Why can t the handbrake be used for a long time while the vehicle is moving?

1. It is normal for this situation to occur, especially for novices who are easy to forget, but when the handbrake is not put down, you will feel that there is a resistance when you start the car, and when you start to walk up after starting, this resistance will be very small, and you should feel that there is a slight trembling, so you can check it. Of course, there is damage to the car, occasionally drive a few kilometers, nothing, for a long time, it will damage the brake pads to accelerate its wear, and the handbrake effect will decline when parking in the future, and the handbrake will be pulled very high to have an obvious braking effect, especially when parking on the slope, it is best to pay attention to the handbrake with the gear (generally hanging on the first gear) to prevent the car from walking the slope to avoid unnecessary damage.

2. The main brake of the car is the front brake, and the rear handbrake is only used when parking, therefore, it is necessary to develop a good starting operation essentials, hang neutral, step on the brakes, start the engine, release the handbrake, release the clutch slowly, and cooperate with the oil (the throttle should be given a little more when going uphill, and the oil should not be given when going downhill) Start smoothly and accelerate the gear. As long as you follow the same instructions every time, you should act quickly and not rush in case of emergency, which will reduce the low-level mistakes of forgetting to release the handbrake and hanging the wrong gear. For novices, they should be more strict with themselves, after all, the car's own hard-earned money should be cherished and used, and the car can better reflect a person's driving level than driving fast.

You can think about why the car is equipped with ABS anti-lock braking system.

The temperature of the rear brake disc is too high, emitting a burning smell, and the brake disc turns red in severe cases, and the rear brake thermal attenuation is serious, resulting in a decrease in braking performance.

It leads to the wear of the brake pads, shortens the service life of the brake pads, significantly improves fuel consumption, accelerates weakly, and has a sense of drag when the accelerator is released, resulting in eccentric wear of the tires. Even on the same vehicle, the braking ability of the four wheels is not exactly the same, so it can lead to uneven wear of the tires, increased brake fluid temperature, and reduced braking performance.

Handbrake precautions.

Many car owners park their vehicles on the ramp, and at this time they are also used to pulling the handbrake, which is really damaging to the handbrake. At this time, you can use some tools to resist the tires of the vehicle to prevent rolling, and the handbrake does not need to be so close. In addition, it can be controlled by placing the gear in 1st gear or reverse gear.

If your car has an electronic parking brake, be sure to pull the handbrake first and then put the gear in P mode. This prevents damage to the gearbox. It also prevents the P-stop locking clamp from getting stuck and making it impossible for the vehicle to move.

The above content refers to Encyclopedia - Handbrake.

Driving a car without releasing the handbrake results in intense wear and tear and rupture between the tire rubber and the ground, sparks between the tire and the ground, tire fire and spontaneous combustion, severe wear of brake pads, and broken brake lines. A car's hand brake is used to brake the rear wheels of a car. As long as the car handbrake is not pulled to the end, when the handbrake is pulled, the rear wheels of the car can still rotate, the car handbrake will not brake all the rear wheels of the car, and the car of the front-wheel drive model can still drive.

When driving with the handbrake for a long time, the most direct damage is the wear and tear of the handbrake. When driving with a handbrake, the pressure on the handbrake is not constant. It will change with the change in speed, through speed bumps and even collision with obstacles.

That is, during driving, the handbrake is constantly affected by large and small losses. It can even cause brake failure, smoke, and fire. If you use the handbrake for a long time, it may also cause the brake cylinder to jam, the brake fluid leakage and the brake fluid temperature is too high, resulting in the complete loss of the braking function, which is a dangerous thing for non-spike people.

If smoke is billowing out, the owner should brake immediately. When the handbrake is not lowered, you will feel resistance when starting the car. This resistance will be very small when you start walking.

There's nothing wrong with driving a few kilometers once in a while. Prolonged use will damage the rear brake pads and accelerate wear. In the future, when parking, the hand brake effect will decrease.

The hand brake should be pulled high to create a noticeable braking effect, especially when parking on a slope. It is best to use a handbrake with gears to prevent the vehicle from walking on slopes to avoid unnecessary damage. Formulate good starting operation essentials, shift into neutral, press the brake, start the engine, release the handbrake, slowly release the clutch, cooperate with the oil supply, start smoothly, and accelerate upshifting.

If you don't apply the brakes quickly, you'll forget to put the wrong gear in every time.

Driving with the handbrake has the most direct impact on the acceleration wear of the brake rock orange modification and the rough judgment that the brake pads become stiff after heating, and the handbrake cable is elongated. This will lead to a decrease in braking performance, and in severe cases, there will be smoke from the rear of the vehicle; If you pull the handbrake for a long time to drive, it may also lead to the brake cylinder biting, brake fluid leakage, brake fluid temperature is too high, and the brake function is completely lost. Generally speaking, when driving with a handbrake, the faster the speed, the greater the wear and tear of the brakes, and at the same time, it will also cause some damage to the tires.

It may cause the car to idle or cause the car to be affected by some influences, which will cause the car to stop, and it will also lead to damage to the car due to aging, and the brake pads will be worn, which will be affected.

It will tease the spine of the brake disc or damage the speed of the mountain, and the guide field will cause the handbrake line to be elongated, and the braking effect will be reduced. In severe cases, it will also cause smoke from the rear of the vehicle, and long-term driving will also cause spontaneous combustion of the vehicle.

It also depends on the situation if you don't use a handbrake for a long time to stop for a long time. For example, parking in places with small slopes requires a handbrake. If you stop at a place with a slope, the correct way to operate is as follows: N gear - release the foot brake (unload) - pull the handbrake - P gear - turn off the engine.

Due to the long-term shutdown to keep the steel wire tight, it is easy to cause irreversible plastic deformation of the steel wire, accelerate the aging of the steel wire, and reduce the service life. Especially when parking on the slope for a long time, if the steel wire is loose or broken, the car can easily slip on the slope, which is very dangerous. When parking, try to ensure that all parts of the car brake by hand and do not use force.

If you want to park the car on a slope for a long time, first pull the handbrake, put the "eye" (wedge) on the front and back of the wheel, wait for the wedge to be firmly pressed against the wheel, then release the handbrake, and finally put it in forward (or reverse). The step of "releasing the handbrake" is necessary to ensure that the parking force of the car is concentrated on the wedges and not on the gears or wires.

The handbrake is purely mechanical, and prolonged use reduces its effectiveness, and there is also a return spring that works in conjunction with the handbrake. When the handbrake is pulled, the spring is stretched; When the handbrake is released, the spring returns to its original length. When the handbrake is used for an extended period of time, the spring will deform accordingly.

When any component is used frequently over a long period of time, its utility decreases. But this does not mean "not used", but rather that the parts should be "used normally" according to their characteristics.

Parking for a long time without a handbrake also depends on the situation. For example, when parking in a place with a small slope, you need to pull the handbrake. If you stop in a place with a slope, the correct operation method is: hang N gear - release the foot brake (for unloading) - pull the handbrake - hang P gear - turn off.

Due to the long time of parking, the steel wire is in a taut state, which is easy to cause the plastic irreversible deformation of the steel wire, which accelerates the aging of the steel wire and reduces the life. Especially for long-term slope parking, if the steel wire is relaxed and broken, the car is prone to slippage, which is very dangerous. When parking, try to ensure that each part of the car is not forced, and the handbrake is braked.

If you want to park your car on a slope for a long time, you should first pull up the handbrake, put the "eye" (wedge) on the front and back of the wheel, and then release the handbrake after the wedge and the wheel are solid, and finally hang it in forward gear (or reverse). The "release of the handbrake" step is necessary to ensure that the stopping force of the car is concentrated on the wedges and not on the gears or wires.

The handbrake is purely mechanical, and long-term use will reduce the utility, and the handbrake is also used with the recovery spring. When the handbrake is pulled up, the spring is elongated; The handbrake is released, and the spring returns to its original length. When the handbrake is used for a long time, the spring will also deform accordingly.

When any part is used for a long time and frequently, there is a phenomenon of reduced utility. However, this does not mean "not to use", but rather to say that the characteristics of the part should be "used normally".

1. If the car is parked in the garage for a long time, the handbrake will be lifted up, and the brake will rust due to wet and other reasons. If you park in the open, you have to pull the handbrake so that the vehicle will not be pushed.

2. Theoretically, it is not suitable to use the handbrake for long-term parking, and long-term use will reduce the imitation guess and low performance.

3. If the parking time is more than 12 hours, it should be a long-term parking. This kind of parking makes the steel wire in a taut state for a long time, which is easy to cause the plastic irreparable deformation of the steel wire, accelerates the aging of the steel wire, and reduces the service life.

Consequences: 1. Running with the handbrake, the brake loss is large.

When driving with a handbrake, the most direct impact is that the brake disc accelerates and wears out, the brake pads become stiff after heating, and the handbrake cable is elongated. This can lead to a decrease in braking performance, and sometimes the smell of burnt smell is also caused by the owner, and in severe cases, there will be smoke from the rear of the car.

2. If the slope is congested, remember not to forget to pull the handbrake.

If you forget to pull the handbrake when you usually park, and the vehicle slips backwards, it may not be too dangerous to press the foot brake tightly. But if you encounter a traffic jam in the middle of a slope and the owner forgets to pull the handbrake, it is very dangerous.

3. At high speed, the handbrake cannot replace the foot brake.

Many car owners believe that in high-speed driving or sharp turns, in case of sudden crisis, you can directly pull the handbrake to slow down, and in an emergency, the handbrake can replace the foot brake, so that the car stops moving forward immediately. In fact, this practice is wrong and dangerous.

Emergency measures: 1. If you encounter driving with a handbrake while driving, and there is a serious burnt smell and smoke at the rear of the car, the owner should immediately slow down, brake, and put down the handbrake. At this time, do not continue to move forward, park the car on the side of the road, wait for the temperature of the car to cool down, and carefully observe if there is anything else.

2. Whenever the car is blocked in the middle of the slope and the phenomenon of slipping back, the first thing the owner should do is to be calm, not to panic, quickly step on the foot brake, let the car stop first, and then gently pull the handbrake. Slowly release and put the foot brake. At this time, it is best not to leave the foot brake, make sure that the hand brake is tightened, and then release the foot brake;

3. In high-speed driving, when you want to stop in an emergency, and the foot brake does not work, the first thing to do is to take a ride, release the accelerator, slow down by downshifting, and pull the handbrake to stop the car when the speed is slightly stable and the speed is significantly reduced.
