What is brake fluid? Is brake fluid brake fluid?

in the endBrake fluidWhat is it, in fact it is what we often hearBrake FluidIt is a functional liquid (medium) used to stop the rotation of the wheel. It not only plays the role of transferring energy, but also has the functions of anti-corrosion, rust prevention and lubrication. It can be said that it is an indispensable part of the brake system. If it is classified according to the different raw materials, there are three types of automobile brake fluids, namely, alcohol type, synthetic type and mineral oil type.

Castor oil-alcohol type:It is made of refined castor oil 45%-55% and low-carbon alcohol (ethanol or butanol) 55%-45%, but this type of brake fluid is not so good in terms of resistance and low temperature fluidity Ideally, it leads to a certain degree of danger during driving. With the increasingly stringent national regulations, alcohol-based brake fluids can be said to have been basically eliminated.

Synthetic type:It is made of ether, alcohol, ester, etc. mixed with additives such as lubrication, anti-oxidation, anti-rust and anti-rubber swelling.

Mineral oil type:It is made of refined light diesel oil fraction with thickener and other additives.

Brake fluid is also one of the consumables of the car, but it is different from the oil andGlass of waterIn comparison, the replacement cycle of brake fluid may be relatively slow, usually every 2 years or 4000 kilometers. However, the replacement cycle can only be used as a reference, and the final decision must be based on the real-time situation. If you feel that the texture of the brake is significantly softer, or even feel that the car cannot be stopped, then you have to check whether the brake fluid is oxidized or deteriorated. , If it exists, it needs to be replaced in time, otherwise there will be a certain safety hazard.
