Is it legal to modify brake calipers and is it legal to modify brakes for cars?

Modifying brake calipers is a change in the structure of the vehicle, which is an illegal act, and this behavior cannot pass the annual review.

According to the Road Traffic Safety Law of the People's Republic of China.

Article 16: No unit or individual may engage in any of the following acts:

1) Assembling a motor vehicle or changing the registered structure, structure or characteristics of a motor vehicle without authorization;

2) Change the motor vehicle model, engine number, and frame number.

or a vehicle identification number.

3) Forging, altering, or using a forged or altered motor vehicle registration certificate.

Number plates, driving licenses.

Inspection mark, insurance mark;

4) The use of other motor vehicle registration certificates, license plates, driving licenses, inspection marks, insurance marks.

Well, there is no problem, but only if the brake calipers are equipped with compliant** and the braking performance must exceed the specified set standards, otherwise it is considered an illegal modification. Secondly, you have to choose caliper modification instructions according to the model:

Add**. Leverage principle.

Tell us that the farther the caliper is away from the center of the disc, the more braking force is generated, and the less pedal force is required.

In addition to mechanical reasons, another important function of the brake disc is a large-area high-efficiency radiator, which is responsible for dispersing the heat energy generated during braking into the air, so from the perspective of pure performance, the larger the brake disc, the better.

There is one thing that must be introduced, the brake disc with **.

The area increases, the diameter increases, so the moment also increases, and there are two things:

First, the torque increases, and the braking performance increases by about 20%, which is pleasing to see;

Second, the area of the brake disc has increased, and the possibility of jitter has increased, and it often occurs, which may be due to the ejection speed of the single-piston caliper after replacing the **, and the bridge code added is not very suitable and will also cause after-sales problems such as jitter.

Here are some high-performance brake disc designs:

Although the cost of split brake discs is higher, it can reduce the weight of the disc;

The ventilation hollow design of the ventilator disc is to reduce and average the temperature of the inside and outside of the ventilator; The original brakes are set for daily driving, in Shanghai's Tianma Circuit, few cars with original brakes can run more than 5 laps in a row, and the braking force will drop significantly after brake heat exhaustion, and if you don't brake in advance, you will have the risk of rushing out of the track, and it will not be fun to rush out and hit the cement wall. So the second type of riders who modified the brakes appeared, small.

The scribing design on the friction surface helps to divert the brake chips generated during high temperature friction and prevent them from remaining between the brake pad and the brake disc, reducing the coefficient of friction.

Normally, it is legal to modify brake calipers, but only if they are equipped with compliant brake calipers and the braking performance must exceed the specified set standards, otherwise it is considered an illegal modification.

If the law does not prohibit it, it is legal from this point of view, and I did not see that the document clearly stated that the brakes could not be changed.

The law does not allow it, it is illegal from this point of view, and I have not seen that the document clearly says that the brakes can be changed.

However, the actual situation is that in the case of modification of the appearance and use of the vehicle, the traffic police have seized more.

As long as the braking force meets the requirements. Now the same is true, as long as the braking force requirements are met.

It is not illegal to modify the brakes. As long as you can pass the inspection.

No. The reason why the rear wheel can not change the caliper is that when the vehicle brakes it is easy to have the phenomenon of tail flicking, most of the car owners usually change the front wheel when they change the brake caliper. The calipers on the rear wheels are auxiliary brakes to prevent the rear wheels from swinging when the vehicle brakes urgently.

The original calipers of the rear wheels are enough to control the limbs without moving, and if Xinjing increases the braking force of the rear wheels, it will cause the vehicle to hug Tanner to death, triggering the intervention of the ABS anti-lock braking system. So, if the vehicle is only used for daily transportation, there is no need to modify the calipers on the rear wheels. Only by properly modifying the brake calipers can the car's braking ability be effectively improved.

Try not to change it, because if the rear wheel is modified with brake calipers, it is easy to rear-end collision while driving.

Haolong can not change the caliper or slip, because this is caused by the phenomenon of non-cautious Tuanling Kuanqi is often prone to tail flicking, and some of the effects are very bad, resulting in the vehicle locking.

Summary. Modified brake calipers are illegal modifications, and the traffic police will check and cannot pass the annual examination. Spraying calipers is generally fine, but replacing them is an illegal modification.

If it is not approved by the traffic police department, it is a private modification, or it involves vehicle safety data, which is an illegal act.

Modified brake calipers are illegal modifications, and the traffic police will check and cannot pass the annual examination. It's generally fine to spray the caliper late, but if you replace the caliper, it's an illegal modification. If Tan Lu suspects that it has not been approved by the traffic police department, it is a private modification, or it involves vehicle safety data, which is an illegal act.

Just took over the night shift, the car overturned on the road with continuous downhill turns.

At that time, no matter how much the brakes were pressed, it was not easy to use.

It's okay for me.

Afterwards, the owner said that the brakes that had just been changed were easy for others to use, so why did you say that they were not easy to use.

The above is Zheng prohibited, China's law stipulates that there are relevant regulations for large cars, and the braking system of Ling Zhen is not mentioned in private cars. Since it is not mentioned, that is, it can be done, "For private rights, the law does not prohibit it; For public power, the law does not prohibit "for our private foot posture car, it is okay to modify the brakes, and it does not constitute a violation, and the modification of large cars should be hidden, only the traffic police do not check."
