Put the electronic handbrake to hang the D gear car does not move, pedal hard to move, there is a ru

In this case, either the brake pads are dirty in the middle, or the handbrake is stuck, resulting in can't let go, keep running with the brakes, immediately go to the repair shop or 4s to check, if you can help thank you.

This landlord should be because your tires have been soaked in the brake disc for a long time and rusty, it is recommended that the landlord go to the store to re-polish the brake disc and check it, and there should be no problem if you don't drive it too fast. In particular, the drum brake of the rear wheel must be removed and disposed of.

Hello This should be a brake hairpin, it is recommended to repair it as soon as possible.

1. The engine has abnormal noise.

Symptoms say that there is a lot of abnormal noise in the engine cabin, and most people also judge that it is the abnormal sound of the engine compartment based on the sound, which is usually a metal screeching sound or a howling sound.

Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.

Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

2. There is abnormal noise in the gearbox.

Symptom description: If there is a "rustle" sound inside the gearbox while the car is driving, and there is no more after pressing the clutch or accelerator, there will be a whistle-like sound when changing gears.

Solution: There are many transmission parts, and the reasons for the sound are more complex, so we should pay attention to whether it is related to a specific speed, such as some planetary teeth that sound at about 50km h.

Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission. Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault.

If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.

3. There is an abnormal sound in the door.

Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry a little about the failure of the body.

Solution: The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to judge whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slide grease can be used, while special door attachment grease is used for lubrication of glass regulators, door locking mechanisms, handle mechanisms, etc. inside the door.

In terms of brand selection, try to choose the commonly used brands in 4S stores, such as Kruber, Hotolube, Fox, etc. It is not advisable to use engine oil or ordinary butter, it will freeze in winter, and the harmful smell will affect your health.

As a common fault of the car, many people have encountered abnormal brake noise, as for the causes, the common ones are mainly as follows:

1. Normal abnormal noise: the abnormal noise at this time is normal when the new car has just been driven or just replaced with a new brake pad, because the friction has not yet been matched, and it can be automatically eliminated after only opening and running in for hundreds of kilometers.

2. Abnormal sound after being wet by rain: brake pads are generally made of iron, which will rust after being wet by rain, and there will be abnormal sound when stepping on the brakes, just grind off the rust.

3. Abnormal noise of brake pad configuration: it may be that the brake pad is reversed; or less assembly of screw parts; or the brake pads are too small to match the friction; Or use cheap brake pads, etc.

4. Abnormal sound of emergency braking: Sometimes in the process of telling driving, we will hear abnormal noise when suddenly braking suddenly, and the brake pedal may have vibration feedback, which is caused by the intervention of the ABS system, so there is no need to worry.

The above 4 situations are the situations we will encounter in daily life, and it needs to be reminded that if the brakes make abnormal noises for a long time, we must go to a regular 4S shop or an experienced auto repair shop to solve the problem, after all, braking is the first element of safety.

Regular maintenance and inspection contribute to the longevity of the car and the safety of the driver. There are thousands of roads, and safety is the first.

I hope mine can help you

Combined with the analysis of the following situation, if it is convenient, it is better to go to the nearest 4S store for inspection, safety first! The run-in of the new car, in which the run-in of the brake pads is a very important link, usually after running hundreds of kilometers, you can feel that the brakes will be more comfortable; The new brake pads also need to be run in to better combine with the old plate, when you first replace it, you will feel that the brakes are very hard, and you usually need to drive hundreds of kilometers to feel better; During the vehicle driving, there may be very fine sand particles into the middle of the sheet and the plate, and sometimes there will be abnormal noise due to friction, which generally does not need to be maintained, just run to make the small sand particles fall out; For those who do not have a good run-in and abnormal noise, some owners simply run up and slam on the brakes, so that the brakes can be run in in a short time, but this will make the brake pads wear more severely, that is, it is equivalent to reducing the service life of the brake pads, so it is recommended that you still run for a period of time to observe, do not artificially force the wear of the brake pads; Loss or damage of the fixing screws of the brake disc will also cause abnormal brake noise; If the brake system is faulty, it needs to be inspected and repaired If your car is equipped with ABS, it is also possible that it has intervened; When the brake disc is worn abnormally, this is due to the dirty surface of the brake disc, the uneven material density of the brake disc, the excessively high working temperature, and the mismatch of the brake disc installation torque.

There are three reasons for the abnormal sound of the automatic transmission P gear stepping on the brakes:1The sound of the gear lock.

Press the brakes, and at this time, the gear unlock is opened, and a click will be heard. 2.Parking to do a bang to hang the P gear did not pull the handbrake.

If parked on the slope, the car will still move forward or backward until the parking lock pawl locks the car, after locking, the vehicle's braking is to rely on the pawl locking, when the vehicle needs to move from P to the outward gear, it will first unlock the lock of the pawl, the sound you hear is the unlocking sound, the correct way to stop is: step on the brake to stop Pull on the handbrake Release the foot brake The car is parked and hung into the P gear. 3.

There is a deviation in the length of the steel back of the brake pads, you can step on the brakes and then hang the forward gear, then hang the reverse gear, and then hang back to the forward gear after the car moves, to see if there is that sound every time, if there is a brake pad gap is too large, of course, check the rear brake system, to see if all the bolts have been installed in place and tightened.

Summary. This sound appears when the brakes are applied in neutral position. If you step on the brakes, this is mainly because there is a brake control switch on the brake control pedal, and this sound will appear when you step on the brakes.

There is also this automatic transmission car, which has this shift control switch on this gearbox, that is, the shift control switch will be unlocked when the brake is stepped on, and there will be this kind of sound, this is normal, and there is no problem with normal use.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

Summary. Hello dear, when the vehicle is in red light, there is an abnormal sound when the vehicle is in D gear and the brakes are pressed. First, this situation is first considered to be caused by the gap between the half axle and the outer cage of the vehicle, and this phenomenon needs to be checked.

The second situation is the chassis-related support, and if there is a problem with the arm ball head, you need to check the ball head, and if there is a problem, it needs to be replaced. The third situation is that the engine of the vehicle or the fixed machine mat of the gearbox is aging, and the fixed machine mat needs to be checked. Kiss Blessings to you, good health and family, and if my answer is helpful to you, please give it a thumbs up.

Good luck! Good luck!

Finally, I wish you good health and <> again

Good luck! Good luck!

It's like a sudden sound under the front hood.

In this case, it is important to check the fixed floor mat.

Release the brakes and hang neutral, and the abnormal noise disappears.

There was a noise when parking, and the noise disappeared when the car was walking.

There is no load in neutral. There was definitely no abnormal noise.

The main causes of abnormal brake noise are as follows:

1. The run-in of the new car, in which the run-in of the brake pads is a very important link, usually after running hundreds of kilometers, you can feel that the brakes will be more comfortable;

2. The new brake pads also need to be better combined with the old disc through running-in, and when you first put it on, you will feel that the brakes are very hard, and you usually need to drive hundreds of kilometers to feel better;

3. During the driving of the vehicle, there may be very fine sand particles into the middle of the sheet and the plate, and sometimes there will be abnormal noise due to friction, which generally does not need to be repaired.

4. For those who do not run in well and have abnormal noises, some car owners simply run up and step on the brakes, so that the brakes can be run in in a short time, but this will make the brake pads wear more severely, that is, it is equivalent to reducing the service life of the brake pads, so it is recommended to run for a period of time to observe, do not artificially force the wear of the brake pads;

5. If the fixing screw of the brake disc is lost or damaged, it will also cause abnormal brake noise;

6. If the brake system fails, it needs to be inspected and repaired.

When the automatic transmission is on the brake, there will be a sound in the gear part because of the sound of the gear solenoid valve closing and opening, which is a normal phenomenon.

An automatic transmission uses a planetary gear mechanism to shift gears automatically depending on the degree of accelerator pedal and vehicle speed changes. The driver only needs to control the speed of the vehicle by manipulating the accelerator pedal. Generally speaking, there are the following types of automatic transmissions commonly used in automobiles:

Hydraulic automatic transmission, hydraulic transmission automatic transmission, electric transmission automatic transmission, stepless mechanical automatic transmission and continuously variable mechanical automatic transmission, etc. Most.

Hello. Because of automatic vehicles, when you press the brakes, the brake lights will have a signal. The electronic shift mechanism, the solenoid valve, will release the gear lock after receiving the signal.

Therefore, it is normal for the solenoid valve to have a sound when it works, I hope it can help you, and I wish you a happy car! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

It's the sound of the gear solenoid closing and opening.

It should be that your gearbox is faulty, and it is recommended that you check it out.

That's the gears decelerating.

The gear lever locks the solenoid valve and works on power.
