Ungashintsha kanjani i-brake fluid ku-BMW

I-braking system yemoto ngayinye idlala indima ebaluleke kakhulu, njengoba ikuvumela ukuthi uqinisekise ukusetshenziswa okuphephile kwemoto. Njengoba inqubo yokushintsha ilula, iningi labathandi bezimoto bancamela ukushintsha uketshezi lwamabhuleki ezimotweni zakwaBMW uqobo.

Izizathu zokushintsha uketshezi lwamabhuleki

Ukusebenza kwe-brake fluid kwenziwa ngemodi yokushisa ephezulu, ngezinye izikhathi ifinyelela kuma-degree angu-150 lapho ushayela endaweni yasemadolobheni. Lapho ushayela ngaphandle komgwaqo, ngaphezu kwemvelo yezemidlalo yokugibela, amazinga okushisa angakhuphuka nakakhulu, okufanele futhi kucatshangelwe.

Izinhlobo zanamuhla zimelana kalula namazinga okushisa angama-200 degrees. Baqala ukubilisa kuphela ngemva kokuba izinga lokushisa lifinyelele kuma-degree angu-200.

Ngokushintshwa okufika ngesikhathi, lolu lwazi luzobhekwa njengethiyori, kodwa ibha yokushisa izokwehla minyaka yonke, njengoba uketshezi lunempahla yokumunca umswakama omuhle kakhulu.

Lokhu kusho ukuthi umkhawulo obilayo phambi komswakama okungenani u-2% awusekho ama-degrees angu-250, kodwa ngu-140-150 kuphela. Uma ubilisa, ukubonakala kwama-bubbles emoyeni kubonakala, okuphazamisa ukusebenza kwesistimu ye-brake.

Isikhathi sokushintsha

Le parameter ilungiswa kuphela ngamamayela. Ngokuvamile, kufanelekile ukukhathazeka ngale nkinga kanye njalo eminyakeni engu-2-3, noma amakhilomitha ayizinkulungwane ezingu-40-50. Izimoto zakwaBMW zisebenzisa i-DOT4 grade brake fluid.

Ukushintsha i-brake fluid ku-BMW E70

Ngaphambi kokuqala umsebenzi, qiniseka ukuthi imiyalelo ejwayelekile yokusebenza yomshini iyalandelwa nokuthi i-baffle ye-heater iyasuswa.

Lapho wenza umsebenzi esikhundleni noma ukulungisa izingxenye ezilandelayo BMW E70, kufanele ulandele ngokuqinile imiyalelo yokusebenza:

•       I-Master brake cylinder;
•       Umfutholuketshezi block;
•       Izingxenye noma amashubhu axhuma kubo;
•       Iphampu yengcindezi ephezulu.

Ngemva kokwenza umsebenzi kokugcina, kuyadingeka kuphela ukopha i-wheel brake circuit phambi komshini. Ngaphambi kokudonsa isistimu yamabhuleki, kuyadingeka ukuthi uvule iphampu ye-boost kanye ngohlelo lolwazi lokuxilonga.

•       Ukuxhuma isistimu yolwazi lokuxilonga i-BMW;
•       Ukukhethwa komsebenzi okhethekile wokupompa umzimba we-valve;
•       Xhuma idivayisi ethangini ku-master cylinder bese uvula lonke uhlelo.

Ngesikhathi esifanayo, kuyadingeka ukuqinisekisa ukuthi imiyalelo yokusebenza komkhiqizi igcinwa ngokugcwele nokuthi izinga lokucindezela alidluli i-2 bar.

Ukupompa okugcwele

Ingxenye eyodwa yepayipi yehliselwa esitsheni ukuze ithole uketshezi, enye ixhunywe ekhanda elihlanganisayo esondweni elingemuva elingakwesokudla. Khona-ke okunamathiselwe kuyacishwa futhi idrayivu ye-hydraulic iphonswa kuze kuphume uketshezi, lapho kungekho khona amabhamuza omoya. Ngemuva kwalokho, i-accessory kufanele ivalwe. Umsebenzi uyaphindwa kuwo wonke amanye amasondo.

Amasondo angemuva

Ingxenye eyodwa ye-hose ixhunywe esitsheni sokwamukela, enye ifakwe ekufakweni kwe-clamp, emva kwalokho ukufakwa kukhishwe. Ngosizo lwesistimu yolwazi lokuxilonga, i-brake circuit iphonswa kuze kube yilapho amabhamuza omoya ephela. Izinto ezifakwayo ziyasongwa, futhi ukusebenza kuyaphindwa kwelinye isondo.

Amasondo angaphambili

Izinyathelo ezintathu zokuqala lapha zizofana nokumpompa amasondo angemuva. Kodwa ngemva kokupompa ngosizo lwesistimu yolwazi lokuxilonga, udinga ukucindezela i-pedal izikhathi ezi-5.

Akumele kube namabhamuza omoya oketshezini oluphumayo. Ngemuva kokuphinda ukusebenza kwesondo lesibili langaphambili, kuyadingeka ukunqamula isiguquli esitokisini, hlola izinga le-brake fluid bese uvala i-reservoir.

Ukushintsha i-brake fluid ku-BMW E90

Ukuze kwenziwe umsebenzi, imishini elandelayo izodingeka:

• Isikrufu senkanyezi sokususa i-valve yokudonsa;
• Ipayipi lepulasitiki elisobala elinobubanzi obungu-6 mm, kanye nesitsha lapho kuzophuma khona uketshezi lwamabhuleki olusetshenzisiwe;
• Cishe ilitha ye-brake fluid entsha.

Lapho usebenzisa i-brake fluid, imithethonqubo yokuphepha enqunyiwe kufanele igcinwe.

Ukukhethwa komoya ohlelweni lwe-BMW E90 kuvame ukuqhutshwa esiteshini sesevisi, kusetshenziswa idivayisi ekhethekile ewunikeza ohlelweni ngokucindezela kwe-2 bar. Lokhu kusebenza kungenziwa ngokuzimela, ngenxa yalokhu umsizi kufanele acindezele i-brake pedal izikhathi eziningana ukuze kukhishwe umoya owengeziwe ohlelweni.

Okokuqala udinga ukususa umoya ku-caliper yangemuva kwesokudla, bese usuka ngemuva kwesokunxele, kwesokudla ngaphambili nangaphambili kwesokunxele. Ngesikhathi somsebenzi, kuyadingeka ukuqinisekisa ukuthi umthamo woketshezi awehli ngaphansi kwezinga elidingekayo futhi ukhuphuke uma kunesidingo.

Ngemva kokuvala isivalo sethangi, hlola ukuqiniswa kwamapayipi ama-brake, ukuqina kokufakwa kwe-air outlet, kanye nokuqina (ngenjini isebenza).
