Do Teslas Use Brake Fluid? A Comprehensive Guide

The importance of brake fluid is something we all know, but when it comes to these newfangled electric cars, specifically Teslas, things can get a bit hazy. With Tesla taking over the auto scene, plenty are wondering: do those fancy electric machines use brake fluid? Well, let me tell you – we’re diving deep into this topic and getting the answers you’ve been craving.

Here’s the quick answer: Yes, Teslas use brake fluid for their braking systems. The brake fluid is a hydraulic fluid that helps to transfer pressure from the brake pedal to the calipers and ultimately stop the car. It is crucial to maintain the correct level of brake fluid in your Tesla for optimal braking performance and safety.

Do Teslas Use Brake Fluid? A Detailed Explanation

Being a Tesla fanatic, I get asked all sorts of queries about my ride, but one that’s often at the top of the list is whether my whip uses brake fluid. The long and short of it is yep – yet there are some nuances you should be privy to.

Now, before we delve into the nitty-gritty of fluids and whatnot, let’s first cover regenerative braking tech. To put it essentially, Teslas use this innovative feature to capture kinetic energy that arises while you’re braking your vehicle, which converts said energy into electrical juice thus being stashed away in the car’s battery pack. This baby hack is built for maximum efficiency- giving your break pads less wear and tear while banking some juicy energy reserves at the same time.

However, despite this advanced technology at work, Tesla still incorporates a traditional mechanical-based brake system for emergency situations. In these instances, the vehicle will engage a hydraulic system to operate the brakes using brake fluid.

So, what exactly is brake fluid? It’s a type of hydraulic fluid that transfers force from the pedal to the calipers or drums that press against your car’s rotors or wheels to create friction and slow down your vehicle. It’s vital for safe driving as it contributes to controlling your car during stopping or slowing down.

But why does Tesla use a backup hydraulic system when it already has regenerative braking technology installed? Well, regenerative braking isn’t always effective under all circumstances. Brake fluid gives another fail-safe option to drivers in case regenerative braking doesn’t function correctly or in an emergency situation.

What Fluids Do Tesla Cars Use?

Now you know that Teslas aren’t just run on electricity; they also have a backup mechanical braking system. This feature comes in handy when you need to brake abruptly, and there is no time for regenerative braking. DOT 3 brake fluid is an essential component of this system and ensures required hydraulic pressure for smooth operation of the brakes.

But that’s not all! Teslas require several other fluids to keep running smoothly. Coolant fluid plays an important role in maintaining the battery and powertrain cooling systems’ proper heat management while driving or charging. As we all know, overheating is never a good thing when it comes to batteries!

Tesla owners also need to make sure their windshield washer fluid levels are topped up regularly. The Tesla windshield washer fluid not only keenly cleans up both the windshield and GPS cameras at once but even includes bug removal! How handy is that?

Another crucial fluid present in Teslas is gear oil that helps keep your drive unit (front/rear) running smoothly without any friction or noise. Lastly, refrigerant solutions are used by climate control systems such as air conditioning. Maintaining refrigerant levels is crucial if you want to stay cool during hot summer days.

How Often Do You Need to Change Brake Fluid in a Tesla?

Brake fluid is a vital component of your Tesla’s braking system, and it plays a crucial role in keeping you and your passengers safe on the road. However, like any other liquid material, brake fluid can degrade over time under various environmental factors such as humidity or high heat scenarios even if not frequently used. 

As per recommendations from Tesla, all users should make sure that their brake fluid gets changed every two years. This recommendation is more flexible than most conventional cars that require a change around every 1-2 years or 24k-36k miles.

So why can Teslas go for longer periods before a brake fluid change is needed? Below are some of the reasons: 

  •  Teslas rely on regenerative brakes which use electric motors to slow down instead of hydraulic braking systems used in conventional cars. As such, the amount of brake fluid used compared to regular cars is significantly reduced. 
  • The electric motor in Teslas requires less mechanical use than traditional petrol engines in conventional cars. Because there is less wear and tear on the entire system, combined with regenerative braking technology, there is less stress and more efficiency in the braking system.

Delaying or overlooking recommended maintenance like changing your brake fluids could result in significant damage and costly repairs down the line. It’s not only about maintaining your vehicle; it’s also ensuring safety while driving.

How to Check and Change Brake Fluid in a Tesla?

Checking and changing brake fluid is simple yet essential maintenance that can significantly improve your vehicle’s lifespan in general. The good news is that checking brake fluid levels in Tesla isn’t much different from typical cars, and anyone can do it at home. 

Here are some tips on how to check and change brake fluid in your Tesla.

1. Locate The Master Cylinder Reservoir

The very first step in checking and changing the brake fluid in a Tesla is to locate the master cylinder reservoir. This crucial auto part is situated on top of the brake booster, which is often positioned near the firewall towards the back of your car’s engine bay.

2. Check Brake Fluid Levels

Once you have located the master cylinder reservoir, unscrew its cap and inspect where it registers inside of the cylinder body. A notched ring or side-notch will show you how much fluid remains in your system. If your brake fluid level gets too low, you may encounter longer stopping distances & weaker braking power. 

3. Change The Brake Fluid

If you identify that you need to change your Tesla’s brake fluid level (typically every two years), be prepared with proper DOT 3 qualified fluids ahead of time from trusted retailers/brands for such automotive requirements.

Tesla recommends using authorized service centers for this procedure; however, if you’re an experienced DIY car mechanic – there are resources available online via forums that can help guide you through this process safely—be mindful of taking precautions handling toxic fluids & wearing protective goggles/gloves while doing so.


In summary- yes; Teslas do use brake fluids just like other conventional vehicles but they tend to wear less frequently versus cars powered by fuels. However, this doesn’t mean forgoing important safety checks such as changing out brake fluids every 2 years. Additionally, electric vehicles require oil changes less frequently compared to petrol-driven engines since there are no fuel combustions taking place.

To optimize your Tesla braking system performance while extending life span,  proper cleaning of all vehicle’s parts for longevity, regular monthly checks on all accelerating/braking systems sensors are tips you may want to note.
