What will the high speed brake disc on my car call on?

Hello, this is likely to be the brake disc and the brake disc baffle between the pebble generated, or the brake pad material, there may be hard points, rush to step on the brakes a few times to try it, the general problem is not big, it is recommended that you take the time to go to the repair plant to take a look, open rest assured, hope, thank you.

First of all, you have to distinguish between the sound of abnormal noises, whether it is screaming, muffled, or screaming.

1. If it is screaming, first check whether the brake pads are about to run out, there is an alarm iron plate on the brake pads, when the brake pads are ground to a certain extent, this iron plate will contact the brake disc, and there will be abnormal noise when you brake, which proves that your brake pads need to be replaced. If it is a new film, then check whether there is a foreign object clamped between the brake disc and the plate, if there is a foreign object in the middle, the product will make an abnormal noise when you brake, and check whether there are any abnormal scratches from the brake disc.

2. If it is muffled, it is mostly a problem with the brake caliper, such as the wear of the movable pin, the fall off of the spring blade, etc.

3. If it is called, then there are more problems, calipers, brake discs, brake pads may have problems. If the sound is continuous, first check whether there is drag, poor caliper reset will cause the disc to rub against the disc for a long time, and under certain conditions, it will make abnormal noise. Then check whether there is any foreign object stuck between the disc and the disc.

If it is a new film, it depends on whether the brake disc is grooved, because local friction will cause abnormal noise. If there is no problem with the disc, then consider whether the brake pads are too stiff or the muffler is installed incorrectly. If it only rings when braking, it is mostly because the brake pads are too hard.

To sum up, the brake is a caliper, brake pad and brake disc, and all three may produce abnormal noise. But often people blame the brake pads for the problem.

For the various factors of the above products, not only the brake pads can occur, but if the brake pads have excellent performance, it will also greatly reduce the possibility of the above-mentioned abnormal noise. In terms of the current domestic market, the brands with better performance are, foreign brands: Firodo, Durable, Believe, Dr., Akipolo, etc.; The disadvantage is that it is high and cost-effective; Domestic:

A number of brands such as Jihong, Xinyi, and Golden Kirin have good performance. For the above brands, I prefer domestic products, not to say anything to support domestic production, I personally think that the performance of domestic brake pads is not much different from foreign ones, domestic base macro brake pads, I compared with the previous use of a foreign film, I think the performance of domestic products is better,

Hello brake disc ringing is due to a variety of reasons, here are some of the common ones:1Brake disc wear:

If the brake disc is worn, there will be a rattle. When the metal disc inside the brake disc begins to peek, the sound of friction causes the brake disc to rattle. 2.

Brake failure: When a brake fails or weakens, it can cause the brake disc to ring. Brake failure can be caused by a failure of a component such as a sensor, hydraulics, or wheel finger bearing.

3.Thermal expansion and contraction of the brake disc: When the brake disc is overheated due to the braker's operation during driving, the brake disc will make a sound due to thermal expansion and cold contraction.

4.Brake Dust Cover Corrosion: In bad weather conditions, the dust cover can corrode due to rain or mud.

If the corrosion level becomes more severe, it can have an impact on the braking system and the brake discs will rattle. If the brake disc makes a noise, you need to go to the vehicle repair shop for inspection and repair as soon as possible to avoid affecting the braking effect and driving safety. <>

Hello dear, the reasons for the brake disc ringing are as follows:1Brake disc wear:

When the brake disc is overworn, a brake sound will be felt. This is due to the fact that the brake pads do not fit snugly to the surface of the brake disc, resulting in ecological noise when the brake disc rubs2Brake pad aging:

Brake pads have a limited cycle and have been used for a long time and start to age, which will cause brake noises. 3.Rusty brake discs:

If the brake disc is not used for a long time, it will cause rust on the surface, resulting in brake noise. 4.Brake system problems:

The brake axle is due to problems with the braking system, such as the hydraulic pressure of the brakes, the sensitive closing of the brakes, and the damage of the components.

Brake discs ring for the following reasons:

1. The sub-pump is rusty. If the brake fluid is not changed for a long time, the brake oil will deteriorate and cause the sub-pump to rust and cause abnormal noise, which needs to be derusted.

2. The return of the main pump is slow. The brake master cylinder returns slowly, and the sub-cylinder returns abnormally, resulting in abnormal noise of the brake disc, which may be caused by the aging of the return spring, and the spring can be replaced.

3. The run-in period of the new car. The brake pads and brake discs of the new car will also make abnormal noises when they are in the running-in period, which is a normal phenomenon and does not need to be treated.

Category of brake discs.

The brakes have disc brakes, drum brakes and air brakes, and many older cars have front disc and rear drums.

Many 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. But in the low-speed cold brake, the braking effect is not as good as the drum brake, ** more expensive than the drum brake.

Therefore, many middle and high-end cars 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 Hui slag, and there are many brake pots in China. It rotates when driving the Luxin car. 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 Ringing brake discs usually mean that the vehicle's braking system is faulty or overworn. For example, the effect of the friction pads of the brake disc and brake pad is reduced, or the brake system is affected by pollution and rust, which may cause the brake disc to ring. A common brake disc rat problem is excessive brake wear, causing metal-to-metal friction to cause a scratching sound.

Another possible cause is contamination of the surface of the brake disc and pads, such as sand, soil, and environmental contaminants, which can form a layer of material between the two, causing the brake disc to rattle. In order to avoid the appearance of brake disc ringing, the owner can regularly check and replace the brake parts, and ensure the stable friction performance of the brake disc and brake pads and reduce mechanical wear. In addition, the owner should also pay attention to avoid slamming on the brakes in the case of high humidity of the vehicle, so as not to submerge the braking system by water mist and affect the braking effect.

The vehicle has been flooded before, the vehicle's brake pads are freshly replaced, and the brake pads are exposed to air.

Causes of abnormal brake disc noise:

1. If the vehicle has been flooded before, or the owner has waded through water on the road, it will cause the brake disc and brake pads to be connected together due to rust, resulting in abnormal noise.

2. The brake pads of the vehicle are newly replaced. Because our old brake pads have been run-in with the brake disc on the road, they will complement each other in a certain shape, and at this time, after replacing the new brake pads, there will be abnormal noise due to uneven contact with the brake disc.

3. Because the brake pads are exposed to the air, when driving or parking the vehicle, some foreign objects fly in between the brake plate and the brake pads, such as sand and the like, which will make a noise when braking.

4. If the owner of the car is disturbed by the emergency braking when there is a sound, don't worry, this is a normal phenomenon, because of the emergency braking, the vehicle's ABS start, resulting in the sound.

Brake discs.

The brake disc, also known as the brake pad, is a circular device, the brake disc will rotate with the wheel, and the brake caliper produces braking ability when rubbing the brake disc.

The Tongdan brake disc of motor vehicle is a circular disc, when the motor vehicle is in normal operation, the brake disc of the vehicle is also rotated, the brake disc of the vehicle is clamped in front of the brake card, so as to generate braking force, the brake disc can be clamped when the brake is stepped on, and the effect of deceleration or parking is played, the brake disc braking effect is better, and it is easier to maintain than the drum brake.

Hello brake disc ringing is usually caused by a problem with the braking system. A brake disc sound occurs when the brake disc is damaged due to excessive wear or external factors. Specific reasons may include the following:

1.Brake disc wear: When the brake disc is severely worn, the surface of the brake disc will become uneven and the beam will burn, resulting in a sound when braking.

2.Deformation of the brake disc: The brake disc may be deformed due to excessive heating or combustion by external force due to excessive heating or combustion of the rubber disc, resulting in uneven surface of the brake disc, resulting in a loud sound.

3.Brake pad wear: When brake pads are severely worn, the friction between the brake disc and the brake pad becomes unstable, resulting in a loud sound.

4.Brake system failure: Failure of other components of the brake system, such as brake calipers, brake cylinders, etc., may also lead to the sound of brake discs.

When the brake disc makes a noise, it is recommended to find a professional car maintenance technician for inspection and repair in time to ensure driving safety. <>

Hello Brake disc ringing means that when braking, the brake disc will make some screeching sound, which is usually a problem with the brake disc and needs to be overhauled in time. The main reasons for this are as follows:1

Brake disc wear: When the brake disc is worn to a certain degree of brightness, it will cause the surface of the brake disc to appear uneven, which will cause friction and noise during braking. 2.

Too hard or too soft brake pads: Brake pads that are too hard or too soft can cause the brake disc to rattle because the coefficient of friction between the brake pads and the brake disc does not match. 3.

Dirty brake discs: Dirt such as dust and grease accumulate on the surface of the brake disc, which will cause the friction ridge between the brake disc and the brake pads to be poor, resulting in a loud sound. In view of the problem of brake disc ringing, it is recommended to go to a professional car repair shop for repair and maintenance in time.

In daily use, it is also necessary to pay attention to the maintenance of brake discs and brake pads to avoid the occurrence of brake discs ringing due to long-term neglect of maintenance. <>
