It’s critical that you keep an ample supply of brake fluid on hand. Here are the warning signs of low brake fluid and the cost of a brake fluid change.. If you’re looking for an expert on this subject, you’ve come to the right place. More information is available on the about page. In order to drive safely, one of your car’s most critical components is its brakes, as we constantly point out on Auto Chimps. Unfortunately, brakes are frequently overlooked by motorists. As far as they’re concerned, the brake pads and rotors are the most important parts. Brake fluid, on the other hand, is just as crucial. With out it, the car would not be able to safely slow down.

Brake fluid is critical, so let’s get started with that!

Why Is Brake Fluid Important?

Braking is a closed-loop system in your car. By this, we mean that nothing should be able to leave or enter the system. A hydraulic braking system means this is critical. A press on the brake pedal causes the brake fluid to be re-distributed, resulting in an increase in pressure and amplification of your foot’s pressure on the pedal. A clean, undamaged batch of brake fluid is required. Hygroscopic, on the other hand, describes brake fluid, which indicates that it draws water molecules from the air.

Slowly (unless there is a leak), but over time, this will result in a greater proportion of liquid.The braking fluid must be able to tolerate the heat in order to function effectively. Because water lowers the boiling point of braking fluid, it is less effective. It’s for this reason that changing the brake fluid on a regular basis is a good idea. The brake lines and other parts of the braking system are also protected by performing a brake fluid change.

When Should You Change The Brake Fluid?

This procedure must be followed when installing a new brake fluid. As a result, a brake fluid flush is often known as a brake fluid change. The recommended interval for changing the brake fluid varies from manufacturer to manufacturer. Every two years is a common recommendation, but in practice, it depends on the vehicle and the driver. Regular oil changes are a wonderful opportunity to double-check all of the vehicle’s fluids, including the brake fluid. Brake fluid should be replaced every three to five years for most vehicles, but you should always keep an eye on it.

If you look at the container, you can see how much brake fluid is left. It needs to be crystal clear or have a slight golden tinge to it. It should be replaced as soon as it darkens or becomes completely black.Check the brake fluid levels and color, but don’t leave the reservoir uncapped for too long, as this could taint the fluid and cause it to leak out.When it comes to changing the brake fluid, there’s no hard and fast rule. Your driving habits, the weather in your area and the make and model of your automobile all play a role in how much gas you use.

Signs And Symptoms Of Low Brake Fluid

You can tell when it’s time to change the brake fluid by looking at it, as was explained in the previous section. Even if you don’t see anything wrong with your brakes, you may want to check your brake fluid. It’s possible that a leak has occurred, despite the fact that routine maintenance should keep it from happening.The following are signs of contaminated brake fluid:

Activation of the ABS warning light

What happens when you step on the brake pedal?

decreasing braking force

Unpleasant odor

Braking problems should be corrected as soon as they arise. If you see any of these warning indicators, you should immediately stop your vehicle.

ABS Light Turns On

Your ABS light is likely to come on if your brake fluid is low since the system cannot function correctly if there is not enough fluid in the system. Even if your ABS light comes on for no apparent reason other than low brake fluid, keep this in mind.

Brake Pedal Behaves Differently

There are a number of things that could indicate a low or contaminated quantity of brake fluid by how the brake pedal feels when you press it. A spongy, bouncy, or loose feel while putting pressure to the pedal are all possible symptoms of this issue.

Loss Of Stopping Power

This is the most dangerous side effect that might result from a poor brake fluid. It’s possible that a problem with your brake fluid is causing your car to understeer when braking. A sudden onset of symptoms is possible, as is a gradual worsening. This issue must be dealt with as soon as possible, regardless of how it occurs.

Bad Smell

Even though an unpleasant scent is a seemingly innocuous symptom, it could be a sign of something more serious. Your brake fluid may also be the blame for the odor. Because contaminated brake fluid has a lower boiling point, it can begin to boil even after frequent use of the brakes is made. This frequently results in a strong chemical or burning odor.

How Much Does It Cost To Change Brake Fluid?

Brake fluid replacement is a time-consuming process, therefore most of the expense comes from labor. DOT 4 brake fluid is used by the majority of vehicles, while DOT 3 is used by a small number of vehicles. As a rule of thumb, your car’s manufacturer will tell you what kind of brake fluid to use. Fortunately, brake fluid isn’t a lot of money to buy. For 32 ounces of brake fluid, you should expect to pay around $5. You should only trust a skilled mechanic to perform brake fluid replacements. In most states, you may anticipate to pay between $80 and $130 for labor.

Bleeding Or Flushing The Brakes

Flushing and bleeding the brakes are two different things, yet many people use them interchangeably. Breathing in fresh air into your brakes is known as “bleeding the brakes.” Unless you plan on taking your car to the track, you won’t need this. The best course of action is to perform a brake fluid flush. New fluid will be used to replace all of your vehicle’s braking fluid, which is the greatest option from a maintenance standpoint.


When brake fluid begins to exhibit signs of deterioration, it should be replenished as soon as possible. Symptoms don’t always show when it’s time to replace brake fluid. The level and color of your brake fluid should be checked on a regular basis as a result. It’s best to perform a comprehensive fluid check at the same time as your vehicle’s oil change, if possible. Yellow-tinged brake fluid is ideal. It should be replaced as soon as possible if it is black or very dark. Although the brake fluid is kept in a sealed container, the water molecules in the surrounding environment will find their way into the fluid. Because of this, the fluid’s boiling point drops, and the brake system’s efficacy suffers as a result.


ABS light activation, odd pedal feel, unpleasant smell, and loss of braking power are all symptoms of fluid that is in poor condition. Changing the brake fluid is not a one-size-fits-all procedure. Changing it every two years is the recommendation of many manufacturers, but it is also contingent on a variety of circumstances, such as driving behavior and environment.DOT 4 and DOT 3 are the two most often utilized braking fluids in today’s vehicles. The more often used of the two is DOT 4.

You should only use the fluid that your car’s manufacturer has recommended for your specific model. Changing brake fluid can cost anywhere from $80 to $130 and is best left to a professional mechanic unless you are well-versed in the process and have the necessary tools. The process of flushing the brakes is not the same as bleeding the brakes. New brake fluid is pumped across the whole system during a brake fluid flush. The air bubbles in the brake system are the sole thing that are removed during brake bleeding, as opposed to brake fluid cleaning. In the end, you’ll have to replace the entire fluid supply. You should only flush your brakes when necessary, unless you drive your automobile on a track or otherwise do something unusual with it, like that.
