Why should you use the best brake fluids?

Vehicle brake systems are built on the principle of hydraulics. It helps you to keep the car under your control. The main job of this method is to give you the power of stopping the vehicle. Some of you may think harder you press the brake pedal the better the brake system work. Well, I have to say it is just a misconception. Without brake fluid your car will lose the power of producing pressure to stop the vehicle. Now, going with a cheap quality brake fluid is not a right choice. You need to go with something which you can rely on upon without any tension.

You need to keep in check the brake fluid and change it when it is required. It is not car oil rather than a totally different thing.  Brake fuel is also known as hygroscopic fluid. You sealed brake can also absorb water. You should buy the best brake fluid which can give you water resistance. Also you need to make sure it is far from the moisture problem otherwise you may find some trouble with your car brake system. Always check the brake fluid reservoir and change it when it is needed. This will help you keep safe on the road and better performance.

Brake Fluid Dot 3 vs Dot 4 vs Dot 5

There is always a level which shows the margin how much brake fluid your car need. If you can see the level that means you need to add some more fluid with it. You should add something which has the ability to be with you even in the harsh condition. There are four different kinds of brake fluid on the market. They are mostly known as DOT 3, DOT 4, DOT 5 and DOT 5.1.  DOT 3 is meant for regular car and capture moisture at 2% rate yearly.

On the other hand, DOT 4 has better boiling point comparing to DOT 3. Both are poly glycol-based brake fluid, but DOT 4 is designed in a way so that it can accommodate big cars. Besides, DOT 5 is silicone-based brake fluid, and it does not absorb any type of moisture. It is forbidden to mix it with other brake fluid. DOT 5 is mainly engineered for race or rally car. DOT 5.1 is also meant for race car, but it will absorb moisture and made up of poly glycol.

Features of evaluating when purchasing brake fluid

There are several things to consider when buying brake fluid for your car. Such as dot layer, bottle size, oil base, abrasion resistance, lifetime, etc. This dot level indicates the estimate of your brake fluid lifting point. In addition, when you brake the car, the energy changes through those brake lines, which can lead to a rise in temperature. That dot layer will prevent this temperature to rise. Many times you can buy a large bottle at a lower price but check the quality of the fluid. Since not all types of fluids are made of the same material, be sure about the base of the fluid.

Basically, most fluids are made from synthetic, silicone, glycol, etc. So, make sure which of these is suitable for the brakes of your car. Generally, most fluids are able to provide rust protection to your car’s brakes so make sure the fluid is rust-resistant. You will be able to drive 20,000 miles through most of the brakes currently available on the market. In this case, you choose a fluid that allows the car to drive longer.



A: Generally, manufacturers decide what type of fluid to use in a vehicle. In most cases, the reservoir cap of the new vehicle is on the right, if this is not the case then take effective action from the manual of that vehicle. Remember, it is harmful to your car to use anything other than certain fluids.


A: To check your car’s brake fluid, first remove the cap from the plastic reservoir. If your car has a master cylinder made of metal, open the top with a screwdriver. Next, check how much fluid level your car’s brakes have. If the fluid level is less than half an inch, add new fluid.


A: Basically, the hygroscopic fluid reaches the foot through the brake pedal of your car. This gives you the ability to apply all the force to the brakes of your car so that you can forcefully hold those brake rotors.


A: If you don’t change the brake fluid at the right time, it reduces the efficiency of your car’s engine and absorbs water. As a result, your car’s brakes may be ineffective.


A: There is usually no time limit for changing the brake fluid of the car, change it depending on the type of car and the driving conditions. In most cases change it every four years or every five years.


A: There are some differences between DOT3 and DOT4. In general, dot3 has a higher risk of water absorption for the lower part of the temperature. In contrast, the water absorption capacity of DOT4 is somewhat lower.
