How often do you need to change brake pads and brake fluid

For brake pads, there is no standard time or number of kilometers traveled by the car, and a big factor in the replacement of brake pads depends on the owner's usual use of brakes. A lot of bad driving habits overuse the brakes, the brake pad must be 10,000 kilometers may have to be replaced, from generally speaking, a pair of brake pads walking 100,000 kilometers is no problem, the brakes are relatively few, such as often driving long distances, can even reach 150,000 kilometers.

Brake pads are a very important maintenance for driving safety, to have a sense of regular inspection, during routine inspection, to see the degree of wear and tear of the brake pads, if it reaches a critical point, it needs to be replaced immediately. Otherwise, the brakes fail, and then it is very dangerous. Some high-end cars will be equipped with brake pad warning lights, which will remind you to replace the brake pads, which also saves the owner from worrying and paying attention to the brake pads all day long.

Some people often refuel violently during driving, and refueling will inevitably cause the frequency of braking, and the frequency of braking has reached a very high level. This kind of driving habit can be seen everywhere on the road, and it is not a minority. With such a habit, it is estimated that you have to change the brake pads once every 20,000-30,000 kilometers.

When replacing the brake pads, try to choose a better brand, you can choose the original parts of the brake pads, the original factory must be more advanced in quality, but it will generally be more expensive. It is still a well-known brand that is more reliable, and the service life of the brake pads that are generally replaced is also longer.

3 to 60,000 kilometers need to be replaced. In the braking system of a vehicle, the brake pads are the most important object, and the quality of the brakes is determined by the brake pads.

The original brake fluid is changed every two years. The original brake fluid is generally replaced once every 2 years and 4w kilometers. If the brake fluid is not replaced in time, the brake fluid will be worn out due to long-term use, and the brake fluid will absorb moisture in the air, oxidation, deterioration, etc., which will cause serious consequences such as brake failure and weakening of braking force.

Ways to determine if you need to change your brake fluid:1. Test the water content in the brake fluid. If the vehicle's brake fluid moisture content is detected to be between 1% and 2%, then the brake fluid can be used normally, but if the moisture content in the brake fluid is already more than 3%, then the brake fluid should be changed immediately.

2. Observe the color and state of the oil. If the brake fluid becomes black and cloudy, replace it immediately.

3. The braking distance is significantly extended during driving, and the braking is soft. Even if you step on the bottom, you will feel soft. At this point, you should consider whether you should change your brake fluid or not.

Brake fluid, also known as automobile brake fluid, was used in early automobiles to use drum brakes for mechanical braking. With the development of hydraulic technology, safe and reliable hydraulic brake systems are widely used in automobiles. Brake oil in the car brake system plays a transmission role, we step on the brake pedal with our feet, through the assistance of the vacuum booster, push the brake master cylinder, the brake master cylinder pushes the brake oil, the power under the feet through the brake oil to the brake cylinder to which the four wheels belong, the brake cylinder pushes the brake pads, and the brake pads squeeze the brake disc to form a braking force.

If the brake fluid is not changed in time, it will cause the brake fluid to be turbid, the boiling point will drop, and the effect will deteriorate, resulting in brake failure! Because the brake fluid system will always be worn, and the low-end brake fluid impurities will lead to the brake pump accelerated wear and brake system oil blockage, expired brake oil brake effect is not ideal, just because the owner has been adapting to his vehicle for a long time, so it is not noticed. In order to drive safely, it is recommended to replace it immediately.

Now basically in the maintenance manual of every vehicle, you will be told that the brake fluid has a number of kilometers to change, basically at 40,000 kilometers or should be replaced in two years.

Do I need to change the brake fluid to change the brake pads? The answer is: no!

So what is the reason? The main reason is that the replacement cycle of brake pads and brake fluid is different, and it is difficult to "expire" at the same time under different service cycles; As far as the brake pads are concerned, they are generally replaced once every 60,000 kilometers, and the brake pads should be regularly inspected every 30,000 kilometers before replacement, check the remaining thickness and wear state of the brake pads, and replace them in time if there is any abnormality.

A brand new pair of brake pads is about centimeters thick, and if there is 3-5 mm left under normal wear and tear, it needs to be replaced; The front wheels are replaced more frequently than the rear wheels, and the left and right pieces should be replaced at one time, rather than just one of them.

The replacement cycle of brake fluid is 2 years or 40,000 kilometers to replace once, if the brake is obviously softer in the process of daily driving, or the brake can not be braked, then it is necessary to check the moisture content of the brake fluid in time, more than 3% of the time to replace in time. There is also a situation that the brake is still soft after replacing the brake fluid, so it is very likely that in the process of replacement, the brake oil pipe enters the air, and it is necessary to exhaust in time!

When changing the brake pads, there is no need to change the brake fluid, because the replacement cycle time of the two is different. The brake pads are inspected every 5,000 kilometers of the brake system, not only to check the excess thickness, but also to check the damage to the shoes, if the situation occurs, it must be properly handled. The brake fluid is generally replaced every 2 years or 40,000 kilometers, which is much longer than the brake pads.

You don't need to change the brake fluid at the same time when you change the brake pads. The operation steps for replacing the brake pads: 1. Before replacing the brake pads, you should first open the lid of the brake fluid reservoir in the engine compartment to see the height of the brake fluid page, if the brake fluid page is above the highest limit, the brake fluid should be sucked out to prevent the brake fluid from overflowing during the replacement process;

2. Prepare the brake pads to be replaced and remove the wheels where the brakes are located. In the process of dismantling, it is necessary to avoid wheel rim scratches and fierce regrets;

3. Remove the bolts of the brake caliper with a wrench combined with the sleeve, and then remove the brake pad (if there is a brake induction line, the brake induction line should be removed first). Observe whether the brake pads are overworn, or cracked, and replace them in the next step;

4. Since there will be a lot of sand or mud in the brake caliper, it should be cleaned with a rag, and then apply the previous silencer paste to prevent abnormal noise when braking;

5. Press the piston to the position where the piston pressure pump cannot be pressed, then install the brake pads on the brake caliper, install the new brake pads in place (those with brake induction lines should also be installed), tighten the guide bolts, and the installation is completed;

6. After installation, cover the lid of the liquid storage tank, enter the car and press the brake pedal a few times, and reset the brake. Then observe the brake fluid height and be within the appropriate height range. After changing, test the car to check whether the braking effect reflects the orange.

<> "Brake fluid fingers and brake pads play a vital role in the braking system.

It is usually not necessary to change the brake fluid when changing the brake pads, as they have different replacement intervals.

The brake pads are inspected every 5000 kilometers on the ridge, not only to check the remaining thickness, but also to check the state of the wear of the shoes, if there is a problem, it needs to be dealt with in time; The brake fluid is generally replaced every 2 years or 40,000 kilometers, which is much longer than the brake pads.

Of course, we also have to decide according to the real-time situation, if you feel that the texture of the brake cavity is obviously softer, and even feel that you can't brake the car, then you have to check the moisture content of the brake fluid, if it exceeds 3%, you need to replace it in time.

Changing brake pads does not necessarily require changing the brake fluid, but should be judged according to the actual situation.

Different from the replacement cycle of brake pads and brake fluid, it needs to be judged according to the actual situation of the vehicle, such as mileage, road conditions, driving habits, brake response sensitivity and other factors. Generally speaking, it is better to change the brake fluid once every 2 years or 40,000 kilometers.

Different models have different requirements for the replacement of brake fluid. It is recommended to check the vehicle instruction manual first. Brake pads need to be checked every 5000 km. If you find that the wear is severe, you need to replace it in time, so the replacement cycle is much shorter than that of brake fluid.

If you want a new car, you can use it for about 5 years before changing the brake fluid. The owner always pays attention to the condition of the brake parts, checks whether the brake fluid is sufficient, and whether the quality of the oil is reduced. The quality of brake fluid has a direct impact on driving safety, but many car owners will ignore this important part of vehicle maintenance.

To change the brake fluid, it is recommended to choose ** brand products. Inferior brake fluid has a very direct impact on service braking performance.

Brake pad replacement intervals:

1.For brake pads, there is no standard time and there is no number of kilometers traveled by the car. A big factor in the replacement of brake pads depends on the owner's usual use of brakes;

2.Many people who have bad driving habits and overuse the brakes will definitely have to change the brake pads for 20,000 or 30,000 kilometers. Generally speaking, 100,000 kilometers with a pair of brake pads is no problem, less brakes. For example, they often drive long distances, even 150,000 kilometers;

3.If there is brake fluid, there is no specific time to replace it. Generally, if the vehicle mileage is more than 50,000 kilometers, the brake fluid can be changed once.
