Okay, let’s start by determining the brake fluid level. This process is simple. Lift the hood to see the reservoir for the braking fluid. On the left side of the engine bay, next to the firewall.
A close-up of the braking fluid reservoir is seen here. Observe the “Maximum fill line outside. The fluid should be filled up to this line. Additionally, a “On the reservoir, which is difficult to see in this image, there is a MIN link farther down.
As you can see, the brake fluid is positioned approximately 0.50 inches (1.25 cm) below the MAX line. Let’s go and add some liquid.
The rubber cover is easy to remove. Recall that you don’t want to expose the brake fluid to the air for any longer than is absolutely required. Why? due to the fact that brake fluid is hygroscopic, which means it can take up moisture from the air. The effectiveness of the braking fluid decreases as the water content rises. Additionally, for this reason, you must keep any unused brake fluid in a container that is tightly sealed.
All of this is to suggest that after you remove the cap, you should fill the container and put it back on fast.
Pour in some of the necessary brake fluid after removing the cap. The Sienna from 2003 to 2009 uses DOT 3 brake fluid. To find out if you require DOT 4, consult the owner’s manual for your car (many cars, including this one, specify the correct fluid on the cap of the reservoir as well).
Up till the MAX line is reached, keep adding liquid. then put the cap back on. Make careful to apply enough pressure so that it properly seals. That’s all, then!

How frequently should a Toyota Sienna have its brake fluid changed?
While no two drivers are alike and some may need their fluid to be replaced more or less frequently, Toyota advises changing your brake fluid every two years or 20,000 miles.
What occurs if the brake fluid level is low?
Does the brake pedal seem spongy, loose, or even bouncing when you press it? Does your car have to be stopped and slowed down by pressing the brake pedal all the way to the floor? You should change your brake fluid if this happens.
Air will enter the gaps in your brake line as a result of low brake fluid, resulting in soft brakes. When your brakes get spongy, it can be frightening and dangerous, especially if you don’t get them fixed right away.
Do you have any extra brake fluid?
You don’t need to add any brake fluid if it is at or above the “MIN line, indicating that the level is satisfactory. Add brake fluid until the level is just below the “MAX line if your fluid level is below the “MIN line. Then, carefully peel the reservoir top off. Avoid overfilling.
Should brake fluid be replaced every two years?
Let’s face it: you probably don’t think about your brake fluid all that often between taking care of your job, your house, and making arrangements with friends. To maintain the functionality of your brakes and your entire car, it is helpful to be aware of a few quick facts. Take this article as your “Brake Fluid 101.
YOU SHOULD REPLACE BRAKE FLUID EVERY FEW YEARS
You’ve probably heard that your engine’s oil is its lifeblood. In essence, it’s what fuels your motivation. However, brake fluid is as important to guaranteeing that you can stop. The easiest approach to determine how frequently to change brake fluid is to adhere to your manufacturer’s suggestions. According to certain manufacturers, brake fluid needs to be changed every two years. Others advise every three years or 45,000 kilometers. Some manufacturers offer almost no advice. Ask the skilled technicians at Jiffy Lube for advice if your vehicle’s owner manual makes no recommendations for how frequently to change brake fluid.
CONTAMINATED BRAKE FLUID CAN AFFECT HOW YOUR BRAKES OPERATE
Hydraulic brakes are used in all modern automobiles to slow down and stop. Furthermore, despite the fact that a hydraulic brake system is a sealed system, after years of regular usage, the brake fluidalso known as hydraulic fluidcan get polluted. This can happen when moisture gets into the hydraulic braking system and starts to influence the chemistry of the brake fluid, or it can happen when the additives in your brake fluid simply wear out over time. In any case, using brakes that are operating with tainted brake fluid can start to cause serious problems. For instance, you can observe soft brakes as you press the pedal or slower stopping distance when attempting a forceful stop. It’s time to bring your car to Jiffy Lube for a brake fluid check if you notice any of these symptoms.
REPLACING BRAKE FLUID IS COST-EFFECTIVE, PREVENTATIVE MAINTENANCE
Contaminated brake fluid and moisture in your fluid lines might harm your car more if you ignore them. This includes internal rust, corrosion, and rust on your brake calipers, brake lines, and other braking components, all of which can be expensive to fix. Fortunately, you may easily refill the brake fluid to probably prevent these problems. Moreover, the expense of replenishing brake fluid, often known as a “brake fluid flush,” is typically $100 or less. Additionally, Jiffy Lube’s professionals can advise using the brake fluid that your manufacturer prefers.
YOU CAN PERFORM YOUR OWN VISUAL CHECK NOW
It can also depend on how the fluid appears to determine how frequently brake fluid has to be changed. Additionally, checking the fluid yourself is not too difficult. Your car’s brake fluid reservoir should be opened. (It is often mounted to the top of the master cylinder under the hood.) Ideally, your brake fluid will be clear, but it could also have a faint orange, blue, or green tint. Bring the car in for service if the fluid appears dark or cloudy. Or, if you’re unsure of the brake fluid’s color, visit your neighborhood Jiffy Lube. A thorough brake fluid inspection can be done by the skilled specialists, including measurements of copper and moisture. We advise getting this test at least once annually, and if you live in an area with significant humidity, even more frequently.
The best advice of all? The brake fluid check is free when you visit Jiffy Lube for a Signature Service oil change. Jiffy Lube specialists are familiar with your type of vehicle’s brake fluid requirements and know what to check for. Additionally, since they are already working below your hood to change the oil, they can easily replace the brake fluid if necessary. The assurance that comes from knowing that you’re taking the greatest possible care of your car will give you the most peace of mind, though.

Why is the reservoir for my brake fluid empty?
“I assumed its high boiling point prevented it from boiling,” you said. It does, however it does so over a longer length of time than a typical sort of liquid. However, a high boiling point does not imply boiling-proof properties or a lack of boiling points. Over time, you might lose a few drops, and in newer cars, the braking fluid warning light will turn on when the level is too low.
However, you can check the reservoir, which is typically the white plastic container with the brake fluid label on the cap, as well as the DOT level if your car does not have brake fluid warning lights (the boiling point classification per the US Department of Transportation).
The concern is that due to a major issue, brake fluid level may drop low quickly. If you check the reservoir and find that it is almost empty, don’t be shocked. It most likely results from a leak in one of the braking lines, calipers, or master cylinders.
Examine any drops down the undercarriage in a corner of the vehicle’s rear to see if there are any leaks there. Additionally, look for any small or large splashes down the undersides of your car. Leaks can also be found in the calipers, master cylinder, and brake fluid reservoir in addition to the brake lines, therefore it is a good idea to perform a round-up inspection.
Use of power steering fluid in a 2017 Toyota Sienna?
According to our study, your car features an electronic power steering system (“EPS” or “EPAS”). These systems don’t have any power steering fluid to leak because they employ an electric motor rather than a hydraulic one. Typically, electric power steering systems are more fuel-efficient and require fewer maintenance.

Replace brake fluid
The first step in learning how to change brake fluid is to remove the old fluid from the reservoir and replace it with new fluid.
Some automakers advise changing brake fluid every 24,000 miles or every two years. Others fail to mention changing brake fluid at all. However, checking your brake fluid is simple. To check the color, simply dip a test strip into the fluid and match it to the chart on the container.
You can perform the fluid switch that comes close to a complete brake fluid cleanse, but not quite. You won’t completely replace the old fluid with new fluid during this treatment, but you will add enough new fluid to notice a difference.
