The brakes represent one of the essential parts of a car, and of course, this system is powered by a fluid that contains special properties, which allows correct braking at any time. Then, Can you mix dot 3 and dot 4?, simply, if it can, it does not represent any risk for the brakes, their parts and for driving. Know the importance of using an ideal brake fluid.

The answer is yes, mixing dot 3 and dot 4 brake fluid is safe. But, deciding on the fluid can represent a problem and I am wrong if it is not known. The brake fluid It is a vital part of the car’s braking system. It has the mission of working as a lubricant, which allows the brake pads not to drag on the rotors and generate wear. What it means, that brake fluid must be of high quality for the carso that it does not lose its properties and require replacement sooner than expected.

Some cars require extra care when mixing different fluids, It is all because they can present failures because they are not compatible and start generating a series of complications, such as mixing antifreeze with gasoline creates vapors that can explode and cause serious damage. Motor oils vary considerably between manufacturers and types of cars, depending on the use and compatibility requirements.

What is the difference between DOT 3 and DOT 4 brake fluid?

Generally, most automatic transmission fluids fall into one of two categories: DOT 3 or DOT 4. The difference between the two liquids is the freezing point.. A Fluid with a lower freezing point is designated as DOT 3, while a fluid with a higher freezing point is qualified as DOT 4..

DOT 4 brake fluid

DOT 4 brake fluids were designed to reduce the amount of parts used in the braking system. This Made from oil, it is used in all state-of-the-art vehicles and is compatible with ABS and silicone antifreeze systems.. The liquid also offers lower viscosity levelswhich means that has the ability to flow more easily and leaves no residue on piston surfaces when in contact with parts.

On the other hand, they contain several additives to the DOT 4 fluid, to allow the faster release of moisture in the system. Likewise, DOT 4 brake fluid will work with any wheel or tire combination and does not require corrosion inhibitors to be added to its composition.

DOT 3 brake fluid

This type of liquid contains a metallic baseso you have Suspended copper fragments, in order to help optimize the performance of the brakes, because it acts as a lubricant between the surfaces of the metallic pistons. Besides the liquid has hygroscopic properties (absorb and exhale moisture)so it traps moisture. This helps prevent the pads from friction welding when in contact with the brake discs. this liquid works well on aluminum, copper, steel and iron wheels, although they are not designed for use on cars that have ABS system.

They are often compatible with silicone antifreeze systems and are used in a variety of industries such as aircraft, automobiles, and other vehicles that require brake fluid. Also, DOT 3 is relatively inexpensive when compared to other types of fluids on the market.

What is the best brake fluid?

There are varieties of traditional brands on the market such as Castrol, Prestone, Bosch, among many others, who make some of the best brake system fluids. The brake fluid is a chemical mixture with various additive components, to ensure that the braking system works correctly. The liquids of common brakes are prepared based on special formulas to resist high temperaturesthe reason being that they do not become liquid sludge.

Fluids are regularly preserved, even after their manufacturers recommend changing the brake fluid. This brake fluid still has anti-corrosion chemicals that They are used to keep the metal parts of the braking system in good condition.. Common myths regarding brake fluids refer to applying a lot of pressure to the brakes, which can cause oxidation in the brake drums. It is a myth that has been unfounded, in addition to the mechanism behind the brake action, it is the difference in air pressure. Any rust will only show up if you applied enough pressure to boil the car’s brake fluid, it happens when you go down a hill too fast or hit the brakes hard.

Are DOT 3 and DOT 4 brake fluids compatible?

The answer is Yes, DOT 3 and DOT 4 brake fluids are compatibleand you will notice that the DOT 4 liquid, boils slightly higher than DOT 3. The compatibility is due to the fact that DOT fluids three and four do not contain solvents. Now the DOT three and DOT four brake fluids are synthetic and will not destroy the rubber seals in the master cylinder or brake pedal.


DOT 3 or DOT 4 brake fluids never oxidize, nor do they crack. However, this statement is not true, if DOT 4 brake fluid does not oxidize, while DOT 3 brake fluid does. fluids DOT 3 and DOT 4 are fully compatible, as long as they are used together. But, their boiling points differ, so it is advisable to replace the brake fluid when it has reached a year, which will offer maximum performance.

Can the brake fluid be filled?

In these modern times, most new brakes come in sealed systems, plus wear and tear from continual driving. Should you be sure yourself, fill brake fluid?, in case you have a modern car. The best thing is that the system Brake fluids are checked and filled by experts in the area. There may be a chance that some parts will need to be repaired or replaced due to wear or leaks within the system. The brake fluid has among its functions to regulate the pressure between the piston and the cylinder, so that it can stop or reduce the speed of the vehicle.
