Is it true that when you change your brake-pads you have to?

something to your disc-brake.



See about 6 months ago I got my brake-pads changed and put new ones in by a friend who is a mechanic at a dealership.



When i take my car to firestone today to do an oil-change, the mechanic tells me the guy who did my brake pads is an idiot. And that you're supposed to %26quot;cut%26quot; the disc-brakes everytime you change the pads, that anyone can simply change the pad by reading the manual.



Is this true, or does he want me to pay him for something that is unecessary, I did notice the front-right disc was scratched, while the other ones looked neat.Is it true that when you change your brake-pads you have to?I think it's great that the guy at the oil change place looked your car over for other possible problems. That is one of the reasons to get your car service regularly. But he needs to keep his opinions to himself as far as who did it before and how they did it.



The guy at firestone has just had it drilled into his head that it is true. I have changed brake pads for the last 35+ years and I may have had the rotors turned only 2 or 3 times. Once in a while, if the rotors are glazed real bad, you can just take some sand paper and ruff them up. Other than that, you only need to %26quot;cut%26quot; or turn the rotors if the brake pad wore down to metal and cut into the rotor. It is NOT necessary every time you change the pads.



Hope this helps and good luckIs it true that when you change your brake-pads you have to?Hi, You say you get an oil change and they look at your brake pads. Was this with your approval? Anyway usually when you do disc brakes you take a cut off the rotors to make sure every thing is true, as rotor to pads.Ask the person who did the brake job if he turned the rotors. God LuckIs it true that when you change your brake-pads you have to?I think he meant you should turn the rotors, that is, machine them back to a smooth surface using a lathe. This is a good idea, but definitely not necessary. If your rotors are not gouged, and there is no run out (wobble) then the new pads will quickly wear to fit the contour of the rotor surface. No resurfacing is necessary.Is it true that when you change your brake-pads you have to?You dont have to ever, but if the rotors are realy eaten up you should have them turned if your friend is a mechanic he would have told you that they need turning dont pay some crook 150.00 to turn them have your friend to take them off take to autozone they will turn them for you.Is it true that when you change your brake-pads you have to?You have slider pins that need to be regressed, or your pads will wear unevenly. The calipers can be compressed back in in order to place it back on the rotor. Not too hard of a job you can do yourself if you want to save money.Is it true that when you change your brake-pads you have to?well it depends on you. if you want to fix them the right way. he was just telling you. you are the owner of the car. you decide what and where to get them done. the only thing that is going to happen. is your pads are not going to last longer.Is it true that when you change your brake-pads you have to?1 if rotors are good they DON'T need turning

2 old days rotors were thick and easy to %26quot;turn%26quot; machine

3 todays rotors are thin.and when turned get thinner then warp,,,.and because 1/2 the cost is labor i just put nice new ones on when neededIs it true that when you change your brake-pads you have to?there just trying to get your moneyIs it true that when you change your brake-pads you have to?This is a tough question to answer. If when you apply the brakes, there is no vibration, then everything should be OK. If you just change the pads, and the rotors are scuffed up by the old pads, the new ones will take on the shape of the rotors deformities. It is normal to cut the rotors when you replace the pads, but many cars today are engineered so preThaiely that when it is time to change the pads, the rotors have automatically worn out with them. In other words, to save weight on the car, the rotors when new are very thin and are designed to be disposed of when the pads are replaced. Many Asian cars are like this. It also makes it easier, in a way, since the old rotor turning machine is no longer required to do a brake job. Most American car brakes will have rotors that last for 2 pad changes. It all depends upon the car, and it's engineering features. If the rotor is too thin, then the caliper pistons will extend too far and cause problems with leaking. Goodluck!!Is it true that when you change your brake-pads you have to?What he is referring to is lathing the brake disc (cutting the disc). After a disc has been on a vehicle for a long time the metal is worn away by the brake pads from braking. This creates a ridge of uneven wear on the outside and inside of the disc, and can cause improper braking performance if new pads are installed without the brake being lathed. The disc will be placed in a brake lathe and the uneven parts cut off to make the disc even again.



If your discs were very worn and uneven they should have been machined. Have the mechanic from the dealership show you what is wrong with the brake discs- you should be able to see the uneven surface of the disc if is it present.
