Shin na'urar firikwensin ciki tana gaba da baya ne
Firikwensin ABS yana hagu da dama. Firikwensin ABS muhimmin bangare ne na tsarin birki na hana kulle mota, wanda ake amfani da shi don gano saurin taya da aika shi zuwa sashin sarrafa ABS. Ta wannan hanyar, na'urar sarrafawa na iya daidaita girman ƙarfin birki bisa ga saurin da saurin tayar don hana kulle tayar. Yawanci ana sanya firikwensin ABS a wurare kusa da ƙafafun, wanda zai iya bambanta ta samfuri da alama. Ga samfura kamar Volkswagen Lavida, ana shigar da firikwensin ABS daban-daban bisa ga kowace ƙafa, jimilla huɗu gaba da baya hagu da dama. Wannan yana nufin cewa firikwensin ABS yana da maki hagu da dama a kan ƙafafun gaba na motar, don haka yana da mahimmanci a bambanta tsakanin hagu da dama. Misali, idan firikwensin ƙafafun baya na hagu ya lalace lokacin da kuka maye gurbin firikwensin ABS, kuna buƙatar maye gurbinsa daidai.
Don Allah a kira mu idan kuna buƙatar irin waɗannan kayayyaki.
