Will BMW G20 equipped with Savannah brake S67A shake? ( 1)

This incident originated from a fan in Chengdu. He bought a set of brake calipers of SAVANINI S67A in Tmall flagship store and installed them on BMW's latest G20 car. After less than a month, the reaction was shaking, so I contacted the manufacturer and the manufacturer changed two sets of brake discs for it, but it still didn't solve it.

Because the fans said that they bought Savannah after reading Gray's comments, Gray contacted the fans to coordinate with the manufacturer and got this set of brakes that were changed or shaken repeatedly.

The manufacturers are very cooperative. Zhang Factory hopes that we can help them find out the causes of jitter and optimize the compatibility of this brake with BMW G20.

As you can see, these two sets of disks are balancing the garage. We finally found a BMW G20 and plan to load it to test the jitter.

A clean caliper, a caliper that has been sent as it is.

The two sets of brake discs are different, and the wear of single mark and double mark is not very uniform.

Brake jitter may be a problem of matching the accuracy of joint bridge codes, uneven wear of brake discs and brake pads, or it may occur.

Let's feel the loading effect of CD single cross disk.

There are corrosion marks on the surface of a brake caliper.

There is no jitter in the initial test after getting on the bus, but it takes about 300 kilometers for the brakes to be fully opened and peeled. So we also entrusted the owner to record the real driving situation.

If there is jitter, we will also feed back the product problem to the manufacturer to optimize and solve the problem? Direction.

Thanks to the cooperation of the owners of BMW G20, they didn't buy it from us, but they still coordinated the manufacturers to give the fans a full refund and bear all the costs of testing.

This original intention, or nothing else, is just like trying to brake at our own expense. Whether a thing is good or not, we must know the reason. Since we have provoked this responsibility and won everyone's trust and support, we must work together.

This article is just the beginning, because it is a long period, so we are still waiting for the driver's driving feedback.

What is the reason? What about jitter? Waiting for our second "SAVANINI Brake Jitter Test".
