Tiguan brakes driving normally and suddenly locked?

There are many reasons for brake failure, one is the lack of necessary maintenance of the brake system, too many impurities in the brake master cylinder, poor sealing, vacuum booster pump failure, excessive dirt of brake oil or air resistance after the mixed use of several brake fluids, oil leakage of the brake master cylinder or sub-cylinder, air leakage of the gas tank or pipeline interface; The second is the failure of the parts due to improper operation, such as long-term downhill will cause the brake pads to rub and heat, the brake hub to carbonize, and the brake function to completely fail; Third, due to serious overload, under the action of gravitational acceleration, the inertia of vehicle movement is increased, which directly leads to brake failure.

What should a novice do if the brakes fail while driving?

1.Control the direction according to the road conditions and vehicle speed, disengage the high-speed gear, and at the same time quickly empty the fuel and shift the high-speed gear into the low-speed gear. In this way, the engine will have a lot of traction resistance and the speed of the vehicle will be reduced rapidly.

In addition, the handbrake should be used in conjunction with the low-speed gear shift, but it should be noted that the handbrake should not be tightened or pulled too slowly. If it is pulled too tightly, it is easy to make the brake disc "lock", and it is likely to damage the transmission parts and lose the braking ability; If it is pulled too slowly, the brake disc will wear and ablate and lose its braking effect.

2.Use the bumper, carriage and other rigid parts of the car to rub and collide with natural obstacles (rocks, trees or soil slopes) on the side of the road to achieve the purpose of forcibly stopping and getting out of danger, and reduce the accident loss as much as possible.

3.If the brakes fail when going uphill, you should reduce to the middle and low gear in time to maintain enough power to drive up to the top of the hill and stop. If you need to park on a half-slope, you should keep the forward low gear, tighten the hand brake, and the personnel with the vehicle should use stones, skids and other objects to jam the wheels in time.

If there is a backward slippage, the rear of the car should face the hillside or the safety side, and the headlights and emergency lights should be turned on to attract the attention of the vehicles in front and behind.

4.When the downhill brake fails and the speed of the vehicle cannot be controlled by the mechanism of the vehicle itself, the driver should decisively use natural obstacles, such as rocks and trees on the side of the road, to cause resistance to the car. If you can't find a suitable terrain or object to use for a while, in an emergency, you can move one side of the car closer to the side of the mountain, and gradually reduce the speed of the vehicle by rubbing to increase the resistance.

5.When the vehicle is descending a long slope or a steep slope, the vehicle should apply the brakes regardless of whether there is a situation or not. It can not only test the performance of the brakes, but also buy time to control the speed of the vehicle when the brakes are found to be out of order, also known as predictive braking.

If the Tiguan brake is suddenly locked when driving normally, it is a fault of the brake cylinder or master cylinder, and it is recommended to check this aspect of the car.

Summary. Hello <>

The reasons for the sudden seizure of the Tiguan brake during normal driving are: lack of necessary maintenance of the brake system, too many impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, excessive dirt of brake fluid or air resistance after mixing and heating of several brake fluids, oil leakage from the brake master cylinder or sub-cylinder, and air leakage in the air storage tank or pipeline interface. <>

Tiguan brakes driving normally and suddenly locked?

Hello [Smile Chun Weishi], the reason for the Tiguan brake normal driving and sudden hugging of the SI is: the lack of necessary maintenance of the brake system, too much miscellaneous bulk in the brake master cylinder, poor sealing, vacuum booster pump failure, brake fluid is too dirty or several brake fluids are mixed and heated, and the air resistance mountain skin appears, the brake master cylinder or sub-cylinder leaks, and the air tank or pipeline interface leaks. <>

<> extended information: the reasons for the brake holding SI: 1. The brake cylinder does not return, and the leather bowl of the brake master cylinder does not return to the rubber sock position.

2. The wheel placement static vacuum booster pump is faulty. 4. The ABS system is like a failure. The brake is that the wheels stop rotating after being subjected to strong braking force, and the car is still sliding forward due to the inertia generated by the speed of the vehicle, even if the wheels do not turn.

The brakes are locked and cannot drive normally. Brake locking is that the wheels stop rotating after being subjected to strong braking force, due to the inertia generated by the vehicle speed, even if the wheels do not turn, the car is still gliding forward; The installation of anti-lock braking device is to prevent the wheels from rotating, to ensure that the vehicle and the ground are not sliding friction, to ensure that the vehicle will not lose control, and the tires will not burst due to sliding friction.

The reasons for brake locking are as follows:

1. The leather bowl of the brake master cylinder is stuck and does not return to the brother mold. Generally, it is caused by water or other impurities entering the braking system, or the system is not cleaned before replacing other grades of brake fluid, resulting in the bubble expansion of the leather bowl of the brake master cylinder;

2. The problem of matching the inner diameter of the main cylinder leather bowl and the main cylinder. Such problems occur in the development stage, most of which are caused by the interference of the inner diameter of the main cylinder leather bowl and the master cylinder, which leads to the leather bowl not returning or poor return after stepping on the envy and slow stepping;

3. The piston of the brake does not return or is poorly returned, the material performance of the square sealing ring is poor, or the size of the square sealing ring and the inner diameter of the caliper and the caliper piston are poorly matched, resulting in the return amount of the square sealing ring is too small, resulting in wheel lag or even locking;

4. The stiffness of the brake disc is insufficient, when the braking system is deformed at high temperature due to the insufficient stiffness of the brake disc after frequent braking, the wheel may lock up in the next use after the brake disc is deformed.

If your brakes suddenly lock up during driving, of course, you should release the brakes as soon as possible, then press down again, and then pull over as soon as possible, or go to the 4S shop as soon as possible to check or replace your anti-lock braking system.

1. The piston of the brake master cylinder does not return (all four wheels are locked);

2. The piston of the brake cylinder does not return;

3. The return tension spring of the wear piece fails;

4. The ejector rod of the brake master cylinder is improperly adjusted, and there is no free stroke (all four wheels are locked);

5. The gap between the wear pieces is too small;

6. The normal valve of the vacuum booster fails.

If the speed is dangerous, if the speed is not fast, immediately hit the ** repair shop, there is no other way!

Pull over in time, you don't have the right tools for this, you need to wait for roadside assistance.

Second, the stiffness of the brake disc is insufficient, when the braking system is not strong enough due to the insufficient stiffness of the brake disc after frequent braking, the brake disc is deformed at high temperature, and the wheel may lock up in the next use after the brake disc is deformed.

3. Unreasonable brake pad matching brake pads were originally semi-metallic brake pads, and the brake pads and brake drums are easy to stick.

There are many reasons that affect brake locking, first of all, the brake stick. Sub-cylinders, ABS, brake hoses, and secondly, handbrakes can all cause brakes to lock.

1. Water ingress into the braking system.

Causing the blisters of the brake master cylinder to swell, which needs to be replaced immediately.

Second, the stiffness of the brake disc is insufficient.

When the braking system is deformed at high temperature due to the insufficient stiffness of the brake disc after frequent braking, the wheel may lock up in the next use after the brake disc is deformed.

The brake pads of the brake pads were originally semi-metallic brake pads, and the brake pads and brake drums were easy to stick, which was due to the problem of oxidized rust adhesion, and the formula of the brake pads needed to be reasonably determined in the design stage.

1.Take advantage of obstacles. If you can't grab it in the low gear, don't panic, at this time, you should carefully observe the road conditions, see if there are mountains, rocks, trees or dirt slopes around, and use the bumper, compartment and other rigid parts of the car to rub and collide with obstacles on the side of the road to achieve the purpose of forced parking.

It is necessary to pay attention to the steering wheel with both hands to avoid shaking the steering wheel and injuring the hand bones.

2.Try pressing the brake pedal a few more times to increase the chance that braking force will recover. When you find that the brake pedal is failing, you must try to release it and then press the brake pedal, which can make the brake equipment containing air in the oil pipe add pressure, and then with repeated pressure, you can increase the chance of braking force recovery.

3.Intermittent and short-term use of the handbrake to see clearly, it is not a one-time pull of the handbrake and it is over, it is an intermittent short-term handbrake pull. The vehicle downshifts, and after the speed of the vehicle drops, the handbrake is used intermittently for a short time, relying on the handbrake to finally bring the vehicle to a complete stop.

Remember, be sure to pull the handbrake quickly and then put it down immediately, and do it quickly. Because if the handbrake is forcibly pulled, it will cause the handbrake line to be broken or the vehicle to lose control. Therefore, the car can only be forced to automatically downshift by frequently pulling the handbrake.

4.Turn on the emergency lights to alert nearby vehicles. In the emergency situation of brake failure, many drivers only think about how to slow down the vehicle, and ignore the warning of the surrounding vehicles.

There is nothing wrong with this, but if you take slowing down measures and turn on the double flashes and honking the horn to attract the attention of the surrounding vehicles, the success rate of self-rescue will be higher.

5.Stay calm at all times. When the brake system is found to be out of order, the driver must be calm, do not panic because of the loss of control, and do not step on the brake because of the failure, which is counterproductive. Calm, calm, and adjust your mentality can minimize losses.

Hello, first detect whether it is four rounds of locking or which one,

If there is a sudden lock-up, then the only way to do this is to immediately turn on the vehicle's double-flashing fault lights to see if you can move the car to the side of the road.

Hello car owner, the brakes in the form of sudden satiety need to be calm, control the direction of the vehicle, do not turn sharply, to avoid the vehicle slipping out of control, now the vehicle will not appear suddenly full under normal circumstances, to maintain frequently, check more.

If the tires of the car suddenly lock up while driving, it is recommended to hold the steering wheel tightly, let the car stop smoothly and then repair it in time.

Hello, this is a very dangerous malfunction. Pull over and find a rescue vehicle.

If you don't hit the brakes while driving and suddenly lock, then you have to beg God not to get into an accident, because you can't control the car.

If you step on the brakes to lock, you must immediately release the brakes, and carefully operate the steering wheel to stabilize the body, and then brake lightly, if the speed is not fast, you can test the gear to change the gear to low gear, if it is self-draining, immediately hit the low gear, and use the engine to slow down. Reduce the speed to less than 30 kilometers and then drive, gently pull the hand brake to slowly increase the force, and then press the brake to stop when the speed is slow. This way, the car will not deviate, and if you have a little time before you start doing these moves, remember to turn on your twin flashing lights, otherwise the car behind you is likely to hit you.

There is an opportunity to slowly drive the car to the side of the road during the operation.

If you suddenly brake and lock up while driving, it is best to pull over in time and find a trailer.

Hello, first check the braking system, the support rod of the brake master cylinder? Brake sub-cylinder, brake ABS pump.

In this case, you still need to control the steering wheel, otherwise the brakes will lock up, you will lose your balance, and accidents will easily occur.

Don't panic, hold the steering wheel steady and stop slowly.

Hold the steering wheel steady and apply the brakes intermittently!

If the electronic handbrake is locked, there are generally two possibilities, one is that there is a problem with the electronic handbrake system or a problem with the electronic handbrake actuator, resulting in the brake cannot be released. In this case, it is best to use the maintenance computer to detect it first, to see if there is any fault code, clear the fault code can not be recovered, you can remove the battery wire, stand for about 5-10 minutes, and then try it from the new installation, if there is no effect, then there may be a problem with the brake actuator.

If there is a problem with the brake actuator, one is that the internal locking mechanism cannot be unlocked, and the other is that the brake disc and brake pads and brake calipers are frozen together after the car is washed in winter.

If the problem of the actuator is not easy to solve, it needs to be disassembled and repaired, if it is frozen, boil a pot of boiling water and rinse it.

Hello, is the indicator light of the handbrake switch on? It is advisable to check the plugs of the fuse, handbrake switch and rear brake cylinder first. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】
