Hello to the world of screwdrivers! I drive an Aprilia SR Max 125 and would like to expand the rear wheel for the purpose of tyre change. Have so far everything that is in the way. Unfortunately, I fail at the distance of the brake caliper, because it cannot be pulled from the disc due to lack of space. The distance between the upper edge of the disc to the inside rim is simply too small. I have removed the saddle from the swing arm and from the adapter, but the space simply is not enough to pull off. I had even considered unscrewing the disc. But you can’t get the screw connection in the built-in condition… Question: Does anyone have a useful suggestion to remove the rear brake caliper??? Do you have to open it? If yes, how? What should I be aware of? Unfortunately I have not found any useful hints on the web or in the forum. I look forward to useful tips! Thank you!
