Product Description

Auto Brake Discs 390*34mm Slot Disc Floating Center For Audi RS4 B7


Brake Disc Material is Grey cast iron HT250. About 500 temperature. Can use for several years on the normal street

Split discs are used, one is the brake disc body, the other is the alloy center bell. The bell is made of alloy, and the color can be customized. I use black, and the bell can be used all the time. The next time the brake disc is replaced, only the brake disc body needs to be replaced, and the center bell does not need to be replaced; When the closing head and the brake disc body are locked together with screws, the dynamic balance inspection will be conducted again to prevent the dynamic balance from being affected and the brake jitter caused by the integration of the center bell and the brake disc body.



Attention must be paid to the direction of the disc. The function of the air guide groove is to dissipate heat. The working principle is that when the vehicle moves forward, the air guide groove constantly throws out the heat of the brake disc. Therefore, we must pay attention to the direction. It is to throw out, not to bump the wind in


The correct method of brake running in is when the brake is installed correctly. Accelerate the car to about 100km / h, then brake to 50km, then accelerate to 100km, and then slow down to 50km for 7 ~ 10 times. The running in can be completed. However, the newly modified brake must go through 500 ~ 1000 km running in to achieve the best state. In addition, remember not to use the method of violent sudden braking to open the disc for the new brake. This method is easy to carbonize the material of the brake pad. In addition, the braking performance of the newly installed braking system may be only 70% of that in the best state, so pay attention to the safe distance.


Jitter of the brake system: there are many reasons for the jitter of the brake system. One is that after intense braking, the brake disc flushes without cooling, resulting in the deformation of the brake disc. This situation is easy to occur in car washing. Therefore, after intense driving, we can't immediately flush the brake system with a faucet. We have to wait about 10 minutes for it to cool down. In another case, the dynamic balance data of the wheel hub is inaccurate, resulting in the shaking of the steering wheel when braking. This situation is most likely to be ignored. Generally speaking, the shaking of the car when accelerating is mostly related to the half axle. If the car slides without stepping on the accelerator, and the shaking of the steering wheel is mostly related to the dynamic balance of the rim. If the steering wheel shakes when braking, check the dynamic balance of the wheel hub and whether the brake disc is deformed. If the brake disc is deformed, The disc needs to be re polished, that is, the brake disc. It is also called brake disc dynamic balance, which is solved in this way
