The movement of the disc is regulated by inserting a shim,Prevents the disc from tilting too much into resistance during corners. adjusted so that the disc comes to the center of the caliper with a shim of 0.5 mm on the inside and 0.25 mm on the outside.
Also please put return spring inner diameter 0.5 ok, adjust the length by looking at the clearance.
