Automotive Glossary

●ABS/Anti-lock Braking System

When you step on the brakes, the tires rub against the road surface and the car stops, but if the road surface is wet with snow or rain, the friction between the tires and the road surface becomes weaker, making it difficult for the car to stop even if you step on the brakes.

It is a system that momentarily releases the brakes just before the friction weakens so that the car will stop well even if the road surface is wet, and always maximizes the friction between the tires and the road surface.

Actually, rather than improving the friction between the tires and the road surface, the steering wheel works while applying the brakes and the effect of avoiding danger is greater. ABS is installed in 98.9% of vehicles sold in 2019.

●EBD/Electronic Brake force Distribution

A system that detects the difference in rotation between the front and rear wheels with a sensor and distributes the optimum braking effect to the front and rear  wheels. In order to maximize the effect of ABS, it is especially installed in trucks and minivans where the load on the rear wheels changes greatly depending on the number of passengers and the load capacity.

When the load weight is heavy, the braking effect of the rear wheels is strengthened to suppress the vertical movement of the vehicle, and at the same time, the steering of the front wheels is also effective.

There is also a specification that makes this work on the left and right wheels and realizes a stable braking effect when turning a curve.

●ESP/Electronic Stability Program

Electronic Stability Control (ESP) is a mechanism that prevents skidding when the vehicle turns, and is the name for Ford, VW, Benz, Chrysler, Audi, and Suzuki. This device is named by each car manufactures as follows.

Toyota: VSC, Nissan: VDC, Honda: VSA, Mazda: DSC, Mitsubishi: ASC,

Subaru: VDC, Daihatsu: DVS.  The mechanism to prevent skidding and spin by automatically giving brake instructions and engine output control to each wheel independently when it senses skidding of the vehicle body due to sudden steering operation when turning a curve.

●TCS/Traction Control System

When the accelerator pedal is depressed, too much force may be applied to the road surface and the tires may spin. TCS is a device that prevents this occurrence and efficiently controls the driving force. When the speed sensor and computer mounted on the four wheels detect the tire slip, the engine output is reduced to control the driving force and suppress the tire slip. Not only is it effective on slippery roads such as bad weather and rough roads, but it can also run smoothly when turning curves. It is generally called TCS including Honda, but it is also called TRC in Toyota and TCL in Mitsubishi.

●ASR/Anti-Slip Regulation

One of the kinds of traction control system. Adopted for vehicles with high engine output, it prevents from slipping tires by controlling both engine output and brakes.


Q. I need more information about the specification of DOT4 LV Superior Brake Fluid.

This product acquires DOT4 of the DOT standard established in “American Federal Motor Vehicle Safety Standards” (FMVSS) and JIS-K 2233 prescribed BF-4 standard of “Japanese Industrial Standards” (JIS), and Class 6 standard of “International Organization for Standardization” (ISO).
As Superior Brake Fluid DOT4LV is produced in JIS authorization factory and passes DOT and Japanese Industrial Standards, ISO standard, we recommend it with confidence.

Q. What is the characteristic of Superior Brake Fluid DOT4 LV?

A. DOT4 LV is the Low Viscosity type, and for the vehicle which electronic devices such as ESP (Electronic Stability Program), ABS (Anti-lock braking System), ASR (Anti-Slip Regulation) were attached to brakes function for the safety improvement of the car, it shows very superior performance, and it characterizes it to be suitable for the movement of the latest braking system.
This type of Brake Fluid is recommended for European cars in particular because of showing their original performance.

Q. What is the difference between Superior Brake Fluid DOT4 LV and general DOT4?

A. It becomes the big difference that Superior Brake Fluid DOT4 LV is Brake Fluid where the fluidity at the low temperature level is superior to a product classified in a standard of general DOT4.
The meaning of LV of the brand name shows Low Viscosity (low viscosity).

Q. What is the benefit of excellent cold fluidity?

A. There is an item measuring kinetic viscosity at -40 degrees Celsius in the standard of Brake Fluid even if brakes are used in cold districts and the winter season so that a braking system can operate normally. It may be said that Brake Fluid with the low kinetic viscosity is superior in responsiveness, communicability. Superior Brake Fluid DOT4 LV has lower -40 degrees Celsius kinetic viscosity with 628cst (※ representative figure) than general DOT4, and even a low temperature level Superior Brake Fluid DOT4 LV shows the best performance.

Q. Except for low temperature, is it too soft and the braking effect becomes poor?

A. It’s no problem. Superior Brake Fluid DOT4 LV can be used in stable from the high temperature to the low temperature area, because the kinematic viscosity is not a big difference between high temperature and low temperature compering with general DOT4.

Q. What is the difference between Superior Brake Fluid DOT4 LV and Super DOT 4.

A. The name of “Super DOT4” might be used for the differentiate “high efficiency Brake Fluid” which is higher in the boiling point than general DOT4. The standard called “Super DOT4” does not exist, and the classification just actually becomes DOT4.
It becomes the big difference that “Super DOT4” does not maintain the fluid good point at the low temperature level characterizing the maximum of “Superior Brake Fluid DOT4 LV”.

Q. What kind of vehicle does it suitable?

A. In recent years, Brake Fluid carries a sensitive role on EBD, TCS including ABS carried by most vehicles because delicate control is required by the spread of brakes servomechanisms and the evolution of these electronic devices.
From this, it is in an important factor when it operates a safety device incorporated in a braking system even in the low temperature area that kinetic viscosity is severer than the normal temperature that is in an always soft state has superior fluidity. It may be said that it is most suitable for the vehicle with these functions.

Q. Since the brake reservoir tank is low on fluid, can I add it?

A. There is a line indicating upper limit (Max) and lower limit (Min) when you look at the reservoir tank well. It is not any problem if there is Brake Fluid in Max and Min in reservoir tank, but it is necessary to add if the lower than Min. But be sure to add not exceeding Max label, because Brake Fluid is more likely to overflow by thermal expansion. When spilled Brake Fluid hangs over the vehicle, metallic corrosion is caused, and the trouble of detachment and parts of the painting as it might be connected.
It is recommended the same standard Brake Fluid in the tank when it is added.

Q. Why Brake Fluid in the reservoir tank decreases?

A. Small amount of Brake Fluid evaporates, but the big cause that quantity decreases is caused by the abrasion of the brake pad. A constant gap is necessary for a disc rotor and a pad, a brake drum and lining. A self-adjustment device works to keep a fixed this gap. In other words, 『A pad and lining are worn -> A gap grows big -> Self-adjustment (cylinder piston progress) of the gap -> Quantity of oil in the cylinder increases -> The surface of the reservoir tank decreases. Because the disc brake in particular has a big cylinder diameter, a surface change by the abrasion of the pad becomes big.

Q. Even if the reservoir tank contains DOT4 Is it okay to fill with DOT4 LV?

A. It is recommended that Brake Fluid of the same performance (product) is added, but may supplement it if it is a product of the glycol (non-mineral oil) when there is less Brake Fluid than lower limit line (Min). However, the ability of Brake Fluid would follow the low performance when the different type of Brake Fluid added. Therefore, it is recommended gross quantity exchange to show their performance to the maximum.

Q. I need more information about the exchange cycle of Superior Brake Fluid DOT4 LV.

A. Because there is absorbency in Brake Fluid, the boiling point lowers in around two years and makes at great risk of the vapor lock. It is said that the most important maintenance is periodic gross quantity exchange, and Superior Brake Fluid DOT4 LV is the same. However, the early exchange would be recommended when deterioration progress by use environment and the situation from the last time exchange even if it is less than two years. When the color of the liquid turns black, and a change of color is greatly seen other than the black, the early exchange is also recommended.

Q. How do I store brake fluid?

A. It is recommended indoor storage to avoid high temperature and humidity. In addition, be sure to seal the cap of the container tightly by all means to prevent an invasion of garbage and the water. It will be in a very dangerous situation when mixture of an alien substance and the water in Brake Fluid.

Q. New brake fluid was colorless and transparent, but it turned yellow during store unused. Can it be used as it is?

A. Yes, you can use it. The color of additives such as “an antioxidant” or “rust preventing agent” changes in yellow with progress of storage, and this color change doesn’t affect the performance of Brake Fluid. So, you can use it without any problems.

Q. Is there any cars DOT4 LV-designated in Japan?

A. Toyota, GR Supra is DOT4 LV standard-designated car. Power system or the drive system including the engine are developed jointly with BMW company, and it is a reason that specifications, the technique of the European car is reflected. DOT4 LV which does not penetrate in Japan, to be fluidity at the low temperature level while maintaining performance of the normal temperature area is becoming standard by European car.

Q. Is it okay if Superior Brake Fluid DOT4 LV is used for Japanese car?

A. There is no problem. It can be used as a replacement general DOT3 and DOT4.

Q. Is it okay if Superior Brake Fluid DOT4 LV is used for an old European car?

A. There is no problem. It can be used as a replacement general DOT3 and DOT4.

Q. Is it okay if Superior Brake Fluid DOT4 LV is used for American car?

A. There is no problem. It can be used as a replacement general DOT3 and DOT4.
