Ka thepa ea likhohlano, Calcined petroleum coke (PET Coke)e phetha karolo ea bohlokoa. Kaha PET coke e na le litšobotsi tsa boima bo tlase le porosity e phahameng, haholo-holo e bapala karolo ea ho fokotsa boima ba sehlahisoa, ho fokotsa lerata la braking le ho fokotsa ho bola ha mocheso oa thepa ea likhohlano ka mocheso o phahameng oa thepa ea braking.

Re ka fana ka sehlahisoa sa maemo a fapaneng, hape re thabela ho fana ka sehlahisoa se ikhethileng ho bareki ba rona ba tsoang lefats'eng lohle.
