3 risks of being lazy to change car brake fluid
(Baonghean.vn) - Changing car brake fluid is something that every car owner must pay attention to. If you are lazy to change brake fluid, not only will the parts wear out quickly but it will also cause danger when traveling on the road... Below are 3 risks that can occur when you do not pay attention to your car's brake fluid.
1. Brakes not working
 |
Brake fluid is responsible for helping the vehicle's brakes work better and more closely when moving. When the brake fluid is not changed for a long time, the air bubbles in the brake fluid will compress, causing the pressure created by the pedal force and brake assist when used to create a situation where you do not brake even though you have pressed it all the way.
2. Brake failure
 |
When braking, a large amount of heat is generated in this part. If the brake fluid is not replaced for a long time, it will quickly boil, creating many air bubbles that quickly damage the vehicle's brake system.
3. Corroded parts
 |
On a new car, the brake system can be considered absolutely sealed. However, during use, the absolute sealing ability does not last long, water can penetrate the gaskets and rubber hoses, reducing the boiling point of the oil. When the brakes are applied frequently, the oil evaporates, creating air bubbles in the pipes.
In many cases, brake pistons and cylinders are pitted and rubber gaskets are swollen due to brake fluid mixed with water. They combine to create strong corrosive substances that destroy parts in the system and can create emulsions that clog oil valves...
Therefore, brake fluid should be changed periodically every 40,000km, or 2-3 years as recommended by the manufacturer.
* Steps to change brake fluid
-Check the current in the brake fluid with an galvanometer.The current should not exceed 0.3 volts. If it exceeds 0.3 volts, it means your oil is too contaminated with moisture.
-Remove old brake fluidby vacuum then should not be poured directly into the environment.
-Add new oil of the correct type and level. Close the lid tightly as soon as possible to prevent the oil from becoming contaminated with moisture.
-Brake pipe oil suctionby unscrewing the oil plug under the brake assembly, have someone else step on the brake pedal. Then close the plug, step on the brake, then open the oil plug. Repeat this process until new oil comes out. Close the plug tightly and transfer to the brakes of the remaining wheels.
-Double check by givingSlow down the car, tap the brakes to check the brake pressure.Then look again for leaks around the oil pipe, oil plug under the brake...
