Yiziphi izinhlobo ze-brake fluid?
Okuqukethwe
Ngaphandle kwe-brake fluid, bekungeke kwenzeke ukumisa imoto ngokuphepha. Uketshezi lwamabhuleki luhamba ochungechungeni lwamapayipi amabhuleki nemigqa njengoketshezi olusebenza ngamanzi—uketshezi oluhamba endaweni evalekile ngaphansi kwengcindezi. Idlulisela ingcindezi ku-pedal yebhuleki kuma-brake caliper noma izigubhu ukuze imise imoto ukuthi inganyakazi.
I-brake fluid ibalulekile ohlelweni lokubhuleka futhi kufanele yenze umsebenzi wayo ezimeni ezinzima. Ngokusho kweNational Highway Traffic Safety Administration (NHTSA) yoMnyango Wezokuthutha, uketshezi lwamabhuleki kufanele luhlolwe ukuze luhlangabezane namazinga ayisisekelo angu-4:
- Hlala uketshezi emazingeni okushisa aphansi; akufanele iqine uma iqhwa.
- Imelana nokubilisa (kanye nokuhwamuka) emazingeni okushisa aphezulu.
- Sebenza nezinye izingxenye zesistimu yamabhuleki kanye nolunye uketshezi lwamabhuleki.
- Yehlisa ukugqwala kwesistimu yamabhuleki.
Ngemuva kokuhlolwa, wonke ama-brake fluids aqokiwe i-DOT (yoMnyango Wezokuthutha) kanye nenombolo emele indawo yokubilisa ephezulu. Izimoto eziningi eMelika zisebenzisa i-hygroscopic DOT 3 noma 4, okusho ukuthi zizomunca umswakama emoyeni. Ama-brake master cylinder tanks ngokuvamile awanalutho uma lokhu kuqala ukwenzeka. Akufanele zivulwe ngaphandle uma kunesidingo ngokuphelele ukuvimbela ukuwohloka ngaphambi kwesikhathi okubangelwa ukumuncwa ukushisa nomswakama. Nakuba lokhu kwenzeka ngokwemvelo lapho kubhuleka, ukusheshisa inqubo kwandisa ukwakheka kokugqwala kanye nemfucumfucu ohlelweni lwamabhuleki oludalwe uketshezi lwamabhuleki oluba ne-asidi.
Kunezinhlobo eziningana ezahlukene ze-brake fluid: i-DOT 3, i-DOT 4 ne-DOT 5, kanye nezigaba ezincane ezimbalwa. Ngokuvamile, lapho inombolo iphansi, iphoyinti elibilayo liyancipha.
IPHUZU 3
Uketshezi lwamabhuleki lwe-DOT 3 lusekelwe ku-glycol kanye nombala we-amber. Inephuzu lokubila eliphansi kakhulu elomile, okusho ukuthi iphoyinti lazo lokubilisa uma lisha, elihambisana nendawo yokubilisa emanzi kancane, noma izinga lokushisa uketshezi olubilayo lapho kubolile.
- Indawo yokubilisa: 401 degrees Fahrenheit
- Indawo yokubilisa eyehlisiwe: 284 degrees Fahrenheit
Ngenxa yokuthi i-DOT 3 i-hygroscopic, kufanele ishintshwe njalo ngemva kweminyaka embalwa ukuze ihlale isebenza.
IPHUZU 4
Abakhiqizi bezimoto base-Europe ikakhulukazi basebenzisa uketshezi lwamabhuleki lwe-DOT 4. Nakuba futhi lusekelwe ku-glycol, inendawo yokubilisa ephakeme ngenxa yezithako ze-borate ester ezinciphisa inani lama-asidi akhiwa lapho umswakama umuncwa. I-DOT 4 ivamise ukubiza imali ephindwe kabili kune-DOT 3 ukumboza amakhemikhali engeziwe. Benza kangcono kunoketshezi lwe-DOT 3 ezigabeni zokuqala, kodwa iphuzu labo lokubilisa lehla ngokushesha ezigabeni zakamuva.
- Indawo yokubilisa: Iqala ku-446 degrees Fahrenheit.
- Indawo yokubilisa eyehlisiwe: 311 degrees Fahrenheit
I-DOT 4 iya ngokuya isetshenziswa ekhaya, kodwa isalokhu ivame kakhulu ezimotweni zaseYurophu. Iza ngezigaba eziningana ezahlukene, njenge-DOT 4 Low Viscosity (ukunamathela) kanye ne-DOT 4 Racing - ngokuvamile eluhlaza okwesibhakabhaka esikhundleni se-amber. Nakuba ingaxutshwa ne-DOT 3, ngokuvamile kunenzuzo encane noma umehluko ekushintsheni.
IPHUZU 5
I-DOT 5 brake fluid isekelwe ku-silicone, imvamisa inombala onsomi ohlukile, futhi ibiza cishe ngokufana ne-DOT 4. Inendawo yokubilisa ephezulu futhi ayimumbi amanzi njengezinye izinhlobo ze-brake fluid. I-DOT 5 ayisebenzi kahle kwezinye izinhlelo zokubhuleka ngoba igwebu futhi idale amabhamuza omoya anikeza ukuzwakala kwebhuleki lesipontshi. Ngaphezu kwalokho, ngenxa yokuthi ayiwumumbi umswakama, noma iluphi uketshezi olungena ohlelweni luyigqwalile futhi lube nomthelela emakhazeni noma ekubiliseni emazingeni okushisa angemnandi.
- Indawo yokubilisa eyomile: 500 degrees Fahrenheit.
- Indawo yokubilisa emanzi: 356 degrees Fahrenheit.
Ngenxa yezakhiwo zayo ezihlukene, i-DOT 5 akufanele neze ixutshwe namanye ama-brake fluids. Yenzelwe izimoto ezigcinwa isikhathi eside, njengamasosha, futhi ezingasebenza ngokushesha lapho kudingeka. Naphezu kwendawo yokubilisa ephakeme kanye nezindawo zokulwa nokubola, uketshezi lwamabhuleki olusekelwe ku-silicone luyagwenywa abakhiqizi bezimoto ngenxa yokuncibilika okuphansi emoyeni nasemanzini.
IPHUZU 5.1
I-DOT 5.1 inendawo yokubilisa efanayo ne-DOT 4 racing fluids, isisekelo se-glycol kanye ne-amber ekhanyayo kuya kusikimu sombala okhanyayo. I-DOT 5.1 iwuketshezi lwebhuleki lwe-DOT 4 olususelwe ekwakhekeni kwekhemikhali ehlangabezana nezimfuneko ze-DOT 5.
- Indawo yokubilisa eyomile: 500 degrees Fahrenheit.
- Indawo yokubilisa emanzi: 356 degrees Fahrenheit.
Kungabiza ngokuphindwe ka-14 kune-DOT 3, kodwa ngokobuchwepheshe kuxubene kukho kokubili uketshezi lwe-DOT 3 no-DOT 4.
IPHUZU 2
Ayisetshenziswa kakhulu embonini yezimoto, i-DOT 2 brake fluid isekelwe kuwoyela wamaminerali futhi inamaphuzu abilayo aphansi amanzi futhi awomile. Ngokuyisisekelo, indawo yayo yokubilisa eyomile yindawo yokubilisa emanzi ye-DOT 5 kanye ne-DOT 5.1 yamabhuleki.
- Indawo yokubilisa eyomile: 374 degrees Fahrenheit.
- Indawo yokubilisa emanzi: 284 degrees Fahrenheit.
Iluphi uhlobo lwe-brake fluid okufanele lusetshenziswe?
Uketshezi lwamabhuleki oludala lungavala amasistimu ngenxa yokunqwabelana kokugqwala noma amadiphozithi futhi kuzodinga ukushintshwa ngezikhathi ezithile. Hlala ubheka izincomo zomkhiqizi wemoto yakho uma kuziwa ekukhetheni uketshezi lwamabhuleki. I-brake fluid kufanele futhi iguqe noma ishintshwe ngokuvumelana nezincomo zomenzi.
I-brake fluid kufanele iphathwe ngokucophelela. Ziyagqwala kakhulu futhi zizolimaza upende nokunye ukuqedwa uma kuchitheka. Ngaphezu kwalokho, zingaba yingozi uma zigwinywa, ngakho-ke ukuthintana nesikhumba noma amehlo kufanele kugwenywe. Lapho ushayela isistimu yamabhuleki, qiniseka ukuthi uketshezi lwamabhuleki olusha olusetshenzisiwe lugcinwe kahle nokuthi uketshezi oludala lulahlwa ngokuphepha. Umnikazi wemoto ojwayelekile uzodinga i-DOT 3, i-DOT 4, noma i-DOT 5.1 yemoto yakhe, kodwa ngaso sonke isikhathi uthembele kumininingwane yefekthri ukuze isistimu yakho yamabhuleki isebenze kahle.
