 Damage occurred to the launch cable which was frayed and required replacement , to the engine including minor damage to seals , and to many of the brake fins . The brake fins in the launch section are mounted to keep fast @-@ moving trains from moving backward into the station . However , the fast @-@ moving train being pulled forward caused an unexpected stress on a number of fins bending them forward . Not all required replacement , but there were more damaged brake fins than Six Flags had replacements for . Extra brake fins had to be ordered from the manufacturer , Intamin in Switzerland , and the ride had to undergo thorough testing following the repair . Kingda Ka reopened on August 4 .
