Everything You Need To Know About Brake Fluid…

Brake fluid is a type of hydraulic fluid used in your brake systems. Its main purpose is to transfer force from the brake pedal to the brakes themselves. A fluid is used because fluids are incompressible. It transmits all the energy from your foot to the brake pistons.

Without your brake fluid, you wouldn’t be able to stop your vehicle.

When you press the brake pedal, the brake fluid is forced through a set of hoses and into the calipers, where it activates the pistons that push the brake pads against the rotors, slowing down or stopping the wheels.

Brake fluid is designed to withstand high temperatures and pressures, but over time it can become contaminated with moisture or air, which can reduce its effectiveness.

In this article, we’ll tell you everything you need to know about your car brake fluid!

Is It Really Necessary To Change Brake Fluid?

Brake fluid is hygroscopic, meaning it absorbs water from the air. This can cause corrosion and other problems in the brake system. Additionally, old brake fluid can start to break down, making it less effective at doing its job. For this reason, it’s important to change your brake fluid on a regular basis. Especially for your safety, it is very important to maintain your brake and make sure they perform at their best!

Most manufacturers recommend changing it every two years or so. However, if you live in a particularly wet or dirty environment, you may need to change it more often.

So whether you’re due for a change or not, it’s always a good idea to check your owner’s manual to see what the manufacturer recommends.

How Often To Change Brake Fluid?

As you might imagine, it depends on a few factors. If you do a lot of driving in stop-and-go traffic, your brake fluid is going to get dirtier faster than someone who mostly drives on the highway.

In general, though, most carmakers recommend changing your brake fluid about every two years or so. You can check your owner’s manual for specific recommendations. Some automakers have started using synthetic brake fluids that are supposed to last longer, so you might be able to go even longer between changes if you have one of those. Of course, it’s always a good idea to keep an eye on your fluid level and give it a visual inspection every now and then to make sure there isn’t any moisture in there that could cause corrosion.

How Much Does It Cost To Replace Your Brake Fluid?

The cost of replacing your brake fluid will depend on the type of vehicle you have and the size of your brake system. Generally, you can expect to pay between $100 and $250 for the service. However, if you have a larger vehicle or a more complex brake system, the cost may be higher. Be sure to check with your mechanic before scheduling the service to get an accurate estimate of the cost.

Can You Mix Old And New Brake Fluid?

When it comes to your car, it’s important to make sure you’re using the right fluids. Brake fluid is no exception. Though you might be tempted to top off your brake fluid with whatever you have on hand, it’s important to know that not all brake fluids are created equal. So, can you mix old and new brake fluid? The short answer is no. 

When it comes to brake fluid, there are two types that are commonly used: DOT 3 and DOT 4. DOT 3 is the older type of brake fluid, while DOT 4 is the newer type. Brake fluid has a shelf life, and DOT 3 brake fluid typically lasts about two years before it needs to be replaced. DOT 4 brake fluid, on the other hand, can last up to four years.

In general, it is not recommended to mix old and new brake fluid. The reason for this is that brake fluids have different properties, and mixing them can result in decreased performance. For example, DOT 3 brake fluid is more hygroscopic than DOT 4 fluid, meaning that it absorbs moisture more easily. This can lead to corrosion and reduced braking performance over time. Additionally, mixing the two types of fluids can cause compatibility issues, as they are not necessarily compatible with each other. As a result, it is generally best to use the same type of brake fluid throughout your vehicle’s lifetime.

Conclusion

Maintaining your brake fluid is important for the safety of you and your passengers. In general, carmakers recommend changing your brake fluid about every two years or so. However, if you live in a particularly wet or dirty environment, you may need to change it more often. You can check your owner’s manual for specific recommendations. Of course, it’s always a good idea to keep an eye on your fluid level and give it a visual inspection every now and then to make sure there isn’t any moisture in there that could cause corrosion.
