What is the cause of brake lag after changing the brake pads?

Fault phenomenon: when the driver releases the brake, the brake pedal is relaxed, but the wheel brake is still in the braking state in whole or part, and the brake cannot be quickly released. This will cause the brake drum (disc) to heat up and increase the driving resistance.

Cause of failure: The brake pedal has no free travel, and the brake pedal tie rod system cannot be returned.

The brake master cylinder return spring breaks or fails.

The oil return hole of the brake master cylinder is blocked by dirt, and the sealing ring is swollen or sticky and the pump body is stuck.

The tubing leading to the sub-pump is deflated or clogged.

The brake disc swing difference is too large.

The front brake seal was damaged, causing the piston to not return properly.

The sealing ring of the front and rear brake cylinders is swollen or sticky and the pump body is stuck.

Drum brakes: Broken or too soft shoe return springs.

Drum brakes, brake shoes, broken friction pads, or loose rivets.

Drum brakes: The brake drum is badly out of round.

This situation is not normal, do not open to see if you have dismantled the caliper, let alone dismantled the caliper, you need to check whether the exhaust is OK. If you haven't replaced the caliper, you have to see if your brake pads and brake discs are regular products New brake pads need to be run in with the brake disc, and it will be fine after a while, if there is still this situation, you need to change the brake fluid. Precautions for brakes:

1. Novices generally step on the brakes more, and the consumption will be larger. 2. Automatic transmission costs brake pads compared with manual transmission, because the shift of automatic transmission depends on the accelerator pedal and brake pedal. 3. The wear and tear of brake pads will be faster than that of cars on the highway.

Because the car that often drives in the city often has to stop and go, and the brakes will be used a lot. It may take dozens of kilometers to slow down or stop on the road, and there are relatively few opportunities to use the brakes. 4. Cars with large load capacity have large brake pad loss.

In the case of deceleration and braking at the same speed, the inertia of the heavy car is large, and the force of brake pad friction is large, so the wear is large. Generally speaking, in the case of mixed driving (half highway, half urban), the brake pads of the front wheels should last 6-70,000 kilometers. 5. The brake pads of the rear wheels should be used for more than 100,000 kilometers.

Of course, this is not absolute, but only an approximate average. The front brake pads wear out quickly, because when braking, the center of gravity of the car will lean forward, and the force to be borne by the front brake is greater than that of the rear brake, with a ratio of about 7:3

Therefore, the disc heel of the front brake is generally larger than that of the rear brake. @2019

<> "When should the brake pads be replaced:

1.When the brake pads are contaminated with oil or grease.

2.The brake pads make an unusual noise when braking.

3.When the wear alarm switch on the brake pad has been alarmed.

4.When the thickness of the brake pads is less than the minor repair standard allowed by the vehicle manufacturer.

In general, if the thickness difference between the two sides of the brake pads on the fixed brake caliper is reached, the thickness difference between the brake pads on the floating brake caliper needs to be replaced. However, it is not possible to accurately determine whether the brake pads are worn by simple external observation, so it is better to use a ruler to measure the thinness of the brake pads to see if they are within the allowable range.

The owner guesses that when purchasing brake pads, you should choose the brake pads of Youfan**, do not choose inferior brake pads, inferior brake pads due to the material is too hard or too soft, braking will wear the brake disc, and at the same time produce greater braking noise, the main thing is that the vehicle can not provide good braking power. In the case of continuous braking or high-speed emergency braking, the braking force declines more seriously, and the material on the surface will fall off the phenomenon of good hail, prolong the braking distance, and may even cause brake failure. So for the happiness and safety of you and your family, please choose ** brake pads to do for driving safety.

4.When the thickness of the brake pads is less than the minimum maintenance standard allowed by the vehicle manufacturer.

Under normal circumstances, if the thickness difference between the two sides of the brake pads on the fixed brake caliper is reached, the thickness difference between the brake pads on the floating brake caliper needs to be replaced when the thickness difference between the two sides of the brake pads is reached. However, it is not possible to accurately determine whether the brake pads are worn by simple external observation, so it is better to use a ruler to measure the thinnest part of the brake pads to see if they are within the allowable range.

When purchasing brake pads, the owner should choose the best protection of the brake pads, do not choose inferior brake pads, inferior brake pads due to the material is too hard or too soft, braking will wear the brake disc, while producing greater braking noise, the most important thing is that the vehicle can not provide good braking power. In the case of continuous braking or high-speed emergency braking, the braking force declines more seriously, and the material on the surface will fall off, prolonging the braking distance, and may even cause brake failure. Therefore, for the happiness and safety of you and your family, please choose ** brake pads to ensure driving safety.

The service life of brake pads is related to the specific conditions of the vehicle (urban roads, mountain roads, etc.), driving habits, vehicle weight, etc. Front-wheel drive vehicles have more braking force than rear brake pads, so they wear out relatively quickly. When the thickness of the brake pad is less than 7mm (including the thickness of the back plate) or the brake pad wear alarm, the brake pad should be replaced as soon as possible.

The harm of not replacing the brake pad in time: If it is not replaced in time, it will cause the steel plate of the brake pad to rub the brake disc and damage the brake disc, which not only increases the maintenance cost of replacing the brake disc, but also makes the braking distance longer, resulting in potential safety hazards. Overheating of the brake disc by the friction of the steel plate may also lead to brake failure, which seriously affects driving safety.

After replacing the new brake pads, it can ensure the best braking force and the normal operation of the ABS system during emergency braking, so as to ensure safe driving and avoid traffic accidents.

I hope you will adopt.

Because the brakes are not very effective, they are worn.

First, look at the thickness: the easiest way is to look at the tips of the dashboard, when the brake pad indicator is always on, you need to replace the brake pads in time, we can usually observe the thickness of the brake pads, so that we know it. Usually, a new pair of brake pads is about the thickness of the same, if your brake pads are less thick, you should consider replacing them.

Second: listen to the sound, if there is a slight sound of "iron rubbing iron" at the same time as the brake is tapped, it may also be the effect of the brake pads running in at the beginning of installation), at this time the brake pads must be replaced immediately. Because the limit markings on both sides of the brake pads have directly rubbed against the brake disc, it proves that the brake pads have exceeded the limit.

In this case, it is necessary to cooperate with the inspection of the brake disc while replacing the brake pads, and the brake disc has often been damaged when this sound occurs.

Third: step on the brakes by feeling, when the brake pads become thinner, our braking effect will be affected, at this time you need to step on the brake plate deeper to achieve the original braking effect, feel that the braking effect is significantly weakened, many people feel that their brakes have become softer, a little unstoppable, that prompts you to replace the brake pads in time, this method is relatively abstract, with a feeling may be a little difficult to grasp, so it is important to develop a good self-inspection habit. In addition, the reduction of braking effect will lead to an increase in brake fluid consumption, so it is important to check the condition of brake fluid when replacing brake pads.

Brake pads are also called brake pads. When motor vehicles and non-motorized vehicles [such as electric bicycles, human-powered bicycles, animal power vehicles, etc.] run and brake to a certain number of times and time, the brake pads are worn to the limit or close to the limit because of the brakes, in order to effectively brake and ensure driving safety, it is necessary to replace the brake pads that have been worn to the extreme in time.

The reasons for replacing the brake pads are as follows:

Brake pads are also brake pads, because brake pads are one of the important components of the braking system, which is very important to ensure the safety of vehicles. But brake pads are actually wearable parts.

The life of a brake pad is difficult to define in terms of a clear number of kilometers and time, as it depends on each individual's driving habits and driving conditions. However, usually the service life of brake pads is about 30,000 kilometers, and if used well, some can even reach 100,000 kilometers.

For the safety of yourself and others, the brake pads will wear out after a period of time, and after reaching a certain level of wear, you must replace the brake pads with new ones to ensure driving safety.

If you want to replace the brake pads, they must be the brake pads of the wheels of the car. The quality of the brake pads affects the safety of the car. Good brake pads will ensure that you can brake the car in time.

During the use of the vehicle, the brake pads will automatically wear out every time. When the brake pads are worn to a certain extent, the brake pads need to be replaced. Because after the brake pads are worn, it may cause the wheels to slip and not be able to brake the car.

It is also possible that the brake pads will rupture, causing the brakes to fail. These accidents will seriously affect your driving safety.

If you don't change, some abnormal noise when braking is still a trivial matter, the big thing is that this will greatly affect the braking performance of the vehicle, and it will also cause abnormal wear and tear of the brake disc, and the cost of replacing the brake disc if it is damaged can be much higher than the brake pads.

Because the car brake pads will wear and age after a long time, resulting in the weakening or failure of its braking effect, for the sake of driving safety, it needs to be checked and replaced regularly.

In fact, the brake is a system, with brake discs, brake pads, and an electronic program control system for brakes. In this system, the most susceptible to wear is the brake pads. For example, the brake pad is the eraser we used to write when we were children, and every time we step on the brake, it is equivalent to wiping it with an eraser, and slowly the eraser becomes shorter.

Brake pads are consumables, according to different models, there are regulations in maintenance, and some models stipulate that the automatic blades need to be replaced for 50,000 kilometers, otherwise there are potential safety hazards.

The brake is the safety guarantee of the vehicle, and if the brake pad is not replaced after serious wear, it will cause death.

The brake pads are worn out and do not meet the requirements for braking, in which case the brake pads must be replaced.

Because the brake pads are worn parts, they should be replaced regularly to ensure the operation of the braking effect and safety.

Brake pads will become thinner after a long time, affecting the braking effect and bringing danger, so they must be replaced.

Because of the long time, the brake pads wear out for a long time, and the braking effect is not good, of course, they must be replaced.

How do I change the brake pads? This is because your brakes are no longer working, and you have to break your brake pads, otherwise, you are prone to problems at that time.

The automatic pad will become soft after a long time, resulting in ineffective brakes, so it is necessary to replace the brake pads in time.

Replacing the brake pads is to prevent the brakes from failing, which is not a trivial matter, and there can be no mistakes.

Hello car owner, change a pair of such a good braking effect, and will not deviate from the brake, is for the braking effect.

When the vehicle's brakes fail or fail, the brake pads must be replaced.

Because for safety, the brake pads are brake pads, and the brakes are not good and prone to accidents.
