If I press down the roller on the main stand at the rear, the front wheel can be rotated slightly or slightly heavier depending on the angle position. In addition, a clacker can be heard. Presumably: At least one of the brake discs has a side impact, takes the brake blocks with it to the top by friction and then drops them again when there is no friction. Now I measured the side impact once with a measuring clock. To the left it is about 0.2 millimeters, to the right about 0.1 millimeters . Is that still in the frame or too much? According to my understanding, the workshop manual does not specify the permissible side impact, there is only one of Excentricity, which is probably the height impact. In the forum already gives reports of warped brake discs. The MAXSYM has now 1000 km on the clock, inspection is pending. Greeting Karlchen
