Trina Solar Automotive Group (TRW) is the world's leading supplier of automotive safety systems and one of the largest automotive parts companies in the world. It serves all the major automobile manufacturers in the world and is in a leading position in every product category involved. It is the only aftermarket manufacturer that produces all the main components of the brake system (including brake linings, brake discs, calipers, brake master cylinders, brake cylinders and other products).
Tianhe has a history of producing brake parts for over 100 years. Its DOT3, DOT4, DO4EPS and Grand prix Fluid brake fluids are suitable for vehicles in different regions and seasons, and meet the requirements of fast and safe braking of vehicles under any circumstances.
1. Product introduction
Product type: alcohol-based brake oil
Origin: England
Product parameters: dry boiling point: 240 degrees Celsius wet boiling point 149 degrees; C The kinematic viscosity at low temperature is 1270cSt (domestic standard: dry boiling point: 205 degrees Celsius, wet boiling point: 140 degrees Celsius).
2. Brake oil knowledge
(1)DOT minimum boiling point standard data
Type of brake oil (alcohol base)
Dry boiling point
DOT3 205 degrees Celsius
DOT4 230 degrees Celsius
DOT5. 1 270℃.
Wet boiling point
DOT3 140℃.
DOT4 155℃.
Dot 5. 1. 190℃.
(Test standard note: 1. Dry boiling point refers to the boiling point just after adding the braking system from the sealed container; 2. Wet boiling point refers to the boiling point with water content of 3.5% after 2 years of use);
(2) Suggested conditions for replacing brake oil:
Absolute standard: those with boiling point equal to 180 degrees Celsius must be replaced ... LUCAS provided a brake fluid boiling point tester with the number YWB 2 1 1.
General standard: the maintenance materials of general automobile manufacturers are recommended to be replaced once every two years. Unless you have a boiling point test, it is difficult to say the absolute replacement time. For example, the wheel is immersed in water, and the brake cylinder is completely immersed in water. Even if the brake system is well sealed, the water content of brand-new alcohol-based brake oil will exceed 3% after 7 days and reach 7% after 35 days! Therefore, in addition to the replacement standards of automobile manufacturers, it depends on your use environment. If the brake oil has flooded the car for only one year, I think it is necessary to change the brake oil immediately for safety reasons;
Special case: DOT5. 1 can significantly increase the replacement cycle. Generally, the normal average replacement cycle can be about 5 years. Because the MTG borate used is basically the same as DOT4, it can be compatible with DOT4. At present, it is mainly used for vehicles with high requirements such as racing cars.
