Can you change the brake disc or change a pair.

If a new car or a new pair of plates, found that one of them has a problem, then you can change one, if they have run thousands of kilometers or tens of thousands of kilometers, then you can only change a pair, otherwise there should be a problem with the brakes.

Brake discs. To put it simply, it is a round plate, and it also rotates when the car moves. If the brake caliper clamps the brake disc and generates braking force, it clamps the brake disc to slow down or stop when the brake is pressed.

Brake discs brake well and are easier to maintain than drum brakes.

The brakes are currently available in disc and drum brakes.

There are also air brakes, and many older cars have front discs and rear drums. Many of today's cars have disc brakes front and rear. Because the disc brake has better heat dissipation than the drum brake, it is not easy to produce thermal decay in the high-speed braking state, so its high-speed braking effect is good.

However, at low speed cold brakes, the braking effect is not as good as drum brakes. **More expensive than drum brakes. Therefore, many middle and high-end cars now use full disc brakes, while ordinary cars use front disc and rear drums, while relatively low-speed, and need large braking power for trucks and buses, still use drum brakes.

The drum brake is sealed, shaped like a drum, and there are many brake pots in China. It turns when driving. There are two curved or semicircular brake shoes fixed on the inside of the drum brake.

When stepping on the brakes, the two brake shoes are stretched outward under the action of the brake wheel cylinder, and the brake shoes are propped up and rubbed against the inner wall of the brake drum to play the role of deceleration or stopping.

Hello, this case can be replaced with just one.

Summary. If the car replaces the brake disc, it is best to replace the brake pads at the same time, because the surface of the brake disc is uneven, and if the old brake pads are used with a new brake disc, then it will cause your new brake disc to wear irregularly. On the one hand, it will accelerate the wear of the brake disc, and on the other hand, it will also lead to the deterioration of the braking effect, so it is generally necessary to replace the brake pads at the same time when replacing the brake disc, and the brake pads need to be replaced once if the brake disc is replaced twice, so it is recommended that you replace it at the same time.

Do I need to replace the brake pads at the same time to replace the brake disc? I only replace the front brake disc. The front brake pads were replaced a year ago, and they only drove about 10,000 kilometers after they were replaced.

If the car replaces the brake disc, it is best to replace the brake pads at the same time, because the surface of the brake disc is uneven, which will cause the surface of the brake pads to be uneven, and if you use the new brake disc and the old brake pad, it will cause your Li Han's new brake disc to wear irregularly. On the one hand, it will accelerate the wear of the brake disc, and on the other hand, it will also lead to the deterioration of the braking effect, so when the brake disc is replaced, it is necessary to replace the brake pads at the same time, and the brake disc needs to be replaced once if the brake disc is replaced twice, so it is recommended that you replace it at the same time.

This can take a look at the surface wear of the brake pads, if the brake pads are now not on the surface of the Xiang Grill without the regular shape of the shirt, then you can continue to use, if the surface of the surface is irregularly worn and there are some dents, then it is recommended that you directly replace the new.

Do you have to change it after only a year, brake pads.

Didn't I just pretend to be bright, you need to see a mess according to your actual situation, if there is no dent on the surface, or the thickness of the brake pads is relatively thick, you can also use sandpaper to polish it, and smooth the surface.

I didn't brush it out just now.

Good. Good. It's to let the master take a look at it on the spot. Good.

<> "The car needs to replace the brake pads, many car owners and friends will replace the brake discs when replacing the brake pads, and some car owners think that they do not need to be replaced. Respectful.

When changing the brake pads, you don't need to change the brake disc, because the service life of the brake pads is shorter than that of the brake disc, and the brake pads are generally replaced 2 or 3 times before the brake disc needs to be replaced. However, it is not excluded that there is a problem with the brake disc in advance, and whether the brake disc needs to be replaced or not needs to be judged according to the degree of wear of the brake disc.

The brake disc of the car has been used for a long time, and there will be small grooves on it, and the owner can polish off the small grooves on the brake disc, and the brake disc can continue to be used; Although the car brake disc is not very expensive, it is not necessary to replace it from the perspective of environmental protection, and the parts of the car do not reach the service life of the stove.

The owner of the car should develop good driving habits, do not always brake suddenly, check the wear and tear of the brake pads and brake discs every day, and replace them in time if there is a problem.

The brake disc should pay attention to the use of the problem, if the brake disc has a certain failure, it needs to be replaced, if the brake disc is still very good, then it does not need to be replaced.

No, you don't. Because the brake disc is more wear-resistant and has a longer service life, the brake disc does not need to be changed the second time you change the brake pads.

In general, it is not needed, but if the brake disc is badly worn, then it must be replaced.

It is not necessary to change the brake pads to change the brake disc, if the brake pads are still very thick, you can replace the brake disc without changing the brake pads.

The use of reliable quality brake discs can ensure its service life of 8-120,000 kilometers. If counterfeit or inferior brake discs are used, braking efficiency can be produced in a short time, but for long-term use, the brake discs are easily deformed due to the high temperature caused by friction, reducing the braking effect and ultimately affecting driving safety.

When replacing the brake pads, it is not necessary to replace the brake disc together, and the replacement of the brake disc depends on the thickness and wear of the brake disc.

Most brake disc products have a wear indicator, which means that there are 3 small dimples on the disc. Measure the depth of the hole with a vernier caliper, that is, the total wear depth of the brake disc on both sides reaches 3mm, and the brake disc needs to be replaced in time.

However, not all brake discs have wear indicators, and you can also use your hand to touch the extended side of the disc to determine the approximate depth, generally speaking, if the total wear depth of the brake disc on both sides reaches 3mm, the brake disc should be replaced in time.

The standard for replacing brake disc wear is about 2 mm, and if the brake disc is worn beyond this standard, it should be considered to be replaced. Generally, check the brake disc every 60,000 kilometers, and if it is found that the wear is more severe, it is necessary to replace the brake disc as soon as possible to avoid safety problems.

It is not necessary to change the brake pads and brake discs, which one is seriously worn.

In addition to the brake pads, the components of the braking system also include &ldquo brake discs&rdquo. Friends basically know that the brake system is the most important part of the car, and the brake is related to our lives, so we should pay special attention to this problem. Brake pads and brake discs are fragile and non-perishable parts of the car and should be replaced regularly.

Do I need to replace the brake pads and discs together? To solve this problem, let's take a look at whether the brake pads and brake discs need to be replaced together.

Do brake pads and discs need to be replaced together?

The brake pads of the brake disc do not need to be replaced together, it depends on the situation, as the brake pads are damaged more often than the brake disc. Most of them change the brake pads every 30,000 kilometers and change the brake discs three times. The replacement test is to touch the surface of the brake disc with your hands, and the new disc is smooth.

If you feel the scratches on the brake disc very clearly with your hands, and the depth of the scratches on the surface of the brake disc is different, then it is recommended that you replace the brake disc. The maximum wear limit of the new brake disc is 2 mm, and it is necessary to replace the brake disc with a new one after the limit has been used. The above phenomenon indicates that the contact surface between the brake disc and the brake pad will be reduced, and the braking effect will be reduced, which is seriously related to your safe driving.

Do brake pads and discs need to be replaced together?

When the brake pads wear out to the necessary limit (most of them have 2-3 mm left), they must be replaced. When changing brake pads, there is no need to replace the brake disc. Whether the brake disc is replaced or not depends on the situation.

For example, if the wear of the brake disc exceeds 2 mm (some models specify a wear of more than 1 mm), it must be replaced. Of course, if there is a little abnormal wear, the brake pads or discs must also be replaced.

Do brake pads and discs need to be replaced together? Good maintenance guide.

The braking system plays a vital role in the driving safety of the car, and a large accident can basically occur with the slightest negligence. Therefore, we should pay special attention to the braking system. Here are some things to keep in mind when using a car:

1.Under normal driving conditions, check the brake shoe every 5000 kilometers, not only check the remaining thickness, but also check the wear state of the brake shoe, whether the wear degree on both sides is the same, whether the return stroke is free, etc. If an anomaly is found, it must be dealt with immediately.

2.When changing the brake shoes, the brake cylinder must be pushed back using a special tool. It is not possible to use other crowbars to force back pressure, which is easy to affect the bending of the guide screw of the brake caliper and make the brake pads stuck.

After changing the brake shoes, it takes 200 km to get the best braking results. Newly changed shoes must be driven with care.

Both brake pads and brake discs are essential components and essential types. Generally speaking, brake discs and brake pads are basically the wearing parts of a car, but they do not need to be replaced together. Most of them say that brake discs need to be more durable than brake pads, and often a car needs to replace several sets of brake pads while the brake discs are still good.

If the brake disc is replaced, it is recommended to replace it together with the brake pads, at least the brake pads need to be polished. I hope that the information shared by the car about whether the brake pads and brake discs need to be replaced together can help friends better understand the problem.

Brake discs and brake pads do not have to be replaced together, it depends on the situation, because brake pads are damaged more often than brake discs. Generally, the brake pads are changed once every 30,000 kilometers, and the disc is replaced every three times.

The replacement check is to touch the surface of the brake disc with your hands, the new brake disc is smooth, if the brake disc has a very obvious scratch feeling when you touch it, and the depth of the scratches on the surface of the brake disc is different, then it is recommended to replace the brake disc. The maximum wear limit of the brake discs for new cars is 2 mm, and it is necessary to replace them with new ones. The occurrence of the above phenomenon indicates that the contact surface between the brake disc and the brake pad will be reduced, and the braking effect will be reduced, which will seriously affect the driving safety.

In general, brake pads and brake discs do not need to be replaced together. The replacement cycle of the brake disc is longer than that of the brake pads, and the front brake pads need to be replaced once for 3-50,000 kilometers and the rear brake pads for 6-80,000 kilometers under normal driving conditions. The front brake disc needs to be replaced once every 6-80,000 kilometers, and the rear brake disc needs to be replaced after about 100,000 kilometers.

The brake disc, also known as the brake disc, as the name suggests, is a disc-shaped disc, made of metal, which has a lot of pores, the car will rotate with the tires during driving, and the brake caliper clamps the brake disc, which will produce braking force and play a role in deceleration or parking. Brake discs brake better and are easier to maintain than drum brakes.

Brake pads are also called brake pads, made of ceramic, metal and carbon fiber, which are installed in the brake calipers, in the braking system of the car, the brake pads are the most critical safety parts, the quality of the brake effect is determined by the brake pads, the brake pads are generally composed of steel plates, bonding insulation layers and friction blocks, when the brakes are pressed, they will be squeezed onto the brake disc or brake drum to produce friction, so as to achieve the purpose of vehicle deceleration and braking.
