What vehicles use DOT 4 brake fluid?

BRAKE FLUID DOT 4 is a state-of-the-art, high-performance, premium brake fluid of outstanding quality, with a high wet boiling point and thus extreme safety reserve against vapour lock. BRAKE FLUID DOT 4 is ideal for hydraulic disc brakes and drum brakes on motorcycles, cars, commercial vehicles and machines.

What happens if you use DOT 4 instead of dot 3?

DOT 4 brake fluid. The primary differences between the two include the following: DOT 3 brake fluid will absorb less water than DOT 4 from the air over time, meaning you'll need to have your fluid changed less frequently. DOT 4 brake fluid has higher dry and wet boiling points, making it safer for higher temperatures.

Can I use DOT 4 brake fluid in a DOT 3 car?

You can absolutely use DOT4 in place of DOT3 brake fluid.

The only thing you'll need to do is completely purge the system of the old DOT3 fluid to take advantage of the DOT4 features (higher boiling point both dry/wet). The only real difference between the two is how hot they can get before they boil.

Can I use any DOT 4 brake fluid in my car?

Yes, Dot 3 and Dot 4 brake fluid can be mixed. It's because both these are glycol-based brake fluids, which means that they are compatible with each other. If your car has Dot 4 from the factory, it's not recommended to fill it with Dot 3, though; but the other way is fine.

What happens if you use wrong brake fluid?

Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.

The Difference between DOT 3 and DOT 4 Brake Fluids

What is DOT 4 brake fluid used for?

BRAKE FLUID DOT 4 is a state-of-the-art, high-performance, premium brake fluid of outstanding quality, with a high wet boiling point and thus extreme safety reserve against vapour lock. BRAKE FLUID DOT 4 is ideal for hydraulic disc brakes and drum brakes on motorcycles, cars, commercial vehicles and machines.

What happens if you mix DOT 4 and DOT 5 brake fluid?

Can You Mix DOT 5 and DOT 4? No, DOT 4 is glycol-based, making it fundamentally incompatible with DOT 5 brake fluid. If your fluids do get mixed, you'll need to flush the entire system multiple times to remedy the situation.

What color is DOT 4 brake fluid?

The fluid can affect the paint of the vehicle, so you need to handle it with care. The color of the DOT 4 brake fluid is almost mineral clear with a little composition of yellow. It is compatible with DOT 3 and DOT 5.1.

What is DOT 5 used for?

DOT 5 is silicone-based brake fluid and is used in most new cars today. DOT 5 is expensive, but it has a dry boiling point of 356 degrees. Newer brake rotors tend to be smaller and thinner, which means they disperse heat a lot less efficiently. Also, DOT 5 does not absorb any moisture.

What does DOT 4 mean?

DOT 3 and DOT 4 brake fluids are glycol-based. They're used in most modern cars and trucks, because they work with ABS brakes. DOT 4 has a higher boiling point than DOT 3. You can use DOT 4 where DOT 3 is called for, but not the reverse. Using DOT 3 in a DOT 4 brake risks boiling the brake fluid.

Is all DOT 4 brake fluid synthetic?

DOT 3, 4, and 5 are all synthetic. DOT 3 and 4 are glycol-based products that differ only by their boiling points (DOT 4 is slightly higher). DOT 5 is silicone-based (also synthetic).

How do I know what type of brake fluid I need?

The best way identify what type of brake fluid your car needs is to check your owner's manual. You can also check the master cylinder reservoir cap to identify the type of brake fluid used in your vehicle.

How often should you change your brake fluid?

A good rule to follow is to have your mechanic check your brakes and brake fluid during every oil change. They'll be able to give you the best feedback on how your brakes are working and if they need new fluid. Most drivers find they need to change their brake fluid every four to five years.

What type of brake fluid does Toyota use?

Polyalkylene glycol based brake fluid designed to hydraulically transmit braking force from the brake pedal to the brake calipers/pads. Meets DOT 3, FMVSS (Federal Motor Vehicle Safety Standard) No. 116 and J1703 brake fluid specifications.

Why DOT 5 brake fluid is not recommended by any manufacturer?

To get a better handle on why we don't recommend DOT 5 for our brake kits, we need to take a crash course in chemistry. Common brake fluids such as DOT 3, 4, and 5.1 are mixtures of glycols and glycol ethers while DOT 5 is silicone based.

Which brake fluid is best?

Does brake fluid melt plastic?

Brake fluid won't melt the plastic, but it may make the plastic more brittle and easier to snap. However, brake fluid (not be confused with brake cleaner — which will ruin the plastic) also contains a highly toxic alcohol (diethylene glycol) that can kill you.

Does DOT 4 brake fluid absorb water?

DOT 3 and DOT 4 brake fluids are glycol-ether compounds--the most common stuff used for brake fluids. The major drawback to glycol brake fluids is that they are hygroscopic: they absorb water. When brake fluid gets wet, its boiling temperature goes down.

Are all DOT 4 brake fluids the same?

Since DOT 4 and 5.1 are both glycol-based brake fluids they are compatible with each other, which means they can be readily mixed without harming your brake system. It is important never to mistake DOT 5.1 (glycol-based) with DOT 5 which is silicone-based and should never be mixed with any other DOT fluid.

Is brake fluid same for all cars?

There are multiple different types of brake fluid that can be used for your vehicle. However, these are grouped into two headings: Glycol based - this includes brake fluids such as DOT3, DOT4 and Super DOT4. Silicone based - an example of a silicone-based brake fluid is DOT5.

Can you use any brake fluid any car?

Check your vehicle's owner's manual to see if there are any specific instructions for the type of brake fluid you should use. Also, the cap usually states what kind of brake fluid is required. For the vast majority of vehicles, a standard glycol-based DOT 3 or DOT 4 brake fluid should be used.

Does brake fluid need flushing?

Brakes are perhaps one of the most necessary elements of vehicle safety. However, many customers may find themselves wondering, “Is a brake fluid flush really necessary?” The short answer is yes. Your braking system relies on the hydraulic fluid to amplify your foot's pressure on the pedal.

How long can you keep DOT 4 brake fluid?

DOT Brake Fluid

Castrol recommends that DOT fluid in previously opened containers should be discarded after 12 months. In our opinion it would be unwise to use DOT fluid from a bottle which has been open for more than a few months, unless you have no other alternative.
