   Information 

   If the brake calliper cannot be removed easily, the brake pads must be pressed back slightly and evenly using a suitable tool (e.g. an assembly wedge) in order to get over the edge of the brake disc. To prevent damage, do not insert hard objects between the brake pad and brake disc! 

6. Carefully remove brake calliper.
