Njengoba ama-rotor amabhuleki enziwe ngensimbi, ayagqwala ngokwemvelo futhi lapho evezwe kumaminerali afana nosawoti, ukugqwala (i-oxidization) kuvame ukusheshisa.Lokhu kukushiya ne-rotor ebukeka kabi kakhulu.
Ngokwemvelo, izinkampani zaqala ukubheka izindlela zokunciphisa ukugqwala kwama-rotor.Enye indlela kwakuwukuthola ubuhlungu be-brake disc ukuvimbela ukugqwala.
Futhi ekusebenzeni okuphezulu, sicela uzothanda ama-rotor wesitayela abhoboziwe futhi afakwe.
