Kev tuav lub nruas nres hauv ob sab phlu yog ib feem tseem ceeb ntawm kev nyab xeeb ntawm lub tsheb thiab lub neej ntev. Tsis zoo li disc nres, lawv raug kaw, yog li kev tshuaj xyuas yuav tsum ua haujlwm me ntsis ntxiv.
Nov yog cov lus qhia ntxaws txog yuav ua li cas tswj koj lub nruas nres hauv ob sab phlu, los ntawm cov tshev yooj yim mus rau qhov kev pabcuam tag nrho.
Ntu 1: Nkag siab cov cim ntawm Hnav
Ua ntej, paub thaum twg koj tus brakes yuav xav tau kev saib xyuas. Cov tsos mob tshwm sim muaj xws li:
- Scraping los yog sib tsoo suab nrov:Lub suab nrov ntawm hlau- ntawm- hlau feem ntau txhais tau hais tias cov ntaub hauv ob sab phlu tag nrho thiab cov khau yog sib tsoo tawm ntawm lub nruas.
- Tsheb rub mus rau ib sab:Thaum braking, qhov no tuaj yeem qhia tau tias muaj kab mob (xws li, nrog cov dej nres) lossis cov ntaub npog ntawm ib sab.
- Tsawg Nres Pedal:Lub pedal mus ze rau hauv pem teb ua ntej koom. Qhov no tuaj yeem yog vim cov ntaub qhwv los yog xav tau kev hloov kho.
- "Nyem" lossis Tus Kheej -Adjuster Noise:Tej zaum koj yuav hnov ib "nias" thaum thim rov qab thiab nres, uas feem ntau yog tus kheej -kho lub tshuab ua haujlwm.
- Nres Nres Nres Feels Loose:Yog tias qhov chaw nres tsheb nres tsheb mus deb dhau lawm, lub tsheb nres tsheb yuav raug hnav lossis tsis hloov kho.
Ntu 2: Kev Ntsuam Xyuas Kev Pom Kev (Cov kauj ruam tseem ceeb tshaj plaws)
Koj tsis tuaj yeem kuaj xyuas lub nruas nres yam tsis tau tshem lub nruas. Qhov no yog qhov ua tau zoo tshaj plaws thaum lub log tsheb tig los yog ua ib feem ntawm qhov kev pabcuam tau teem tseg.
Yam koj yuav xav tau:
- Jack thiab Jack Stands
- Lug Wrench
- Hnab looj tes & looj tsom iav
- Ib lub taub hau ntsia hlau los yog ib lub cuab yeej hloov kho tshwj xeeb (feem ntau diav)
Txheej txheem:
1.Safely nqa lub tsheb:Ruaj ntseg lub tsheb ntawm jack stands.Tsis txhob ua haujlwm hauv lub tsheb tsuas yog txhawb nqa los ntawm lub jack.
2. Tshem lub log:Tshem cov txiv ntoo thiab lub log kom nthuav tawm lub nruas nres.
3. Tshem lub nruas nres:Lub nruas yuav tsum swb. Yog tias nws daig, nws yuav raug tuav los ntawm daim di ncauj xeb lossis cov khau khiab khau khiab tawm tsam nws.
Yog daig:Xyuas kom lub nres nres nres yog tso tawm tag nrho. Coj mus rhaub ib ncig ntawm lub nruas nrog roj hmab mallet. Tej zaum kuj yuav muaj threaded qhov nyob rau hauv lub nruas; screwing bolts rau hauv cov no yuav thawb lub nruas tawm.
4.Nrhiav cov Linings (Brake khau):
- Sab hauv Thickness:Txheeb xyuas qhov tuab ntawm cov khoom sib txhuam.Yog hais tias lub hauv ob sab phlu yog 1/8 nti (3.2 mm) los yog tsawg dua ntawm nws qhov thinnest point, nws yuav tsum tau hloov.Qee nkawm khau muaj qhov taw qhia hnav; yog tias nws ploj mus, lawv hnav tawm.
- Kev kis kab mob:Nrhiav glazing ( ci iab, tawv tawv), roj, los yog cov dej nres ntawm lub hauv ob sab phlu. Cov kab mob uas muaj kab mob tsis tuaj yeem tuav tau zoo thiab yuav tsum tau hloov. Lub hauv paus ntawm cov xau (piv txwv li, lub tog raj kheej log) yuav tsum tau kho.
- Kev puas tsuaj los yog tawg:Xyuas seb puas muaj kab nrib pleb hauv ob sab phlu lossis khau nws tus kheej.
- Txawm hnav:Cov hauv ob sab phlu yuav tsum hnav sib npaug ntawm nws qhov chaw. Kev hnav tsis sib xws tuaj yeem qhia tau tias muaj teeb meem nrog lub tog raj kheej lub tog raj kheej, hloov kho, lossis kho vajtse.
Ntu 3: Kev Tu thiab Lubrication (Lub Ntsiab Rau Lub Neej Ntev)
Plua plav thiab khib nyiab yog cov yeeb ncuab ntawm lub nruas nres. Thaum twg koj muaj lub nruas tawm, kev ntxuav yog qhov tseem ceeb.
1. Hnav daim npog qhov ncauj!Nres plua plav yog ua pa phem.
2.Clean nrog Brake Cleaner:Use a dedicated aerosol brake cleaner to thoroughly spray down the backing plate, all the hardware (springs, levers), and the inside of the drum itself. Tsis txhob siv cov cua compressed, vim nws yuav tsim kom muaj huab cua phem.
3.Lubricate Contact Points:Qhov no yog ib kauj ruam tseem ceeb los tiv thaiv lub suab nrov thiab ua kom muaj kev ua haujlwm zoo.
- Siv lub siab -cov roj roj kub lossis cov roj hluavtaws hluavtaws rau cov ntsiab lus uas cov khau nres tiv thaiv lub phaj rov qab (cov ntaub qhwv los yog "ledges").
- Maj mam lubricate cov xov ntawm tus kheej -adjuster mechanism.
- Lubricate cov ntsiab lus qhov chaw nres tsheb nres cable thiab lever pivot.
- TSEEM CEEB: Khaws cov roj kom deb ntawm cov hlua khi thiab lub nruas qhov sib txhuam.
Ntu 4: Kev Kho Kom Zoo
Nruas brakes muaj tus kheej - kho mechanism uas feem ntau activates thaum koj thim rov qab thiab nres. Txawm li cas los xij, cov no tuaj yeem ua tsis tau lossis txeeb tau, ua rau lub pedal qis.
Yuav ua li cas Manually Kho:
- Nrog lub nruas tawm, nrhiav lub hnub qub - log adjuster (nws zoo li lub iav los yog lub hnub qub).
- Tig lub hnub qub- lub log nrog koj lub cuab yeej hloov kho lub taub hau lossis lub taub hau taub hau.
Rule of Thumb:Tig lub hnub qub- lub log kom cov khau txavsab nraud. Koj tuaj yeem nco qab qhov no los ntawm: "Tau rau ntawm lub hnub qub- lub log kom nthuav dav, nqes mus rau kev cog lus." (Kev taw qhia tuaj yeem sib txawv ntawm lub tsheb, yog li saib cov khau).
- Qhov tseeb Fit:Re-nruab lub nruas. Qhov kev hloov kho kom raug yog thaum koj tuaj yeem nyuam qhuav swb lub nruas ntawm cov khau, thiab nws tig dawb nrog me ntsis luag. Yog hais tias nws yog ib qho nyuaj rau mus los yog yuav tsis tig, rov qab tus adjuster tawm ob peb clicks.
Ntu 5: Thaum Yuav Hloov
Hloov cov hlua khau (khau) yog tias:
- Lawv nyob ntawm lossis qis dua qhov tsawg kawg nkaus thickness.
- Lawv kis tau nrog cov roj los yog cov kua nres.
- Lawv tawg, tawg, lossis puas.
Qhov Zoo Tshaj Plaws: Hloov hauv cov axles.Ib txwm hloov cov khau khiab ntawm ob sab laug thiab sab xis ntawm tib lub qag tib lub sijhawm, txawm tias tsuas yog hnav ib sab. Qhov no ua kom muaj kev sib txhuam braking.
Thaum hloov cov khau, nws raug pom zoo kom hloov cov khaukho vajtse kit(caij nplooj ntoos hlav thiab khaws cia) thiab kom muaj lub nruas nresrov tshwm sim(machined smooth) ntawm lub khw muag khoom tsheb kom paub meej tias qhov chaw tshiab, tiaj tus rau cov khau tshiab rau txaj tawm tsam.
Summary: Lub Sijhawm Saib Xyuas
- Txhua 6-12 lub hlis / Lub Sijhawm Tire Rotation:Visually soj ntsuam cov brakes los ntawm tshem cov nruas. Txheeb xyuas cov kab tuab, saib kom muaj kab mob, thiab xyuas cov khoom siv kho vajtse.
- Nyob rau txhua qhov kev tshuaj xyuas:Tshem tawm cov plua plav nres nrog nres nres thiab lubricate cov ntsiab lus sib cuag.
- Raws li xav tau:manually kho tus brakes yog tias koj ntsib tus pedal qis thiab tus kheej -adjusters tsis ua haujlwm.
- Thaum hnav los yog puas:Hloov cov khau khau, kho vajtse, thiab kom cov nruas rov ua dua.
Tsis lees paub:Nres yog qhov tseem ceeb ntawm kev nyab xeeb. Yog tias koj tsis ntseeg koj lub peev xwm los ua cov haujlwm tu vaj tse, thov ua haujlwm los ntawm tus kws kho tsheb tsim nyog.
