In all Toyota braking systems where DOT 3 brake fluid is advised, a special heavy-duty, high-temperature brake fluid was specifically created by Toyota experts to help deliver optimum performance.
For use in all Toyota motor vehicle braking systems, Toyota Genuine Brake Fluid is a premium, high-performance Dot 3 polyglycol brake fluid that has been specially designed for Toyota Motor Corporation.
High performance brake fluid is crucial for maintaining the best possible performance of braking systems. Hydraulic fluids like brake fluid enable the conversion of force into pressure. Brake fluid needs a high “boiling point” since it is exposed to high temperatures in order to prevent vaporization.

What type of brake fluid is used by Toyota?
In order to address a braking issue that arises after the vehicle has been serviced using genuine brake fluid and non-factory fill, Toyota Motor Sales has announced it will undertake a voluntary safety recall.
740,000 vehicles sold in the United States are affected by the recall, including the following models: 2005-2006 Avalon, 2004-2006 Highlander (non-hybrid), Lexus RX330, and 2006 Lexus GS300, IS250, and IS350.
The brake warning signal may illuminate as a result of a little amount of brake fluid leaking from the brake master cylinder. The driver will start to notice a spongy or soft brake pedal feel, and braking performance may gradually deteriorate, if the brake warning lamp has illuminated and the vehicle is driven without replacing the master cylinder brake fluid reservoir.
Non-factory Toyota brake fluid supplied during system maintenance was identified as the leak’s cause. According to Toyota, some replacement brake fluids are deficient in a specific polymer that prevents the internal rubber seal (also known as the brake master cylinder cup) at the piston’s tip from drying up and curling when the brake pedal is depressed.
According to the news release, “Polymers are present in the Toyota Genuine Brake Fluid utilized in car assembly for automobiles marketed in the United States. For some brake system parts, the polymers serve as lubricants.
A material that can function in an environment with lower quantities of this polymer was used to create the revised seal. No matter what type of brake fluid is used to maintain the system, this ought to stop any additional leaks.
Toyota recommends using DOT3 brake fluid that complies with SAE J1703 or FMVSS No.116 in its owner’s manuals and service instructions. These recommendations are still valid, and any brand of brake fluid is appropriate so long as it complies with DOT or SAE standards.
These standards emphasize compressibility and boiling point, but they also emphasize lubricating characteristics, seal compatibility, and corrosion resistance. However, each manufacturer of brake fluid has their unique set of additives. Usually, the unidentified polymer is a part.
First class mail will be used to contact the owners of the relevant vehicles starting in early November 2010. Dealerships for Toyota and Lexus will swap out the brake master cylinder cup for a brand-new model at no cost to the owners of the vehicles.

Toyota use synthetic brake fluid, right?
The braking fluid used in DOT 3, DOT 4, DOT 5, and DOT 5.1 is all synthetic. Glycol-ether-based DOT 3, DOT 4, and DOT 5.1 fluids are compatible with the original equipment Toyota fluid.
Is Toyota brake fluid required?
Toyota advises changing the brake fluid every 20,000 miles or two years, while there are a number of variables that can impact the recommendation. No two drivers are same, and some brake more forcefully than others. The age of your vehicle, how frequently you drive, and where you drive the most can all affect this.
Can Toyotas be used with DOT 4 brake fluid?
Any vehicle using DOT 4 brake fluid will have the same properties and boiling point. The DOT 4 fluid utilized in many automotive applications has no differences at all.
When should I replace the brake fluid in my Toyota?
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.
How important is the brake fluid’s brand?
Is it truly important? YES! It’s crucial to utilize the fluid that the original vehicle makers prescribed. Mineral-based fluid makes up DOT 3 & 4 brake fluid.
The finest brake fluid is…
The Motul Dot-4 100% Synthetic Racing Brake Fluid is our choice for the best brake fluid. It costs a little more than other manufacturers, but it gives the pedals a better feel, prevents water from getting inside, and boosts performance for both racers and daily drivers.
What about FVP brake fluid?
A great product that improves overall performance and aids in extending the lifespan of your brakes is FVP DOT3 Brake Fluid. Federal Standard 116 and SAE standards are met or exceeded.
Which brake fluid, synthetic or conventional, is preferable?
How long would synthetic fluid last in comparison to regular fluid? Because synthetic fluid can absorb more water before it reaches a crucial boiling point, it may be able to function for a little while longer.
Can old and fresh brake fluid be combined?
Both DOT 4 and DOT 5.1 braking fluids, which both contain glycol, are widely utilized in the automobile and cycling industries. The Department of Transportation (DOT) established the standards that are used to regulate them, hence the name.
The boiling points of these two brake fluids are the primary distinction. The minimum dry and wet boiling points are one of the requirements that DOT fluid producers must meet. These are the lowest temperatures that the brake fluid can operate at without beginning to boil, which can result in a complete failure of the brakes.
Let’s look at the Department of Transportation’s recommended minimum boiling temperatures for DOT brake fluid.
Remember that these are merely the basic requirements. It is feasible to find DOT 4 brake fluid with a higher boiling point than other DOT 5.1 fluids on the market, and brake fluid producers frequently do so.
Since DOT 4 and 5.1 are both glycol-based brake fluids, they can be mixed without damaging your brake system because they are compatible with one another. Never confuse DOT 5.1 (a glycol-based fluid) with DOT 5, a silicone-based fluid that must never be used with any other DOT fluid.
Which braking fluids can you actually combine without damaging your brake system, then? Let’s examine the graph below.
The silicone-based DOT 5 is the odd one out in this group and is incompatible with all other DOT brake fluids, as can be shown. The worst that can happen when mixing DOT 3, 4 and 5.1 braking fluids, providing it is new fluid, is a decrease in the boiling point of the entire fluid.
Some brake producers, including Hayes and Formula, ship their brakes with DOT 4 brake fluid already added. Some manufacturers, like Hope and Avid, decide to employ DOT 5.1 in their brakes. In order to take advantage of the higher boiling point and enhanced heat resistance of DOT 5.1, many riders with DOT 4 in their brakes will choose to bleed with it.
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.
What occurs if brake fluid is not changed?
The brake reservoir, where the brake fluid is housed, will become contaminated with moisture if you don’t change your brake fluid as advised by the vehicle’s manufacturer.
Your braking fluid will inevitably become polluted with “debris buildup” as it ages. Your brake system’s many seals and hoses might gradually lose little amounts of rubber as they wear down. Additionally, rust particles may get up in your brake fluid as a result of metal components corroding and rusting due to moisture-rich brake fluid.
Your car’s ability to stop suffers substantially from not changing the brake fluid, which results in subpar braking performance. Most of the time, you can tell by pressing the brake pedal: if it feels excessively spongy, your brake fluid is probably about to fail. You may find that stopping your car requires more work and time, and in some situations, you may even need to pump the brakes in order to build up enough pressure for a secure stop.
If you’re moving at any speed, the uncomfortable idea that your brakes could completely fail is also a deadly one. This may occur if the boiling point of the braking fluid is reached while the vehicle is in motion, particularly if the boiling point was intentionally decreased due to moisture contamination.
What happens if I combine brake fluids DOT 3 and DOT 4?
Yes, you can combine Dot 3 and Dot 4 brake fluid. Because both of these brake fluids are glycol-based, they are compatible with one another. It is not advised to fill your automobile with Dot 3 if it came with Dot 4 from the manufacturer, however the other way around is acceptable.
If your vehicle came equipped with Dot 3 and you frequently tow a trailer or drive up steep slopes, we strongly advise replacing it with Dot 4.
Can you mix Dot 5 with dot 3 and dot 4?
A silicone-based braking fluid is called Dot5. It is incompatible with ABS systems and does not absorb water from the atmosphere. It functions effectively and keeps its integrity. Additionally, compared to Dot3 and Dot4, it has a greater boiling point, making it more suitable for driving that is too aggressively.
It should never be combined with Dot3 or Dot4 liquids since they are incompatible. If you want to discover if your braking system is compatible with Dot5 brake fluid, you need also pay attention to the manufacturer’s instructions.
Better still, DOT 3 or DOT 4?
brake fluid DOT 4. The following are the main distinctions between the two: Over time, DOT 3 brake fluid will collect less water from the air than DOT 4, resulting in fewer frequent fluid changes. Due to its higher dry and wet boiling points, DOT 4 brake fluid is more heat-resistant.
Can DOT 3 and DOT 4 brake fluid be mixed?
Yes. DOT 3 and DOT 4 brake fluid are interchangeable. DOT 4 has a greater boiling point, though.
Due to its high boiling point, DOT 5.1 is utilized in high-performance and heavy-duty applications. The fluids DOT 3 and DOT 4 are compatible with it.
Because DOT 5 brake fluid is silicone, it does not absorb moisture. It is mostly utilized in vintage cars that are kept in storage for extended periods of time and require a brake fluid that doesn’t absorb water because it is incompatible with the other brake fluids.
