound is removed immediately, as it can corrode the body paintwork.
• The term for replacing the brake fluid is once every two years or every 40 thousand kilometers.
• Fully compliant with DOT 4 standards and can be applied to ABS systems.
• Can be mixed with DOT 4 and DOT 3 brake fluids.

Brake fluid "Castrol"

Despite the fact that the brake DOT 4 is certified according to the DOT 4 standard, its boiling point exceeds the requirements and is 265 ° C, if water gets in it - 175 ° C. According to the manufacturer's recommendations, it needs to be changed every two years, respectively, it can be poured into sports cars.

Brake fluid "Castrol" DOT 4 is sold in a very inconvenient packaging: it is impossible to find a 1 liter bottle in car stores. For this reason, when replacing a liquid, you will have to buy several half-liter containers, overpaying for packaging. This is noted by many car owners.

The advantages of this brake fluid:

• Resistant to boiling even when moisture gets into the composition.
• Compliance with more stringent standards.
• Ideal for vehicles with ABS - has good viscosity properties.

Brake fluid "Rosa"

Brake fluid "Rosa" DOT 4 is a mixture containing anti-corrosion and antioxidant additives and boron-containing polyester. Differs in good boiling points in dry and wet form - 260 o C and 165 o C, respectively. It can be operated at ambient temperatures ranging from -40 o C to +45 o C.

Brake fluid "Rosa" DOT 4 is used in brake systems of passenger cars and trucks, including domestic front-wheel drive vehicles.

The service life of the fluid is three years. It can be mixed with such compositions as "Neva" and "Tom" without loss of characteristics.

Sintec brake fluid

Perhaps one of the most affordable (only 100 r) brake fluids of domestic production. The brake fluid "Super" DOT 4 is produced at the "Obninskorgsintez" plant. Despite domestic production, in terms of its characteristics, it can overtake many imported counterparts: the boiling point is 240 ° C in dry form and 155 ° C in wet form. Ideal for measured rides, slight differences in viscosity are not felt while riding.

The only drawback is the unstable characteristics: all the tests that the brake fluid from Obninsk passed showed different results. Of course, this does not affect the requirements of the standard, however, it does not say anything good about the manufacturer.

Liqui Moly brake fluid

Liqui Moly brake fluid in its characteristics loses to its counterparts: the boiling point for the dry and wet version is 230 ° C and 155 ° C, respectively, at low temperatures the viscosity is 1800 mm 2 / s. The characteristics of the composition ideally correspond to the standards of DOT 4, but do not exceed them. Affordable price 300 r. to a certain extent this compensates, however, it is definitely not worth using such a liquid in our climate for cars with ABS.

Separately, it is worth noting the excellent lubricating and anti-corrosion properties of Liqui Moly, which the manufacturer emphasized. By its properties, this brake fluid is ideal for drivers who prefer a calm driving rhythm and who live in the middle lane of our country.

Benefits of Liqui Moly brake fluid:

1. Excellent anti-corrosion properties.
2. Protects brake hoses and rubber seals.

Brake fluid selection

The correct brake fluid is selected according to the vehicle specifications. You can find out exactly which composition was filled at the plant, and which one can be used in the future, in the manual for the repair and operation of the car. You can also ask an authorized dealer.

It is worth paying attention to such parameters of brake fluid as boiling point in dry and wet form, viscosity and standard. Categories below DOT 4 cannot be used for cars equipped with an anti-lock braking system, since this can lead to damage to both the ABS itself and the brake system.

You can go to a service station from an authorized dealer to diagnose the system and fill with new brake fluid.

If you are confused in the choice and in the designation of brake fluids, then this article is for you. You will learn about the differences between the DOT standard in temperature conditions and additives used in production. Using the Land Cruiser and LC Prado as an example, we will tell you which fluid is suitable and what are the advantages of using this or that product.

The ABS system requires a certain approach and it is important to know what to choose if you are going to change or add "brakes" to the reservoir. And there are also specials. liquids that can withstand overloads up to huge freezing temperatures, and are relevant for racing cars or bikes.

Each product is tailored to meet specific requirements. And now more about each drug.

Dot 4 characteristics for brakes

Probably the most versatile fluid that does not require special operating conditions. It is a kind of departure point for most modern cars. Of the advantages, one can single out a rather high prevalence, good high-temperature characteristics.

At low temperatures, it thickens strongly, which inevitably leads to a decrease in the range of application of the liquid. This means that it is a high-viscosity brake fluid that meets the requirements of most braking systems.

Dot 4 for ABS choice

But every year cars are improving and therefore the task of creating a new generation drug that meets the needs of a modern car has arisen. A drug was created especially for the most modern cars with not only ABS systems, but also stabilization and anti-slip systems.

The peculiarities of such systems is that they are able to control the behavior of the car on the road, changing the configuration of the braking system, it is even able to recognize what type of surface you have under the wheels: soil, sand, asphalt, ice or water.

The result is full-fledged intelligent systems. Therefore, for such systems, very fast action is needed in order to instantly transmit the signal from the cylinder block to the wheelset through sufficiently long channels of the brake system.

To ensure such performance, you can use one option - to increase the diameter of the tubes, but as a result, we will get the vulnerability of the channels to the environment and, moreover, it will be very difficult to hide them in the system. Such systems are especially bad for winter operation. Therefore, to ensure good handling, you need to provide a good response. And as an option at low temperatures, you need to use a low-viscosity liquid.

SL6, unlike Dot 4 "normal", has a low-temperature viscosity. Today it is the newest fluid that meets the modern requirements of cars.

Dot 5.1 advantages and differences from SL 6 Dot 4

Dot 5.1 Closely competing liquid with the newest SL6. The main role here is played by one after 5. There is the usual Dot 5 standard, which is not widely available.

Dot 5 is a silicone lubricant used in sports equipment and also on motorcycles. It can also sometimes be found in some military equipment. After some time, the representatives thought that it was necessary to replace this rather unsuccessful drug with a more common one.

Therefore, as a sequel to Dot 4 SL 6 appeared. The low-temperature viscosity was reduced, but not like the modern SL6, but it was still reduced.

Second point: high temperature properties have been enhanced. Dot 5.1 has the highest wet boiling point. Therefore, it has its own niche of application.

Brake fluid for racing cars and superbikes

A little apart is the sports brake fluid -.

The peculiarity of this drug is that it has a dry boiling point of about 300 degrees Celsius. The liquid is sharpened for work in high temperature conditions.In a conventional system, at these temperatures, there will be a problem with the seals.

The tool is in demand by motorcycles, since the temperature of the parts of the brake system is always high, due to the high heat transfer to the brake cylinders and brake discs.

It also goes to forced car engines or cars brought to these conditions, for example, "tuned" ones. But please note that the low temperature viscosity is equal to the Dot 4 standard.

Brake Fluid Comparison Chart

Now let's try to attribute these liquids to some features. The first two fluids, Dot 4 and the Race version of Dot 4, are full viscosity oils. They thicken enough at low temperatures and can withstand temperatures up to 230-320 degrees. First of all, you need to remember that these oils are either for motorcycles, or for racing and "semi-race" cars. Both types of equipment are rarely used for winter operation and are not in demand in our country. For normal operating conditions with thinking systems, both liquids: Dot 4 SL6 and Dot 5.1 do not differ in any way in terms of dry boiling point. The products are low-viscosity and therefore work perfectly at high temperatures. If we talk about companies, then it is more in demand in the Asian market of automakers.

Brake fluid for Toyota Land Cruiser and Prado

For example, for modern Toyota cars - Land Cruiser and Prado - it is recommended to use Dot 5.1, since the cars are equipped with intelligent ABS systems.

For example, a Land Cruiser on a gravel or sand surface slows down much faster than a conventional car with an ABS system.

Such a system itself recognizes the percentage of slipping of the system and will try by all means to reduce it, thereby reducing the braking distance, but such cars have strict viscosity requirements, in principle, like all SUVs, which are heavily overloaded when driving on asphalt.

Someone can force rivers, someone swamps and therefore the risk of moisture entering the system increases. This is another argument for using Dot 5.1.

By the way, the very use of this fluid was initially committed to SUVs, but over time, Dot 5.1 took root in more road versions.

Dot 4 SL6 is a more European variant. Are aimed at more civilian use and the requirements for these fluids should be guided by the ingress of moisture into the system, as road cars move at higher speeds.

In contrast to Dot 4, better low-temperature viscosities have been put forward and drier requirements for dry boiling point, slightly at the expense of wet boiling point. Therefore, this is such a block of brake fluid.

Results of comparison of characteristics of Dot 4, 5.1, SL 6, Racing Fluid

As a result, Dot 4 is a more versatile grease for normal operating conditions.

Dot 5.1 fluid for modern braking systems with ABS.

Dot 4 SL6 is more European orientation; and "Racing Break" Dot 4 targets higher performance cars and motorcycles.

And besides, it is well involved in the motorcycle segment. But the lower viscosity limit for this fluid is essentially not used, due to the fact that no one will use a motorcycle at low temperatures.

Brake fluid provides efficient operation of one of the most important systems in a vehicle, so the importance of its performance should not be underestimated. The resistance of Dot-4 to oxidation processes, hydrolysis, as well as a high boiling point and lubricating properties directly affect the reliability of the brake circuits and the durability of the cylinders and lines of the system.

The review presents the best brake fluids on the domestic market. The rating was compiled on the basis of the declared characteristics, as well as the opinions of auto service specialists. Feedback from users with a preference for one of the participating brands was also taken into account.

Owners who have once experienced the properties of this product prefer to use this brake fluid the next time they change. The lubricity of the liquid, the absence of the influence of low temperatures on the response efficiency and the extended drain interval, which does not affect safety at all, are highly appreciated.

What indicators of brake fluid is affected by moisture

There are several indicators that characterize the ability of a brake fluid to be affected by moisture.

1. When braking, the temperature in the closed circuit of the hydraulic drive rises. A high water content leads to the appearance of dips, similar to the airing of the system.
2. For smooth operation of the brakes and the ABS unit, the product must have good lubricating properties. In this regard, fluids of the new DOT 5 standard prove themselves best.
3. In severe frost, the brakes must remain fluid, this is especially important for cars with ABS. This depends mainly on the stability of an indicator such as viscosity. Moisture ingress unambiguously worsens this parameter.
4. When it comes to corrosion resistance, manufacturers spend a lot of time and money inventing additives that prevent rusting of parts inside the hydraulic drive. It is very dangerous when, during emergency braking, a cylinder gets stuck in the caliper or the tightness of a metal tube is broken.
