Which is better, hzy3 brake fluid or hzy4 brake fluid

Of course, it is HXY4, but it needs to be determined according to the specific model of the car.

Brake fluid is a liquid medium that transmits braking pressure in a hydraulic braking system and is used in vehicles with hydraulic braking systems.

Brake fluid, also known as brake fluid or force oil, its English name is brake fluid, which is an indispensable part of braking system, and in the braking system, it is used as a force transmission medium, because the liquid cannot be compressed, so the pressure output from the master cylinder will be directly transmitted to the sub-cylinder through the brake fluid.

The performance requirements for brake fluid are:

1. Good viscosity and temperature, low freezing point, good fluidity at low temperature;

2. High boiling point, no gas resistance at high temperature;

3. The quality changes little during use, and does not cause corrosion and deterioration of metal parts and rubber parts;

4. Long-term use does not produce precipitation and particulate matter.

Unified force synthetic brake fluid HZY4 (DOT4) Its product characteristics are: fast conduction speed, sensitive braking, HZY4 (DOT4): borate synthetic brake fluid.

It has excellent high-temperature stability and high-temperature gas resistance resistance. It has low sensitivity to water, low moisture absorption, and the boiling point is not easy to drop. Moreover, it is not easy to expand in contact with rubber, and has good compatibility.

It has excellent chemical stability and excellent corrosion protection for metal parts. This product has good low temperature fluidity at -50°C. It is suitable for all kinds of drum or butterfly braking systems that require the use of HZY4 (DOT4) products, and can be used in all seasons.

Hzy4(dot4): equilibrium reflux boiling point 255°C, wet equilibrium reflux boiling point 158°C.

Of course, hxy4 is good, the higher the level, the better!

DOT4 brake fluid is good. However, it needs to be determined according to the specific model of your car.

The hzy3 of the automobile brake fluid is a model number. The brake fluid of this car depends on whether it is universal, and basically the brake fluid is universal. The color of the brake fluid is generally light yellow, transparent, and impurity-free liquidAlso, if you open it and smell it, there will generally be no peculiar smell or anything like that; If it doesn't match, don't buy it.

Key Benefits:Find a piece of metalDrip the brake fluid onto it and bake it with fire, and the qualified brake fluid is not easy to evaporate; Put the fire close to the brake fluid, the inferior brake fluid with more methanol may ignite, while the qualified brake fluid is difficult to ignite. The boiling point of the equilibrium reflux of the brake fluid must not be less than 205If it's lower than this, don't buy it.

Hello, the brake fluid of this car depends on whether it is universal, basically the brake fluid is universal.

According to GB12981-2003 "Motor Vehicle Brake Fluid", the brake fluid is divided into HZY3, HZY4 and HZY5. They correspond to international dot3, dot4, and dot5 respectively. There are high and low levels of brake fluid, and the higher the level, the better the safety guarantee.

In general, it is recommended to choose brake fluid that meets the HZY3 standard for mini, medium and low-end cars, while it is recommended to choose HZY4 standard brake fluid for medium and high-end cars. Of course, there is no problem with choosing the HZY4 for mini, low-to-mid-range cars, and it is better. The HZY5 standard brake fluid is mainly used in the military industry, and is generally less used in civilian use, and is suitable for harsh conditions such as deserts.

This should be the brand model of some kind of brake fluid, and it is relatively more accurate to consult the official customer service of this automatic fluid.

The grade of brake fluid used in the car is determined according to the standard of brake fluid use of the car. Most models on the market use DOT4 brake fluid, so you should choose a reliable manufacturer when purchasing, and the higher the grade, the better. The national mandatory standard GB 12981-2003 "Motor Vehicle Brake Fluid" divides the brake fluid into two specification levels according to the size of the boiling point of the equilibrium reflux, namely DOT3 and DOT4, and the corresponding boiling points are 205 °C and 230 °C.

Brake fluid repentance purchase:

1.As much as possible, we will purchase products from manufacturers that provide supporting brake fluids for automobile factories for a long time to ensure reliable quality and stable performance;

2.Try to buy from qualified large-scale sales places to prevent counterfeit and shoddy products; It is best to use professional equipment for replacement, so that it is more thorough, so that there are no impurities left on the tall branches, and at the same time avoid air blockage.

3.In terms of type selection, it is best to consider choosing synthetic brake fluid, and do not buy obsolete alcohol brake fluid.

4.The brake fluid has the characteristics of water absorption, and there will be a decrease in boiling point, pollution and different degrees of oxidation and deterioration, and if it is not replaced for a long time, it will corrode the braking system and bring hidden dangers to driving. It is recommended that the brake fluid must be replaced once every two years or 40,000 kilometers.

5.The higher the level of brake fluid, the better, and the higher the level of brake fluid, the better the safety guarantee. In general, it is recommended to choose the brake fluid that meets the DOT standard for mini, medium and low-end cars, while the brake fluid for the DOT4 standard is recommended for medium and high-end cars.

Of course, there is no problem with choosing DOT4 for mini, mid- and low-end cars, and it is better.
