Zvimwe zvikamu zvemotokari hazvigoni kuita pasina mhepo, asi zvimwe zvinotokuvadza. Kupinda kwemhepo, ndiko kuti, kuvapo kwemhepo isingadiwi, inozviratidza nenzira dzakasiyana.
Mune iyo hydraulic brake system, inozviratidza se "kudonha" kwepedal pasi pekumanikidzwa kwetsoka, pasina kutaurwa mhedzisiro. 
braking effects. Paunodzvanya brake pedal munhevedzano, inotanga kusimuka uye panguva imwechete kushanda kwebhureki kunowedzera. Iyo hydraulic clutch control system inobata zvakafanana nemhepo ingress. Mushure mekutsikirira pedal, iyo clutch haina kuregedza zvizere, izvo zvinoita kuti zviome kana zvisingakwanisi kushandura magiya. Iyo clutch inogona kungobviswa zvizere mushure mekudzokororwa nekukurumidza kuora mwoyo kweiyo pedal. Chikonzero chemhepo inopinda mu hydraulic brake uye clutch system inowanzova nzira isina kururama yekubuda ropa mushure mekugadzirisa, kusakwana kwemvura mumudziyo, kana kudonha kuduku.
Kuenzaniswa nema hydraulic system, kuona mhepo muinjini yekutonhodza system kwakaoma zvakanyanya. Mumamiriro ezvinhu aya, motokari inowanzopisa, izvo zvinogona kukonzerwa nezvimwe zvikonzero. Muchiitiko chekuvapo kwemhepo mumhepo inotonhora, kuderera kwesimba rekupisa kunoonekwa zvakare, asi izvi zvinogonawo kuva mugumisiro wekukanganisa kwakasiyana-siyana. Mhepo iri muhurongwa hwekutonhodza inowanzoitika nekuda kwekudonhedza iyo mvura inokwanisa kunyura kune rumwe rutivi, uye kune rumwe rutivi, kana iyo system yatonhora pasi, mweya unogona kuyamwa mukati kubva kunze, uye kudzvanywa kunoburitswa muinotonhora system. . Mhepo mumhepo yekutonhodza ndiyowo mugumisiro wekubuda ropa kusina kunaka mushure mekugadzirisa. Mamwe masisitimu anogona kupinza mweya, mamwe haaite uye anoda mamwe zviito kuita izvi. Kusaziva kwavari kana nzira shoma dzekupomba dzinotungamira kune chokwadi chekuti haisi mhepo yese inobviswa kubva muhurongwa.
Diesel mafuta jekiseni masisitimu anonzwa zvakanyanya kumhepo ingress. Kuvapo kwemhepo mumafuta edhiziri kunogona kukanganisa kushanda kweinjini. Nzira yekubuda ropa inonyatsotsanangurwa nemugadziri. Kana pasina mirairo yakadaro, mutemo wechigunwe unofanira kunge uri kuburitsa ropa rehuni yekutanga uye ipapo mudziyo wejekiseni.
