What is the difference between DOT 4 and DOT 4 Plus?

What is the difference between DOT 4 and DOT 4 Plus?

Regular DOT 4 has a minimum Wet Boiling Point of 165 degrees Celsius, while the DOT 4+ spec is 180 degrees. according to this website. While you could use water in your system (until it boiled) to stop your car, I wouldn’t recommend it. Could you use DOT4?

What does the DOT number mean on brake fluid?

The DOT ratings for brake fluid represent their boiling points when dry or wet. Brake fluid contains glycol which attracts water. Over time it is normal for brake fluid to absorb a certain level of moisture, so brake fluid ratings include a “wet” boiling point number along with a “dry” boiling point number.

What is brake fluid Dot 4 plus?

DOT 4 Plus Brake Fluid. Brake fluid is an important component within a vehicle’s braking system. febi DOT 4 Plus is a fully synthetic brake fluid based on glycols. It contains oxidation and corrosion inhibitors, has excellent dry and wet boiling point properties, and also prevents the formation of vapor bubbles.

What brake fluid does Toyota use?

DOT 3 brake fluid
Used to help provide superior performance in all Toyota brake systems where DOT 3 brake fluid is recommended, this is a super heavy-duty, high-temperature brake fluid designed by Toyota engineers.

Can I mix DOT 4 and DOT 4+?

1 are all Glycol based. The differences are in viscosity and boiling point. Use the grade that your car calls for (Volvos are usually DOT4), with DOT4 and DOT4+ pretty much interchangeable. DOT5 is silicone based.

Can I mix DOT 4 and DOT 4 Plus?

You can mix any of them except for DOT5. Even DOT5. 1 is OK since this also a glycol based fluid. If you mix DOT3 and DOT4 fluids (or different brands) you may get unpredictable boiling performance but otherwise it should not be a problem.

What does DOT 4 stand for?

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.

What color is DOT 4 brake fluid?

New glycol-based fluid (DOT 3, DOT 4, DOT 5.1) is a translucent yellow color. In fact, it almost looks clear when you pour it out of the bottle. Fresh DOT 5 brake fluid is a purple color. This allows you to easily distinguish between glycol- based and silicone-based brake fluid.

Can you mix DOT 4 and DOT 4+?

The differences are in viscosity and boiling point. Use the grade that your car calls for (Volvos are usually DOT4), with DOT4 and DOT4+ pretty much interchangeable.

What color is DOT 4 plus 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 type of brake fluid does a Toyota Rav 4 take?

Officially, Toyota recommends the use of Toyota genuine OEM brake fluid 00475-1BF03, but You can get away with any DOT 3 or DOT 4 fluid from a reputable brand. Just remember that You typically get what You pay for, so going with a “budget” fluid brand may cause You more headache in the long term.

Does Toyota use special brake fluid?

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.

What does FMVSS 116 mean?

For example, FMVSS No. 116 specifies the use of materials and apparatus set forth in the tables and appendices of SAE Standard J1703 to conduct brake fluid testing.

What is the corrosion test in FMVSS 116?

The corrosion test in FMVSS No. 116 (S5.1.6 and S6.6) evaluates the corrosive effects of brake fluid on several Start Printed Page 5554 materials that are designed to come into contact with brake fluid, including iron, steel, aluminum, brass, copper, and SBR.

What is § 116 of the Texas standard for brake fluids?

§ 571.116 Standard No. 116; Motor vehicle brake fluids. S1. Scope. This standard specifies requirements for fluids for use in hydraulic brake systems of motor vehicles, containers for these fluids, and labeling of the containers.

How do you test for stratification in FMVSS 116?

Place tube and test fluid from S6.10.3 (a) of FMVSS No. 116 for 24 ± 2 hours in an oven maintained at 60 degrees Celsius ± 2 degrees Celsius (140 degrees Fahrenheit ± 3.6 degrees Fahrenheit). Remove the tube and immediately examine the contents for evidence of stratification.
