When I change my brake pads how imortant is it to do the rotors?

I'm about to get my brake pads done because they are screeching like crazy when I stop. The mechanic said I should get my rotors done too. He hasn't actually looked at the cat yet. How impotrant is this, and do I have to do this at the same time? Also, how do I know if those need to be done too?

Thnaks, usually my friend helps me with my car but I have to go to the shop this time, so I'm confused.



p.s. I drive a v6 mustang, if that helps.When I change my brake pads how imortant is it to do the rotors?
if the rotors arent warped or gouged from previous brake pads i wouldnt worry about it. easy way to tell if rotors are warped is at medium speeds and highway speeds, your steering wheel will vibrate back/forth either violently or steadily...you know the annoying steering wobble...thats warped rotors 97% of the time.



its common practice to have rotors turned too if they are only slightly gouged or warped.



the rattling is most probably the dust shield on that wheel. its probably cracked and just flapping in the wind against the suspension and the wheel. it just prevents dust from the brake pads from going everywhere. I've had several cars I just ripped them the rest of the way off and left it.



if the car is running fine and not throwing codes, then the cat is ok. if the cat clogged up, you either would have a really crappy running car or it wouldnt crank at all. he cant physically check the cats other than looking at the external cases. too many bends in the exhaust system to even see the honeycomb.When I change my brake pads how imortant is it to do the rotors?
when the pads are changed, the rotors are turned at the same time. this makes them smooth and straight. if the rotors don't meet a certain thickness, then you replace them with new ones. before the rotors are turned, the mechanic will measure them and tell you if you need new ones.When I change my brake pads how imortant is it to do the rotors?
the only way to know for sure if the rotors need changed or %26quot;turned%26quot; is to physically touch the rotors and see if they have deep scratches or grooves in them. ususally (not always) u will have to replace them about every two sets of pads. %26quot;Turning%26quot; means to grind them down so they are smooth again. Sometimes its as cheap to buy new ones as it is to have the old ones ground.When I change my brake pads how imortant is it to do the rotors?
Rotors should be machined at same time.When I change my brake pads how imortant is it to do the rotors?
It is good to change the rotors as well. But you dont have too. You should soon. But if you dont have the funds dont stress it. The most important thing is to stop the screetch.



I changed my front and rear pads but not the rotors. I plan on changing them soon but it hasnt caused me anything. My pads are still screetching in the front because I got some cheap and too hard pads. Im going to take them out since the shop didnt do it and put some antisqueal and see if that works. If not Im returning those brakes and getting my money back for better ones.



Its just easier to change the rotors while changing the pads but some people dont have all that money to do so. Once they take off your caliper it would be a simple swap to just put the new rotor on. Its a way they make some easy money as well. But it wont kill you. Just get them changed too or see if they can be resurfaced if they arent bad. Go somewhere and get a free brake check. In fact get second opinions as well. Nothing wrong with that.When I change my brake pads how imortant is it to do the rotors?
If the rotors are scratched or have rough surface or groves in the surface then any new pads you put on will be worn very fast.It is important to have them turned or replaced if needed but if the mechanic didnt even look at them...you could see yourself without taking the tire off if you can look through the wheel spokes or even feel the rotors.When I change my brake pads how imortant is it to do the rotors?
Screeching noise is very normal , since there is a sensor attached to the pads to alert you when it's time to get new pads , but keeping on driving your car with this noise for a long time , will damage the rotors , then you'll need to get new ones ( they run about $25 each), you should have the rotors TURNED when you replace the pads , %26amp; if they worn out then you better get new ones . Good Luck
