Does the car handbrake need maintenance How to check its sensitivity

Car handbrakes need to be maintained. The car has materials and can check the maintenance records of the car for free.

I believe that friends who often use cars know that as long as the car is parked during use, the handbrake will definitely be used. If the driver leaves the vehicle and does not use the handbrake, the vehicle may slide and cause an accident. However, the majority of riders must be reminded that in fact, the handbrake is not a universal insurance, because the effectiveness of the handbrake will slowly decline with the increase in the number of uses.

Sometimes, it is clear that the handbrake has been pulled, but the accident occurs because the brake system fails. Therefore, the majority of riders should regularly carry out proper maintenance and inspection of the handbrake of their car.

To check the sensitivity of the handbrake, you can use the following method: Drive slowly on a road surface without slopes, slowly pull the handbrake handle, and feel the sensitivity and engagement point of the handle. This inspection method may wear out the handbrake mechanism, so the number of inspections should not be too much.

During the inspection, if it is found that the braking efficiency or sensitivity of the handbrake is not ideal, it can usually be solved by adjusting the operating cable of the handbrake. There is an adjustable compensation mechanism at the junction between the bottom of the handbrake lever and the steel cable (generally covered by the interior parts), and the length of the brake cable can be stretched by loosening the lock nut with a wrench. However, the adjustment mechanism of some cars is located at the bottom of the car, and if it is inconvenient to adjust, it should be handled by professional maintenance personnel.

Hello, I can't see this myself, you need professionals and professional equipment.

Look at the type of handbrake Some need to be debugged.

<> "The handbrake usage rate of cars is very high, and maintenance is very important.

During the use of the car, the usage rate of the handbrake is very high. However, Handbrake is not a universal insurance, and its effectiveness will decrease with the number of uses. Many times, it is clear that the handbrake has been pulled, but it cannot play its due role due to system failure or improper use, resulting in accidents.

Please pay great attention to the majority of drivers, and should regularly carry out proper maintenance and inspection of the handbrake of your car.

Drive the car to a slope with a steep slope and a good road surface (preferably asphalt), press the brakes, put the gear in neutral gear (or hang in N gear if it is an automatic transmission), and pull the handbrake lever to the determined working point position. Then slowly release the brake pedal, if the car does not slip, it means that the handbrake is working well. In addition to braking effectiveness, the sensitivity of the handbrake should also be checked, which is especially important for hill starts.

Drive slowly on a road with no slopes, slowly pull the handbrake lever and feel the sensitivity and engagement point of the handle. This inspection method will wear out the handbrake mechanism, so the number of inspections should not be too much.

Many car owners think that when the braking system fails, they can pull the handbrake to slow down, but this practice is actually very dangerous.

Because the handbrake mechanism is not precise, the braking force on the left and right sides is unevenly distributed, and it is easy to lock the rear wheel of one side when pulling the handbrake at high speed, and the side slip occurs. The correct way to sell the cover is to slow down by downshifting, and only pull the handbrake to stop the car when the speed is very low.

Handbrake. If it is loose, it is recommended that you do not adjust it yourself, but go to the 4S store.

Or some other car repair shop to fix it. After all, you are not professional enough and do not have some professional tools, and you also have to think about your own safety and the safety of others. For specific operations, you can follow the following steps, for reference only:

1: Open the armrest box and remove the two fixing screws inside.

2: Loosen the handbrake wire fixing bolt to the loosest state.

3: Ignition in neutral, press the brake twice, and then you can see that the steel wire that was originally pulled out is withdrawn.

4: Turn off the heat. 5: Begin to tighten the handbrake wire fixing bolts, generally the bolts are exposed 1cm most sometimes start to try to pull the handbrake, I adjust the 5-6 gla death, this is a personal suggestion, this is the best distance I try to come down.

6: After adjustment, let go of the handbrake, light the brake and step on the brake more, turn off the engine and get out of the car to retreat to see, if there is no very laborious state, it means that the adjustment is very good, if it is very laborious to push, the handbrake adjustment is too tight, to loosen it, but it is recommended to follow the first method in the re-get.

Hope! Thank you.

Hello The handbrake is too tight for the vehicle, it is easy to wear the handbrake line, and the testing instrument has strict requirements for the performance of the vehicle during the detection, so the handbrake is loose, and you feel tighter than when the new car is adjusted.

Judge the tightness: park the vehicle on the flat road, release the handbrake, use the trolley, you can push, and the vehicle stops slowly after letting go proves that the handbrake is fine.

Generally, the handbrake is adjusted to 3 or 5 teeth, which is too tight and easy to cause brake pulling.

Hello, according to your description, it is recommended that you go to the repair shop for readjustment, I hope mine is helpful to you, hope, thank you.

Long-term parking gear.

1.Do not pull the handbrake all the way on.

The function of the handbrake is to let the vehicle not move or roll in a stable state, so as to achieve a stable state. However, it's not scientific that you have the handbrake full. Generally speaking, pulling to 70%-80% is enough!

If the tension is too tight, the handbrake cable will be deformed and the life will be shortened. If the pull is too tight, the return and reset ability of the handbrake cable will also decrease. The effect of the handbrake will also be weakened.

2.Pull the handbrake when stopping for a long time on a ramp.

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 can also prevent the P gear from locking the clamp from jamming the owner, causing the vehicle to be unable to move!

Under normal circumstances, when the handle is lifted to 70% of the whole stroke, the handbrake should be in the normal braking position, before detecting the braking force of the handbrake, you need to find this point, which can be determined by counting the ratchet sound, 70% of this position is the effective working point of the handle.

When detecting, drive the car to a slope with a large slope and good road conditions, step on the brake and hang into neutral gear (the automatic transmission is placed in N gear), pull the handle to the effective working point, and then slowly release the brake pedal, if the vehicle does not move, it means that the performance of the handbrake is good. In addition, it is necessary to check the sensitivity of the handbrake, you can drive slowly on a flat road, slowly lift the handle, feel the sensitivity and joint point of the handbrake, and the handbrake will be worn out while driving, so the number of detections should not be too much.

If the brake is found to be insensitive during testing, it can be solved by adjusting the handbrake cable, which has an adjustable compensation mechanism underneath the handbrake handle. When adjusting, you need to remove the decorative cover of the handle first, and then use the tool to adjust the length of the cable to ensure that the hand brake is in the best working condition.

Driving in a congested big city, during the morning and evening rush hours, the distance between the front and rear of the vehicle is basically less than one meter, and the slope of the overpass is very large, and both novices and veterans will slip. At this time, the parking brake is particularly important, which can be used to ensure that the car does not roll at the start and avoid accidents. However, few car owners will pay attention to check the hand brake, most of the vehicle's hand brake needs to be adjusted, the majority of car owners do not ignore the importance of hand brake, hand brake work is poor and needs to be adjusted in time.

Handbrake is important for every car owner. Situations such as handbrake failure will directly threaten people's safety. Here's how to detect and maintain the handbrake.

The handbrake handle, like the pedal of the footbrake, has a pull stroke. Normally, the handbrake system should be in the normal braking position when the handle is lifted to 70% of the full stroke. So before checking the braking force of the handbrake, you should first find out the 70% working point.

This operating point can be determined by calculating the ratchet. Park your car in a quiet place, slowly pull down the handbrake, and count the ratchet clicks until the handle is pulled all the way. The position of 70% of the total noise is then calculated, which is the effective operating point of the handbrake handle.

Drive the car to a slope with a steep slope and good road conditions (preferably asphalt), press the brakes, and put in neutral gear (if it is an automatic transmission, put on N gear). Pull the handbrake lever to the working point you just determined, then slowly release the brake pedal. If the car doesn't skid, the handbrake works well.

Because there is a gap in the brakes, sometimes the car will slide slightly after releasing the pedal, and then it will stop. As long as the sliding distance is small, the effect of the handbrake is normal. Do it once each uphill and downhill.

In addition to braking efficiency, the sensitivity of the handbrake should also be checked, which is especially important for hill starts. Drive slowly on a road surface with no slopes, slowly lift the handbrake handle, and feel the sensitivity and bonding points of the handle. This type of inspection will wear out the handbrake mechanism, so don't check too often.

In the above checks, if the braking function or sensitivity of the handbrake is found to be unsatisfactory, it can usually be solved by adjusting the operating cable of the handbrake. There is an adjustable compensation mechanism at the junction of the bottom of the handbrake lever with the copper cable (usually covered by the upholstery). Loosen the lock nut with a wrench to lengthen the length of the brake copper cable.

But some cars have an adjustment mechanism located under the car. If it is inconvenient to adjust, it should be handled by a professional maintenance personnel.

Many people think that if the brake system fails, they can pull down the handbrake to slow down. In fact, this is not right, because the handbrake mechanism is not accurate, and the braking force on the left and right sides is unevenly distributed. When driving at high speeds, pulling the handbrake can easily cause one of the rear wheels to lock up and slip, which is very dangerous.

The correct way to do this is to downshift and slow down, and then pull the handbrake to stop the car when the speed is very low.

In addition, some high-horsepower cars can still start with the handbrake working. If you accidentally drag the handbrake, the handbrake mechanism and brakes will wear out. As soon as you find the hand and foot brakes, you should check their functionality.

Spare tires and replacement tools such as jacks and nut wrenches should be prepared. Changing tires shouldn't be a difficult thing for men.

If the handbrake is adjusted too tightly, it is very bad for the vehicle and will easily wear out the handbrake cable. It can also cause the braking system to heat up, which is harmful to the entire wheel, causing excessive fuel consumption of the wheels, locking up when braking, and rapid tire wear. Of course, if the handbrake is loose, it is not good, and it will cause the situation of parking the car.

How to judge the tightness of the handbrake: If you do not pull the handbrake, you can push the car with your hand, and there is no problem with the handbrake.

The standard way to test the tightness of the handbrake is: park the car on a flat road, do not pull the handbrake, and then use the trolley, which can be pushed, and the car can stop slowly when letting go can prove that the handbrake is OK. Generally, some experienced people are slow down to count the "click" sound when they pull the handbrake, and the handbrake is generally adjusted when the third sound is adjusted.
