Bophelo ba tšebeletso
Phetoho ea brake pad e itšetlehile ka hore na li-shims tsa hau li bile nako e kae bophelong ba koloi ea hau. Ka kakaretso, haeba u na le sebaka sa lik'hilomithara tse fetang 80,000, li-brake pads li hloka ho nkeloa sebaka. Leha ho le joalo, haeba u utloa lerata le hohla ho tloha mabiling a hao, ho sa tsotellehe hore na u na le lik'hilomithara life, u lokela ho nka sebaka sa li-brake pads. Haeba u sa tsebe hantle hore na u tsamaile lik'hilomithara tse kae, u ka ea lebenkeleng le nkang li-pads mahala, ua reka li-brake pads ho tsona kapa ua ea litšebeletsong tsa koloi ho li kenya.
Mokhoa oa ho hlokomela
1. Tlas'a maemo a tloaelehileng a ho khanna, hlahloba lieta tsa brake lik'hilomithara tse ling le tse ling tsa 5,000, eseng feela ho hlahloba botenya bo setseng, empa hape le ho hlahloba boemo ba ho roala lieta, hore na tekanyo ea ho apara mahlakoreng ka bobeli e tšoana, hore na ho khutla hoa tšoana. mahala, joalo-joalo, 'me ho fumaneha hore ha e ea tloaeleha Boemo bo tlameha ho sebetsanoa hang-hang.
2. Hangata seeta sa brake se entsoe ka likarolo tse peli: tšepe ea tšepe le thepa ea ho ferekana. Etsa bonnete ba hore u se ke ua emela hore lintho tse ferekaneng li fele pele u fetola seeta. Mohlala, seeta se ka pele sa brake sa Jetta se na le botenya bo bocha ba limilimithara tse 14, athe botenya bo boholo ba ho nchafatsa ke 7 mm, ho kenyelletsa le botenya ba lesela la tšepe le fetang 3 mm le botenya ba thepa ea likhohlano. hoo e ka bang 4 mm. Likoloi tse ling li na le alamo ea lieta tsa brake. Hang ha moeli oa ho roala o fihlile, meter e tla lla ho potlakela ho nkela seeta sebaka. Seeta se fihletseng moeli oa tšebeliso se tlameha ho nkeloa sebaka. Le haeba e ntse e ka sebelisoa ka nako e itseng, e tla fokotsa phello ea braking le ho ama polokeho ea ho khanna.
3. Ha u nkela sebaka, nka sebaka sa li-brake pads tse fanoeng ke likarolo tsa pele tsa lisebelisoa. Ke ka tsela ena feela phello ea braking pakeng tsa li-brake pads le brake disc e ka bang molemo ka ho fetisisa 'me ho senyeha hoa fokotseha.
4. Ha u nkela seeta sebaka, cylinder ea brake e tlameha ho khutlisetsoa morao ka sesebelisoa se khethehileng. Se ke oa sebelisa li-crowbars tse ling ho hatella morao ka thata, tse tla koba habonolo li-screws tsa brake caliper le ho etsa hore li-brake pads li khomarele.
5. Ka mor'a ho fetola, etsa bonnete ba hore u hatakela mariki ka makhetlo a 'maloa ho felisa lekhalo pakeng tsa seeta le brake disc, e leng se etsang hore ho se ke ha e-ba le brake leoto la pele, le atisang ho ba le likotsi.

Mokhoa oa ho fetola li-brake pads:
1. Tlosa brake ea letsoho, 'me u lokolle sekoti sa hub sa lebili le lokelang ho nkeloa sebaka (hlokomela hore e lokolohile, ha e sa soasoa ka ho feletseng). Tlisa koloi. Ebe u tlosa thaere. Pele o kenya mariki, ho molemo ho fafatsa tsamaiso ea brake ka mokelikeli o khethehileng oa ho hloekisa ho thibela phofshoana hore e se ke ea kena ka har'a phefumoloho le ho ama bophelo bo botle.
2. Hlakola brake caliper (bakeng sa likoloi tse ling, feela u lokolle e 'ngoe ea tsona, ebe u lokolla e 'ngoe)
3. Eketsa brake caliper ka thapo ho qoba ho senyeha ha peipi ea mariki. Ebe u tlosa li-brake pads tsa khale.
4. Sebelisa c-clamp ho sutumelletsa brake piston ho khutlela morao. (Ka kopo hlokomela hore pele ho mohato ona, phahamisa sekoahelo 'me u lokolle sekoahelo sa lebokose la brake fluid, hobane boemo ba mokelikeli oa brake fluid bo tla phahama ha piston ea brake e sutumetsoa holimo). Kenya li-brake pads tse ncha.
5. Kenya sekoahelo sa brake hape 'me u tiise screw ea caliper torque e hlokahalang. Busetsa thaere hape 'me u tiise li-hub screws hanyenyane.
6. Theola jack 'me u tiise ka ho feletseng li-screws tsa hub.
7. Hobane ha re ntse re fetola li-brake pads, re ile ra sutumetsa piston ea brake ka lehlakoreng le ka hare-hare, 'me e tla ba e se nang letho ha u qala ho hata brake. Ka mor'a mehato e 'maloa ka tatellano, ho tla ba hantle.
Mokhoa oa ho Hlahloba
1. Sheba botenya: Botenya ba "brake pad" e ncha hangata bo ka ba 1.5cm, 'me botenya bo tla fokotseha butle-butle ha ho ntse ho sebelisoa likhohlano. Ha botenya ba li-brake pads bo bonoa ka leihlo le hlobotseng, ho setse feela 1/3 ea botenya ba pele (hoo e ka bang 0.5cm). Mong'a lona o tla eketsa makhetlo a ho itlhahloba 'me a itokisetse ho e nkela sebaka ka nako leha e le efe. Mefuta e meng ha e na maemo a tlhahlobo ea pono ka lebaka la moralo oa hub ea mabili, 'me lithaere li hloka ho tlosoa hore li phethe.
Haeba e le ea morao-rao, ema ho fihlela lebone la temoso le khantšitsoe, 'me setsi sa tšepe sa brake pad le brake disc li se li le boemong ba ho sila ka tšepe. Ka nako ena, u tla bona litsupa tsa tšepe tse khanyang haufi le moeli oa rim.
