First of all, as long as it doesn't catch fire, it's normal for the brakes to be hard and not moving, as is the case with all cars.

The reason why the brakes are hard and cannot be stepped on is because we need the help of the vacuum booster pump when we apply the brakes. To put it bluntly, if the vacuum booster pump does not have assistance, the brake will have no assistance, and it will naturally be difficult to step on.

If the vacuum booster pump wants to produce power assistance, it must be after the car engine works, and the vacuum booster pump can generate a vacuum. When the engine doesn't work, the vacuum booster pump naturally stops helping.

Sometimes, you can step on the brake a few times without ignition, because relying on the little vacuum power left before, it is generally gone after a few steps.

As for the car not catching fire, there are too many reasons involved. Here are a few of the more common examples:

1. The steering wheel is locked. If you turn the steering wheel after the car is parked, the steering wheel will lock. This is the anti-theft feature of the car. Solution: Turn the steering wheel to ignition.

2. The battery is out of power. The phenomenon is that the engine squeaks when it is a little hot. Solution: Replace the battery or find a car to take the battery.

3. Failure of the engine itself. If this is the case, you can only go to a 4S shop or a professional auto repair shop to check first to determine where the problem is and then fix the symptoms.

The brakes are hard because the vehicle does not start and there is no vacuum assistance, so it will be very hard. There are two situations, if you step on the brakes lightly, because there is no power boost, it is possible that the brake switch is not completely disconnected, so it cannot start, in this case, you can step on it hard and start again. If you step on it hard and can't start, there may be other problems, such as the battery is out of power, the oil pump is broken, etc., and you can only find someone to repair it.

First of all, you need to check whether this phenomenon is caused by the loss of battery power? If the battery is out of power, you need to charge the battery or replace it with a new one.

In the case of making sure that the battery does not lose power, focus on checking whether there is a problem with the vehicle starter or whether the anti-theft is locked? If there is a problem with the starter, you need to check the corresponding control circuit of the starter or replace the starter. If there is a problem with the anti-theft system, you need to re-do the anti-theft matching.

The second major aspect is that the vehicle engine can rotate, but does not catch fire, so in this case, it is important to check, is the gasoline pump oil pressure insufficient? Or the vehicle engine does not ignite, if the pump oil pressure is insufficient, this situation requires the gasoline pump to be replaced. Check the fuse or wiring of the gasoline pump.

If ignition is not required, focus on checking the crankshaft position, sensor and ignition coil.

Question: The car doesn't catch fire.

Ask how to determine if the battery is losing power?

Question: I can open it when I was on fire yesterday, but I feel a little weak and powerless, and I can only open it after a few turns.

Is this feeling of running out of power?

Question: Before this, my engine failure light was on yellow for a while, and occasionally the automatic start-stop light and the triangular exclamation mark light in the lower right corner were also on.

The brakes do not move and cannot catch fire due to the following reasons: the car steering wheel is locked, the vacuum of the booster pump disappears, and the car battery is dead. The details are as follows:

1. The steering wheel of the car is locked. After the key is inserted, turn it in the normal ignition direction, do not turn to the end, and gently turn to the battery switch. After the car is powered on, gently move the steering wheel left and right, and if the steering wheel can be moved, then step on the brakes to ignite.

Remember to turn the steering wheel back to the right in the future to avoid the same problem again.

2. The vacuum of the booster pump disappears. It may be due to the fact that the driver stepped on the brakes several times after the car turned off, so that the vacuum of the booster pump of the brakes disappeared, and the brake pedal could not be pressed because there was no help of the booster. At the same time, the booster pump cannot work when the car is turned off, so it is recommended to try to re-ignite it a few more times, spend some effort to press the brake pedal, and wait until it starts to return to normal.

3. The car battery is dead. In this case, also according to method one, after inserting the key, twist it to the battery switch, observe whether the driving display screen is energized, if you can't judge, turn on your car lights to confirm again, and confirm that the battery is out of power if the lights are not on. At this time, you need to assist in taking electricity or replacing the battery, you can call your insurance company to rescue **, let him provide electric rescue, usually in the city and county, are free.

Find a nearby repair shop and clear the fault before continuing driving.

How to solve the problem that the car does not catch fire First of all, it is clear what causes it, the most common reasons are battery failure, aging or damage to the ignition system and self-locking of the steering wheel. Due to the power loss of the battery forgotten to turn off the electrical equipment on the car, the remaining power can not drive the starter to run to start the engine, and the solution is to use the electric treasure or find the electric vehicle to take the electric start.

Here are the reasons why the car won't catch fire and the brakes won't stop:

1. Steering wheel locked: The steering wheel of the car is lockedThe battery is dead :

The role of braking is to slow down or stop the vehicle. Its working principle is to use the friction between the brake pads and the brake drum and the tires and the ground to convert the kinetic energy of the vehicle into heat energy after friction, so that the vehicle can slow down or stop.

2. Cause of brake failure: there are impurities in the brake master cylinder, and the seal is not tight; Vacuum booster pump failure; The brake fluid is too dirty; Oil leakage from master cylinder or sub-cylinder; leakage at the interface of a gas tank or pipeline; severe overload; Brake hub carbonization; The master cylinder lacks brake fluid; The piston of the master cylinder is worn.

Hello, see if there is oil. I used to go to rescue a car with a friend, but the fuel gauge showed that it was below the red line, so naturally it couldn't catch fire. At the same time, pay attention to the quality of the oil. When we used to repair the car, we found that there was water and mud in the fuel tank after disassembling it, and with such oil, it was impossible for the car not to break.

No antifreeze added. Some car owners add water or inferior antifreeze to the car, resulting in a particularly cold winter, causing the entire waterway to be frozen, the engine to be frozen and cracked, resulting in the car water pump can not operate, can not catch fire, and injure other parts of the engine.

Check these two pieces first!

Questions. There is oil, there is electricity, but the battery may not have much power, before the loss of electricity a few times, screw the key door dashboard lit up, step on the brake and ignite can not hit, in the ignition brake will become hard, can not be stepped on.

The battery is a little, and I lost a few times the electricity, and there is no problem with the battery.

Questions. I'm also not sure if there is a problem with the battery.

Just because you said that the battery has electricity, so I will be the first to rule out the problem of the battery for you.

What are you doing automatic, manual, or truck.

Questions. Automatic.

Gearbox check if there is a problem!

If the battery is fine.

There is a high probability that there is a problem with the gearbox.

Normally, after turning off the engine and stepping on the brakes a few times, it will get harder and harder, because the brake power seems to rely on the vacuum state of the intake manifold after the engine starts. Therefore, if you suddenly turn off the engine during driving, you must brake urgently, and you must step on it once and do not let go, otherwise the power will be out of danger.
