The First Step of Adjustment First, ensure that the original hub is compatible with the brake type, or both sides of the hub should be threaded. If not, it may not be easy to install. Then, try to install the disc brake seat and disc. Due to hub differences, the disc may be too close to the frame. This should be solved by adding shims on the shaft to increase the distance between the frame and the disc. You can also adjust the left and right distance through the shafts on both sides.

The Second Step of Adjustment Due to the poor concentricity of the discs installed on some bicycles, it is easier to scuff the brake pads when installing the brake caliper. Therefore, you have to adjust it yourself after installation. The pipe diameter installed on the conversion bracket may not be suitable for your car. If it is still too large, then you should find a gasket to pad it.
