About Brake 

First of all, the calipers are different in size and the horn data are different. There is no way to install them at all. Secondly, the caliper piston area of the original front wheel is large. Even if you rack your brains to install it on the rear wheel, the braking force will become larger, and the body may not be controlled during braking. If the rear wheel is not changed, it will not swing the tail. If it is changed arbitrarily, it will swing the tail


Calipers refitted. Can I just change the calipers? Do not change anything else?

No, the height, friction surface width and thickness of the original calipers are inconsistent with the data of our modified calipers.

You may not have a concept of the thickness of the original brake disc. Generally speaking, the thickness of many original rear wheel double-layer ventilation discs is about 22mm, while the minimum thickness of modified brake discs is 28mm, commonly 32mm and 36mm. If the thickness suddenly increases so much, the width of the original caliper may not be enough. It is simply understood that the mouth is too small to plug.


How often do you change the brake disc? Do you usually have the habit of maintaining the brake disc?

Many car owners will ignore the maintenance of brake discs. Today I'll tell you about this knowledge to let you know when to replace brake discs and the daily maintenance of brake discs.

How often do you change the brake disc?

How long the brake disc can be used mainly depends on people's road conditions, vehicle frequency and vehicle habits. So no one can say exactly how many years need to be replaced, because everyone is different. But there is also an estimated time. Generally, the brake pads need to be replaced after 30000-40000 km, and the brake discs need to be replaced after 70000 km. The service time of the brake pads is relatively short. Generally, the brake discs of the car are replaced after twice, and the rear brakes need to be replaced after 80000-100000 km. In fact, it can be judged how long the brake discs need to be replaced.

For today's cars, the models are different, and the brake discs on the car are also different. Moreover, many models do not have specific regulations on how many years or how many thousands of kilometers, but we should judge by the condition of the brake discs during the inspection. Many cars shake and make abnormal noises when the brake disc is not yet in service life. If one item is the sound of metal friction, be sure to check the brake disc and see if the brake disc has been worn to the point where the metal is exposed. This is the maximum limit of the brake disc, and it must be replaced at this time.

How to judge whether the brake disc needs to be replaced:

1. Listen to the sound. If the light braking is accompanied by the silky sound or roar of "iron rubbing iron" (it may also be the effect of running in of the brake pad at the beginning of installation), the brake pad must be replaced immediately. Because the limit marks on both sides of the brake pad have directly rubbed the brake disc, it proves that the brake pad has exceeded the limit.

In this case, when replacing the brake pad, cooperate with the inspection of the brake disc. When this sound occurs, the brake disc is often damaged and scratched. At this time, even if the new brake pad is replaced, the sound can not be eliminated. It is recommended to replace the brake disc in time. In addition, some brake pads with poor quality have hard spots, which will also produce abnormal noise. Generally, the abnormal noise will disappear after being worn off for a period of time.

2. Generally, whether the brake disc warning light on the instrument panel is on is used as the judgment basis for whether to replace the brake disc. Generally, the indicator light is off. When the brake disc is faulty or excessively worn, the light is on and off after repair. When the warning light is on, the brake disc has been worn to the limit, and the braking effect has decreased, which greatly affects the driving safety. Therefore, we suggest to regularly check the wear condition of the brake disc to see whether it can be used, rather than just trust the warning light.

3. Look at the thickness. Most brake disc products have wear indicators, that is, three small pits will be distributed on the disc surface. Measure the depth of the small pit with a vernier caliper, which is 1.5mm. In other words, the total wear depth on both sides of the brake disc reaches 3mm. In case of quasi wear and complete wear as shown in the figure below, we suggest replacing the brake disc in time. Of course, not all brake discs have wear indicators. We can use our fingers to touch the outer edge of the disc to judge the approximate depth. Generally speaking, if the total wear depth of both sides of the brake disc reaches 3mm, the brake disc should be replaced in time. In addition, when the brake discs (drums) on both sides use different brands and specifications, the friction effects are different, resulting in different braking effects on both sides, which will lead to the adverse consequences of brake deviation, poor braking effect and long braking distance. Therefore, it is recommended to replace the coaxial brake pads (shoes) on both sides at the same time to ensure the same braking effect.
