Brake fluid is one of the most important fluids in your car, as it helps you stop safely and smoothly. But how often do you need to change it? And what are the signs that your brake fluid needs to be replaced? In this blog post, we will answer these questions and give you some tips on how to maintain your brake fluid and your braking system.

What is Brake fluid and what does it do?

Brake fluid, also known as hydraulic fluid, is a liquid that transfers the pressure from your brake pedal to your brake calipers, which then squeeze the brake pads against the brake rotors to slow down or stop your car. Brake fluid also lubricates and protects the components of your braking system from corrosion and wear.

Brake fluid is usually clear or light amber in color when it is new, but it can become darker and more contaminated over time. This is because brake fluid is hygroscopic, which means it absorbs moisture from the air. Moisture can lower the boiling point of the brake fluid, which can cause it to vaporize under high temperatures and create air bubbles in the brake lines. Air bubbles can reduce the effectiveness of your brakes and make your pedal feel spongy or soft.

Moisture can also cause rust and corrosion in your brake lines, calipers, and other metal parts of your braking system. This can lead to leaks, damage, and reduced braking performance. Additionally, brake fluid can degrade due to exposure to heat, friction, and oxidation, which can reduce its viscosity and lubricating properties.

How often should you change your brake fluid?

The frequency of changing your brake fluid depends on several factors, such as your driving habits, your vehicle type, your climate, and your manufacturer’s recommendations. Some general guidelines are:

•  Check your owner’s manual for the specific interval for your car. Some manufacturers recommend changing the brake fluid every two years or 20,000 miles. Some cars have a maintenance reminder system that will alert you when it is time to change the brake fluid.

•  Check the color and condition of your brake fluid regularly. If it is dark brown or black, or if it has particles or debris in it, it is time to change it. You can use a brake fluid tester to measure the moisture content of your brake fluid and determine its quality.

•  Check the level of your brake fluid regularly. If it is low, it could indicate a leak in your braking system or excessive wear of your brake pads. You should top up your brake fluid with the same type and brand as the one already in your car. Do not mix different types or brands of brake fluids, as they may not be compatible and could cause damage to your braking system.

•  Change your brake fluid whenever you replace your brake pads or rotors, or when you service or flush your braking system. This will ensure that you have fresh and clean brake fluid in your car and that you remove any air bubbles or contaminants from your brake lines.

What are the benefits of changing your brake fluid?

Changing your brake fluid regularly can provide several benefits for your car and for yourself, such as:

•  Improving your braking performance and safety. Fresh and clean brake fluid can deliver optimal pressure and responsiveness to your brakes, allowing you to stop faster and more smoothly. It can also prevent vapor lock, which is a condition where the brake fluid boils and loses its ability to transmit pressure.

•  Extending the life of your braking system. Fresh and clean brake fluid can prevent rust, corrosion, leaks, and damage to your brake lines, calipers, master cylinder, and other components of your braking system. It can also reduce the wear and tear of your brake pads and rotors by providing adequate lubrication.

•  Saving you money and time. Changing your brake fluid regularly can help you avoid costly repairs or replacements of your braking system parts. It can also prevent breakdowns or accidents caused by faulty brakes.

Here are some tips for choosing and using brake fluid:

•  Choose the right type of brake fluid for your car. There are different types of brake fluids, such as DOT 3, DOT 4, DOT 5, and DOT 5.1, which have different boiling points, viscosity, and compatibility. Check your owner’s manual or consult with your mechanic to find out which type of brake fluid is suitable for your car.

•  Choose a reputable brand of brake fluid that meets or exceeds the specifications of your car. These brands offer high-quality brake fluids that provide excellent protection, performance, and durability for your braking system.

•  Store your brake fluid in a cool, dry, and dark place. Brake fluid can degrade due to exposure to heat, light, and moisture. Keep your brake fluid in its original sealed container until you need to use it. Do not use brake fluid that has been opened for more than a year, as it may have absorbed too much moisture and lost its effectiveness.

•  Dispose of your old brake fluid properly. Brake fluid is toxic and hazardous to the environment. Do not pour it down the drain or throw it in the trash. Take it to a recycling center or a hazardous waste facility that accepts used brake fluids.

Brake fluid is an essential fluid for your car that helps you stop safely and smoothly. It is important to change your brake fluid regularly according to your manufacturer’s recommendations or whenever you notice signs of deterioration or contamination. Changing your brake fluid can improve your braking performance and safety, extend the life of your braking system, and save you money and time. You can change your brake fluid yourself with some tools and skills, or you can take your car to a professional mechanic or a service center for a brake fluid change.
