Why did the Baojun 730 turn off and step on the brakes and not move

Because the vacuum required for brake assistance is gone.

The vacuum booster is a core operating component of the braking system, and the booster push rod is connected to the brake pedal; The brake master cylinder push rod is connected to the brake master cylinder, if the design of the car is not assisted, then the brake pedal is directly connected to the brake master cylinder with a rod can be seen that the whole booster is divided into two cavities by the diaphragm partition in the middle, when the brake is pressed, through the control of some valves, the chamber on the left will have a certain degree of vacuum, and the chamber on the right will communicate with the atmosphere. In this way, the pressure difference is generated. At this time, this pressure difference forms a leftward force on the push rod in the center, and together with the force of the human foot, it acts on the back parts, and the power is generated.

For naturally aspirated engines, the vacuum comes from the throttling effect of the intake pipe throttle; In the case of turbocharged engines, the vacuum comes from a vacuum pump. Space is not limited, if you are interested, you can open a separate topic to communicate. But whether it is a naturally aspirated engine or turbocharged, the vacuum can only be generated when the engine is running, after the ignition, the vacuum-assisted vacuum check valve ensures that the vacuum degree is enough to provide the driver with several braking assistance, if you continue to pedal, there is no continuous vacuum source, it can not provide assistance.

Because the vacuum required for brake assistance is gone. If mine is helpful to you, please set it to the best!

Hello, normal, the system is automatically locked, if my answer is helpful to you, please set it to! Thank you!

After the ignition is turned off, the brake can almost be used again, he is a pneumatic power brake, and only the handbrake is generally used after the ignition is turned off

It should be abnormal,It shows that the air in it is not exhausted when adding brake fluid, because usually when adding (especially changing) brake fluid, it will be mixed with air, for example, during the filling process, bubbles will be generated due to the flow of liquid (referring to the rapid injection of brake oil), so the air must be emptied after refueling, that is, in a stationary state, step on the brake many times, so that the pedal position is gradually raised to the point that it is difficult to step on.

Open the exhaust valve until the brake fluid flows out, close the exhaust valve, stop the flakes, and then step on the brake several times. This is repeated several times to ensure that the air is emptied, and once the air is removed, the brake fluid level indication is usually lowered, because the original air is mixed with it, causing expansion, and then the brake fluid needs to be refilled to the standard level.

The Baojun 730 is a 7-seater family car tailored by SAIC-GM-Wuling for the "Chinese family" based on the car needs of tens of millions of users. On March 1, 2019, the 2019 Baojun 730 CVT Edition was officially launched, including two models: CVT Fashion and CVT Flagship.

Hydraulic brake system. It could be that there is a sound of air flow when the brakes are slammed. An air leak is unlikely.

Baojun 730 car brake leakage check vacuum booster.

Hello, this possibility is small, go to the overhaul to see, if my answer is helpful to you, please set it to! Thank you!

The first thing to understand is the several elements of vehicle engine starting, which are the ignition system, fuel injection system, and timing system. These systems are all working properly and the engine can be started. Therefore, the common reason for the ignition system, fuel injection system, and timing system to fail is that the vehicle will turn off if the ignition system, fuel injection system, and timing system fails.

Ignition system: Generally, if the ignition system fails, the spark plug will not ignite, so the mixture cannot be ignited, so the vehicle will stall. At this time, it is necessary to check whether the ignition circuit in the ignition system is normal, whether the ignition module is working normally, and whether the spark plug is damaged, such as the pole is broken, and the ceramic part of the spark plug is cracked.

Fuel injection system: The fuel injection system is also what we often call the fuel supply system, which is generally transmitted to the fuel injector through the fuel pipeline through the fuel pump in the fuel tank of the vehicle, so that the fuel injection nozzle can inject fuel. If the fuel pump in this system is damaged, the lines are broken, the fuel injector is damaged, the fuel cannot be supplied to the engine to work, so the vehicle stops.

Timing system: It is connected to the crankshaft and camshaft of the engine by belt or chain, and the accuracy of the intake and exhaust time is ensured by the connection with the crankshaft and a certain transmission ratio. To put it simply, it is to control the opening time difference between the intake valve and the exhaust valve to ensure the normal operation.

Therefore, if the timing belt used is not replaced for a long time and causes it to break, the vehicle will suddenly shut down, because the intake valve and exhaust valve opening time cannot be opened or closed within the specified time, so the engine will be turned off. Therefore, it is advisable to replace the timing belt regularly.

If there is a failure of the above 3 systems, the first thing is that the vehicle will turn off, and secondly, it is impossible to start the vehicle again, and the vehicle can be started again after repairing and troubleshooting.

Summary. If you can't press the brakes now, it is recommended that you still press hard. It is possible that your vehicle has turned off and you have applied the brakes again, so this will cause your brake vacuum booster to not work and will not be able to step on it.

In this case, you only need to press the brake pedal hard, and then you can start normally, if you really can't press it, then you can lie on your brake pedal position and see that there is a switch above, you can rotate the switch directly counterclockwise to remove it, and then you can start it again. After activation, you can put this switch back in again, so that it can be restored.

The Baojun 730 can't step on the brakes, and it can't be started with one button.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

After the bumper is activated, you can bury the switch back and reinstall it, so that it can be restored.

No switch seen. Just above the pedals.

What shape. Not yet.

Can't you remove this switch?

Yes. Can you light up the meter now?

The indicator disc light flashes.

Then you're losing battery. Is it that the meter will go out when you start it, and the one-button start switch will light up again when you release it.

Start the dashboard flash, and wait for the dashboard to light up, a lot of confusion.

Yes, you are losing power in the battery, just find someone else to come and give you electricity.

If I can help you, please give me a thumbs up Thank you!

Summary. The solution to the fire can not be extinguished is as follows: 1. Directly disconnect the oil circuit switch, this mechanical oil circuit switch, due to the different layout positions of each car, some are under the seat, and some are under the left side of the steering wheel.

2. The electric injection diesel engine, which is the same as the key of the car engine, can be energized in the open state, and the ECU controls the fuel injector to inject fuel, so this kind of diesel engine is equivalent to turning off the work of the fuel injector, which is equivalent to disconnecting the oil circuit. <>

<> What is the reason why the Baojun 730 car can't go out?

Hello dear, the reasons why the Baohong 730 car can't turn off the fire are as follows: 1. The car can't turn off the fire after starting, it may be that the ignition opener has a fault, if the ignition switch has been in working condition, it will cause the engine to fail to turn off. <>

<>2. The ignition key switch of the car is faulty, which is also one of the common reasons why the vehicle cannot be turned off after starting. The frequency of use of the ignition key switch is very high, and it is also prone to serious wear or short circuit, which causes the vehicle to fail to turn off through the key switch after starting. Knowing the shouting <>

The solution to the <> can not extinguish the fire is as follows: 1. Directly disconnect the oil circuit switch, this mechanical oil circuit switch, due to the different layout positions of each car, some are under the seat, and some are in the direction of grinding the keyboard lower left. 2. The electric injection diesel engine, which is the same as the key of the car machine, can be energized in the open state, and the ECU controls the fuel injector to inject fuel, so the key of the orange tour high diesel ruler oil is equivalent to turning off the work of the fuel injector, which is equivalent to disconnecting the oil circuit.

If you step on the brake pedal, you can hear the "click" sound between the gearbox and the gear handle, the main reason for the sound may be the electronic linkage between the braking system and the automatic transmission gearbox.

If you step on the brake pedal when you step on the brake, you can hear the "click" sound between the gearbox and the gear handle, the main reason for the sound may be the electronic linkage between the braking system and the automatic gearbox.

It may be normal to have a rattling sound when stepping on the brakes (such as new car running-in, ABS work, etc.), but after all, the brake is an important part of driving safety, and it is best to go to a professional repair shop for maintenance.

Causes of the rattling sound when applying the brakes:

1. Excessive wear of brake discs and brake pads Brake discs and brake pads are high consumables for seepage keys, and the two parts of the brakes must be rubbed every time, and there will naturally be loss in the long run. Usually the replacement cycle of brake pads is 6-80,000 km, while the brake disc is 10-120,000 km.

2. If there is a problem with the assembly of brake pads, if the brake pads are installed in the opposite direction or the model is not right, then there will be abnormal noise, you can reinstall the brake pads, and when the car mainly installs the brake pads, it is necessary to go to a professional auto repair shop to carry out the operation, especially in the roadside stalls to replace the owners of the brake pads, you should pay more attention to this.

3. Other possible reasons are that the failure of calipers, brake discs and brake pads may produce this sound. 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. In addition, if there are foreign objects on the brake pads and brake discs, it can also cause strange noises.

Expand your information; Performance characteristics: the starter starts to rotate but the speed is not enough, that is, it is weak, and then the starter only clicks and does not rotate. Low temperature in winter and forgetting to turn off individual electrical equipment will cause the vehicle to be unable to start, especially in winter for long-term short-distance low-speed use, the battery voltage will be lower than the rated value, starting and unable to operate normally.

Emergency method laughing: If it happens, please call the service station to rescue**, or find a car to the object, or temporarily on fire, and then you must go to the service station to replenish the battery.

The reasons for the failure of Baojun 730 to climb and turn off the ignition are: 1. Blocked fuel injectors, oil leakage from oil pipes, reduced power of gasoline pumps, and blocked gasoline filters; 2. In addition to oil, the engine also needs air, if the air filter and throttle and other components are blocked or there are problems, resulting in insufficient air intake; 3. Poor ignition; 4. At least one cylinder of the car's engine is not running properly or stalling; 5. Insufficient tire pressure.

Poor ignition of flower plugs; 4. At least one cylinder of the car's engine is not running properly or stalling; 5. Insufficient tire pressure.

There are many reasons for the sofa yulinfeng: a. Ignition system: such as spark plugs, high-voltage wires, ignition coils.

Great Wisdom. Wait. b. Check the oil and water first, whether the oil is or off topic?

Is there or is no gasoline? Is there a shortage of engine water or antifreeze or is there enough of it? If the lack of water causes the cylinder gasket to be flushed or the cylinder is strained, the possibility of weak refueling or flameout may ......In addition, there are many aspects of inspection.

c. Check the oil pump to see if there is oil supply or abnormal oil pressure. Is the gasoline filter clogged? The throttle body has no cabel or smudges.

d. What is the blockage of the fuel injector line and the fuel injector? Is the line normal?
