If you are buying a used car in addition to doing the other fluids that we have suggested that you check, you also need to check the vehicles brakes. Brakes on a vehicle are one thing that are designed to wear out. It is the friction between the rotor and the pads that stop the vehicle when you apply the brakes. If both the pads and the discs were made out of hardened steel you wouldn’t get any stopping power. In this article we will cover checking the front brakes on cars and trucks. On newer cars with open rims it can be fairly easy to get a quick glance at the condition of the brakes. The front brakes are anywhere between 60 and 70 percent of your stopping power. When you first walk up to the vehicle you can look at the front brake rotors by looking through the rim and checking the condition of the rotors. Make sure that the vehicle hasn’t been driven, otherwise they will be to hot to touch. Hopefully the rims are open enough so that you can get a good glance at them. Try and see if you notice any ridges across the rotor. If you can stick your finger through the rim you can also feel the rotor to detect if there are ridges across the rotor. If there are, there is a good chance that the vehicle will need a brake job soon. If the rotor is nice and smooth then that is a good indication that the brakes are in good shape. You will also want to open the hood and check the brake fluid. There is either a level indicator on the outside of the brake fluid canister, or there is a dip stick on the filler cap. Make sure that the fluid is within the specified limits. If it is low it could be another indicator that the vehicle is in need of a brake job. As the pads wear, the pistons in the calipers extend farther requiring the use of more fluid. Now go ahead and get in the vehicle and turn the ignition on, but do not start the car. Take notice of all of the indicator lights on the dash. Does the vehicle have an ABS light or brake light? ABS light is Anti-lock Brake System and under extreme braking conditions diverts braking power to other wheels to keep the vehicle from going into a skid. This light is usually yellow on the dash and a “Brake” light is usually red. Now start the car and be sure that these lights go out. If they turn off, then everything in the brake system should be in working order. If an ABS light or Brake light remains on, then the brake system is in need of servicing. Next, you want to go ahead and drive the vehicle. While you are driving apply the brakes and take notice as to what the steering wheel does. Does the vehicle continue to go in a straight line, or does it pull to one side or another. The vehicle should continue to go in a straight line, if it pulls to one side or the other then one side of the brakes is working harder than the other and indicates that a brake service is needed. You also want to listen while applying the brakes. Do they make a squealing noise or grinding noise? If they squeal it is an indicator that a brake job is due. Many cars are now equipped with what are called “squealers” on the brake pads. It is designed so that when the pads wear down to a certain point the “squealer” touches the rotor letting you know the vehicle needs pads and helps protect the rotors. If you hear grinding – well it definitely needs to go to the repair shop to have the brakes looked at. On newer vehicles that you are considering purchasing, you can also order a vehicle history report to see if the vehicle has been maintained by the dealer and if it shows time for servicing. However, the vehicle may not have been maintained by the dealer so these records may not be available. In any case, before you buy, you to ask if you can take the vehicle to your local mechanic to have it checked out to give you a little more piece of mind.

Ako kupujete polovnih automobila pored obavljanja druge tečnosti koje smo predložili da provjeriti, također trebate provjeriti vozila kočnice. Kočnice na vozilu su jedna stvar koje su dizajnirane da istrošiti. To je trenje između rotora i jastučići da zaustavi vozilo kad zakočiti. Ako su napravljene kako jastučići i diskove od kaljenog čelika ne bi odgovore na sva moć zaustavljanja. U ovom članku ćemo pokriti provjeru prednje kočnice na automobile i kamione. Na novije automobile s otvorenim felge to može biti prilično lako dobiti brz pogled na stanje kočnice. Prednje kočnice su negdje između 60 i 70 posto vaše zaustavnu moć. Kada ste prvi put hodati do vozila možete pogledati na prednje kočnice rotora gledajući kroz RIM i provjeru stanja rotora. Pobrinite se da vozilo nije prešao, inače će biti vruće na dodir. Nadam se da su felge su dovoljno otvoreni, tako da možete dobiti dobar pogled na njih. Probajte i vidjeti ako primijetite bilo grebena preko rotora. Ako možete držati prst preko ruba također možete osjetiti rotora otkriti ako postoje grebena preko rotora. Ako postoje, postoji dobra šansa da će vozilo ubrzo treba posao kočnica. Ako je rotor je lijepo i glatko onda to je dobar pokazatelj da su kočnice u dobrom stanju. Također ćete želite otvoriti haubu i provjerite ulje za kočnice. Tu je bilo indikator na izvan kočnice tečnosti kanister nivo, ili postoji dip štap na lijevku. Pobrinite se da je fluid je unutar navedenih granica. Ako je nizak to bi mogao biti još jedan pokazatelj da je vozilo u potrebu za posao kočnice. Kako se pločice istroše, klipove u čeljusti mjeri dalje zahtijeva korištenje više tekućine. Sada idi i dobiti u vozilu i uključite paljenje na, ali ne upali auto. Primjećivati svih lampice na instrument. Does the vehicle have an ABS light or brake light? ABS svjetlo je protiv blokiranja kočnica sustava i pod ekstremnim uvjetima kočenja preusmjerava snage kočenja na druge točkove da zadrži vozilo ide u mini. Ovo svjetlo je obično žuta na crtica i “Kočnica” svjetlost je obično crvena. Sada pokrenuti automobil i biti siguran da ti svjetla izlaze. Ako su isključite, onda je sve u kočionom sistemu mora biti u ispravnom stanju. Ako ABS svjetlo ili kočnice svjetlo ostaje na, onda je kočioni sistem je potrebna servisiranja. Sljedeća, želite ići naprijed i vožnju. Dok vozite koči i uzeti obavijest o tome šta volan radi. Da li je vozilo i dalje ići u ravnoj liniji, ili se to povući na jednu ili drugu stranu. Vozilo treba da nastavi ići u ravnoj liniji, ako vuče na jednu ili drugu stranu onda je jedan strani kočnice radi teže nego drugi i ukazuje na to da je potrebna radna kočnica. Također želite slušati dok primjenom kočnice. Da li oni napraviti cijukanje ili šum? Ako oni cvili to je pokazatelj da je posao kočnica je zbog. Mnogi automobili su sada opremljeni ono što se zove “Squealers” na kočione pločice. To je dizajniran tako da kada se pločice istroše do jednom trenutku “dostavljač” dodiruje rotor puštajući znate vozilo treba jastučići i pomaže u zaštiti rotora. Ako ste čuli za brušenje – i to definitivno treba ići na servis da se kočnice pogledao. Na novija vozila koji razmišljate kupnje, također možete naručiti vozilo izvještaj povijest da vidim da li je vozilo vodi trgovac i ako pokazuje vrijeme za servisiranje. Međutim, vozilo možda nije održava dilera tako da ovi podaci možda neće biti dostupni. U svakom slučaju, prije nego što kupiti, da se pitam da li mogu uzeti vozilo sa svojim lokalnim mehaničar da ga odjavljena da vam dati malo više komad uma.
