A sympathetic master. The brake caliper was unscrewed on the highway (before that, I went to a service station in Minsk complaining about a knock in the suspension (the brake caliper was unscrewed), nothing was found and all the silent blocks and ball bearings were sentenced, as a result, the brake caliper unscrewed to the end under the Lepel. Thanks to Google, I found and contacted this service station. The master did not refuse to help and search for the bolt and gave it to turn with his key. Thank you so much from Minsk!!!!
