What is Brake Fluid?

Brake fluid is an essential component of a hydraulic braking system in modern cars. Its primary function is to transmit force and pressure from the brake pedal to the brake calipers. The force then activates the brake pads, stopping the wheels from turning. 

This fluid works by exerting pressure on the brake cylinders, which then transfer this pressure to the brake pads. As a result, the brake pads press against the rotor, causing friction and stopping the car.

Brake fluid is typically made of glycol-ether, which is a type of alcohol that is known for its high boiling point and excellent lubricating properties. In addition, brake fluid contains several additives that help to enhance its performance, such as rust inhibitors, anti-foaming agents, and anti-corrosion agents.

Why Brake Fluid Must be Changed Regularly?


The brake fluid in your car’s braking system needs to be changed regularly because it can degrade over time due to exposure to heat, moisture, and air. When the brake fluid becomes contaminated or breaks down, it can cause several problems with your car’s braking system. It can lead to reduced brake performance, sponginess, and even complete brake failure. Therefore, you must avail of regular car brake service to keep your car running safely.

Here are some of the reasons why brake fluid needs to be changed regularly:

Water Contamination 

Brake fluid is hygroscopic, which means it attracts moisture from the air. Over time, this moisture can accumulate in the brake lines and cause the brake fluid to become contaminated. 

As water contamination increases, the boiling point of the brake fluid decreases, making it more likely to boil and create a vapor lock. When this happens, the brakes become spongy, and stopping distances increase. 

Regularly changing the brake fluid can help prevent water contamination and maintain proper brake performance.

High Temperature 

The braking system generates high temperatures, especially during hard braking or driving in mountainous areas. As brake fluid absorbs heat from the brakes, it can reach its boiling point and start to vaporize. 

This vaporization can cause air bubbles to form in the brake lines, leading to a loss of pressure and reduced braking power. Changing the brake fluid during regular car brake service helps to maintain its high boiling point and prevent vapor lock.


Brake fluid is a corrosive substance, and over time, it can cause rust and other forms of corrosion in the brake lines, calipers, and other brake components. 

Regularly changing the brake fluid can help prevent corrosion and extend the lifespan of your braking system.

Brake System Maintenance 

Regularly changing the brake fluid can help you identify and address potential problems with your braking system. During a brake fluid change, a technician can inspect the brake lines, calipers, and other components for signs of wear or damage, and recommend repairs or replacements as needed.

The frequency with which you should change your brake fluid can vary depending on your driving habits, the make and model of your car, and other factors. Most manufacturers recommend changing the brake fluid every two years or 24,000 miles, whichever comes first. 

However, if you frequently drive in stop-and-go traffic, in mountainous areas, or tow heavy loads, you may need to change your brake fluid more frequently.

It is always advisable to consult your car’s owner’s manual or a qualified technician to determine the recommended service interval for your car’s brake fluid.

Ignoring the recommended car brake service interval for your car’s brake fluid can lead to several issues, including:

  1. Reduced Brake Performance

    Over time, the brake fluid can become contaminated or break down, leading to reduced brake performance. This issue can manifest as sponginess in the brake pedal, longer stopping distances and a general decrease in braking power.

  2. Complete Brake Failure

    If the brake fluid becomes too contaminated or degraded, it can cause complete brake failure, which can be extremely dangerous. A brake failure can result in an accident, injury, or even death.

  3. Costly Repairs

    Neglecting to change your brake fluid regularly can lead to corrosion, which can damage other components of your braking system. Repairing or replacing these damaged parts can be expensive.
