Ngingayihlola kanjani ama-brake pads ngami?
Izikhala zokubamba ziya zishwabana ngokusetshenziswa, zandisa ibanga lokumisa futhi zifaka engozini yokulimala kwe-rotor uma zinganakiwe. Ukuhlola isimo sezikhala njalo kungavimbela ukulungiswa okudlula izindleko. Le mhlahlandlela ibheka amathuluzi, ukuphepha, nezindlela zokuhlola ezinyathelweni – kokubili ukuhlola okusheshayo ngokusebenzisa isondo nokuhlola okuningiliziwe lapho isondo sikhishwe – kanye nokuthi ungakmeasure kanjani ubukhulu bezikhala, izimpawu zokugqoka okufanele uzinakekele, nezikhathi zokuhlola eziphakanyisiwe.
Izinsiza Eziphumelelayo
- Ukwenza ngaphandle kokususa amavolumu:
A bright flashlight or work light, and a small mirror (or phone camera) to see behind the caliper if needed. A ruler or brake-pad gauge (feelertype or caliper tool) helps measure thickness.
In addition, you will need a lug wrench or impact gun to loosen lug nuts, a floor jack and jack stands, and possibly a torx/Allen socket if your vehicle has hubcaps. (Optional: a popsicle stick or wooden dowel can be used as a simple gauge.)
- Personal safety gear: 个人安全装备:
Gloves and safety glasses to protect from brake dust and debris. A mask is advisable if cleaning dust. Also keep a set of wheel chocks to secure the vehicle during any lifting.
Ukuphepha Izinyathelo
Park op 'n vlak oppervlak, aktiveer die parkeerrem, en blokkeer ten minste een agterwiel voordat jy optel. Moet nooit net op 'n jack staatmaak nie – ondersteun altyd die motor op behoorlik gegradeerde jack staan voordat jy onder of naby die wiele werk.
- Cool brakes before touching:
Brakes can become extremely hot after driving. Allow them to cool to avoid burns. When hot, do not touch rotors or pads (they’re very hot!) as noted in the warning.
Xhoma izigqoko nezivikelo zamehlo. Ibhreyki dust ingaba ne-asbestos noma ezinye izinto eziphazamisayo, ngakho qaphela ukungayiphumuli emoyeni. Sebenzisa indwangu ethambile noma um cleaner we-brake ukuze ucoce izingxenye uma kudingeka. Qinisekisa ukuhamba komoya okwanele uma ungaphakathi.
- Sebenzisa amathuluzi afanele:
Sikuti izinqubo ezifanele (ukukhulula ama-lug nuts kuphela uma amavhiki ethinta umhlaba, njll.). Uma ungazi, xhumana ne-manual yokusebenza. Ngaso sonke isikhathi susa izinsimbi zokuhlobisa futhi uqinisekise ukuthi izingubo ezikhululekile ziqinile ukuze ugweme ukuhlinzeka ezicini ezihambayo.
Quick Inspection (Wheel On, Exposed Calipers)
Figure: Many alloy/spoked wheels expose the brake caliper and pad. A flashlight or mirror can be used to inspect through the wheel’s openings.
- Bheka phakathi kwezikhala zomjikelezo:
Some cars have wheels or hubcaps that let you see the brake rotor and outer pad without removing the wheel. If your wheels have large openings (or if you remove the wheel center cap), shine a flashlight onto the inside of the wheel.
- Check pad thickness: መለኪያ የፓድ ወርድ ይመልከቱ:
Compare the visible pad’s friction material to its metal backing plate. If the friction part is very thin – for example, less than about 1/4 inch (6 mm) – the pads are worn and should be replaced. A simple rule is: if the pad material is as thin as (or thinner than) the backing plate, it’s time for new pads.
Visible deep grooves or scoring on the rotor often mean the pads have worn into the disc. Blue or discolored spots on the rotor indicate overheating. These signs suggest pads (and possibly the rotor) need service.
- Lalela ngezinkomba zokugqoka:
Many pads have built-in metal tabs that squeal when the pad wears low. If you hear a high-pitched squeal during braking (which stops when the brakes are applied), it means the pads are nearly worn through. Some vehicles also have electronic wear sensors; if the sensor is visible and touching (or nearly touching) the rotor, replace the pads.
- Use a gauge or stick (optional):
If you can get a straight object (wood stick, screw, or gauge) next to the pad, you can estimate thickness. For example, slide a popsicle stick between the rotor and pad backing and mark the stick at the pad’s outer face. Then measure from that mark to the end of the backing plate – it should be several millimeters. (If only ~3–5 mm of pad material remains beyond the backing, replacement is likely overdue.)

With the wheel off you can see and feel both pads on the caliper. Look at the friction material (the part that presses against the rotor). If it looks very thin (on either side), replacement is needed. As a rule, if either pad is less than about 3–4 mm thick, plan to replace both pads.
- Bheka ukugqoka okungalingani:
The inner and outer pads should wear roughly the same. If one pad is much thinner, the caliper may be binding or sticking. Uneven wear can cause the car to pull to one side under braking. (In that case, the caliper or slide pins may need servicing.)
Bheka ubuso be-rotor ukuze ubone imifantu emikhulu, ama-crack, ukuguquka noma ukugqwala. Imigqa emincane iyajwayeleka, kodwa imigqa emikhulu ibonisa ukuthi ama-pads afaka impahla ku-rotor. Imigqa eluhlaza noma umbala wegolide emetalini ye-rotor ibonisa ukushisa okukhulu. Uma i-rotor ibonakala ibhujiswe kakhulu noma iguqukile, ingase idinge ukujova kabusha noma ukufakwa esikhundleni uma ushintsha ama-pads.
- Inspect caliper and hardware:
Bheka ukuthi i-caliper ihamba kahle eziphinini zayo. Hlanza futhi ufake uwoyela eziphinini zokuhamba uma zikhanda. Qinisekisa ukuthi ama-clips, ama-shims, kanye nephedi ye-steel backing plate ayingxenye ayiphukile noma ayiphukile. Futhi uqinisekise ukuthi akukho msebenzi we-brake fluid o leaking.
Measuring Brake Pad Thickness
Figure: Ukulinganisa ubukhulu bepad ngokusebenzisa ukuvuleka kwe-caliper. Susa umgibeli noma i-brake gauge ngokumelene nepad ukuze ufunde ubukhulu bemathiriyeli.
- Shandisa chishandiso chekuyera:
Ukuze uqinisekise ukuthi uhlole kahle, sebenzisa i-caliper noma i-feeler gauge. Faka ithuluzi emnyango we-caliper ukuze uthinte ubuso bepad. Funda ubukhulu kuphela bemathiriyeli yokucindezela (ungabali ipuleti lesikhumba lesinyathelo).
Brand-new pads are typically around 10–12 mm thick. Most manufacturers recommend replacing pads by the time the friction material is only ~3 mm (about 1/8 inch) thick. In practice, many mechanics advise replacing when pads reach about 3–4 mm.
If you don’t have a tool, a marked stick can serve as a gauge. For example, press a flat screwdriver or stick against the rotor and make a mark at the pad surface. Then measure from that mark to the back of the pad. Subtract the backing-plate thickness to estimate the friction depth. If only a few millimeters of material remain, replace the pads.
Khumbula ukukala noma ukulinganisa kokubili ama-pad angaphakathi nangaphandle. Udinga ukukala okukodwa kuphela uma kubonakala kufana, kodwa uma i-pad eyodwa incane, ukukala leyo. Noma kunjalo, ama-pad e-brake kufanele ashintshwe ngama-axle-set (kokubili ama-pad angaphambili noma kokubili ama-pad angemuva ndawonye) ukuze kube nokumisa okufanayo.
Signs of Brake Pad Wear or Damage
A squeal or chirp when applying the brakes usually means the wear indicator tab is contacting the rotor. A grinding noise means the pad material is gone and the metal backing plate is grinding on the rotor – a critical sign pads must be changed immediately.
If stopping distance increases, the pedal feels spongy or goes lower than usual, or you need to press harder to brake, the pads may be thin. (Air in brake lines or low fluid can also cause these symptoms, but worn pads are a common culprit.)

Visually, any pad with less than ~6 mm of friction (about ¼ inch) should be replaced soon. Some pads have painted edges or slots that serve as visual gauges; once the friction layer is nearly even with those features, it’s time for new pads.
- Rotor condition: Rotor yaka
Deep grooves, cracks, or rust on the rotor surface suggest damage. Rotors glazed to a shiny finish can also reduce braking, and bluing means overheating. All these point to worn pads or other brake issues.
- Brake pad deposits: መታጠቢያ የታይ እንቅስቃሴ
If you see shiny spots or “transfer layers” on the pad (grayish patches), it may be pad material stuck to rotor – a sign of uneven pressure or a glazed pad. Oil or grease on the pad surface (from a leaking caliper or wheel bearing) severely cuts braking performance and requires immediate repair.
Inspeksie Frekwensie
- Izikhathi ezijwayelekile:
Aim to inspect your brake pads at least every tire rotation (every 6,000–8,000 miles) or every oil change. A common recommendation is every 10,000–12,000 miles, or at least annually.
If u do a lot of city driving, towing, or hilly/mountain driving, check the brakes more often. Heavy or frequent braking accelerates wear.
Even between scheduled checks, stay alert for the warning signs above (noises, vibration, warning lights). Any unusual brake behavior warrants an immediate inspection. Remember, “better safe than sorry” – inspecting pads is quick and inexpensive compared to fixing rotors or accidents.
