I've looked everywhere for answers to these questions. I've just changed my brake pads but am unsure how brake rotors are supposed to look or feel. What does turning them do? If a rotor isn't perfectly smooth, what effect does it have on your brakes? Thanks.How do you know when a brake rotor is bad? How do you know when they need to be turned?
get rid of that Toyota van already, Ray!!! do you see many of these on the road? there's a reason why not......How do you know when a brake rotor is bad? How do you know when they need to be turned?
Rotors over time wear thinner in thickness..... for each make/model there is a minimum thickness of the rotor before it is deemed unusable or unsafe..
if the rotor isn;t perfectly smooth it will wear the brake pads abnormally or faster sicne it has to grind itself down to fit the grooves of the rotorHow do you know when a brake rotor is bad? How do you know when they need to be turned?
If the rotor needs turned you will feel a vibration while braking.
They are usually stamped with the minimum thickness that they should be turned to near the wheel stud area.
I personally never turn them, and just buy new ones because the new rotors usually cost only a few more dollars than the cost to turn the old ones.How do you know when a brake rotor is bad? How do you know when they need to be turned?
the rotors should be turned everytime the brakes are replaced so the pads break in evenly and you get full pad upon brakeing, the symptions of a bad or warped rotor is a pulsating feeling in the brake pedal when applying the brakes.How do you know when a brake rotor is bad?

Typically a bad rotor will either be warped (high bumps in random places) or wavy (high and low spots radiating out from the center). You can use a straight edge to see how straight the rotor is in various areas to get an idea if its ok or not. But honestly with the low price of imported rotors at most parts stores, virtually no one turns rotors anymore. My friend who runs his own shop sold off his rotor resurfacer several years ago, you can't charge customers 15 bucks a rotor to turn them when new ones are 25, so you don't waste your time you just sell them the new rotor and make your money marking those up and installing them.How do you know when a brake rotor is bad?

If your steering wheel shakes when you apply the brakes you should have them turned. If you noticed that the rotors looked as if they had grooves worn around them, you should have them turned. If you had hot spots or discoloration, it wouldn't hurt to have them turned. If you've had them turned more than once or twice and a lot of material was removed then you should consider having them replaced. The guy turning them should be able to put a set of mics on them and tell you if they are getting too thin to turn again.How do you know when a brake rotor is bad?

i own a shop and you can look at them and see if the have grooves cut in them or odd markings on them that shouldn't be there,they should look smooth,you can also tell this by if they wobble when you put your foot on the brake pedal also,if you feel it go up and down a lot this means their warped,most of the time you can just remove the wheel and rotate the rotor a little and see if it wobbles or has deep grooves in it,if you see any of this you either need to get these turned or get new ones for it,good luck with it,i hope this helps.How do you know when a brake rotor is bad?

a brake rotor has a musurement on each car,most of the time marked on the inside of the rotor.if you put pads on its a good idea to have thrm turned.reason is there can be high and low spots on the surface and this can cause the brakes to shakeor make the car jerk when applied.most rotors get damaged by the driving habits of the driver,if you drive fast and hit your brakes to make a quik stop,that causes the rotors to get the high spots in them.also riding the brake will cause this.if you drive regular and not alot of stopping involved,you wont have to cut the rotors too much.just enought to get the layer off the surface of the rotor from build up.How do you know when a brake rotor is bad?

a good brake shop will take a micrometer that measures thickness and measure each rotor,then compare results to the measurements that is stamped on each rotor/hub if within limits they usually turn them and that provides a smooth surface for the brake pads -----with a un-even surface or a ridged surfaced that will cause the pads to be ridged or not wear evenlyHow do you know when a brake rotor is bad?

the rotors make a squeeking noise and when you stop you kind of have a buzzing sound and it will harm your brakes life and its better that you change them as soon as possibly because the brake life will go out and it will get ruinedHow do you know when a brake rotor is bad?

Your rotors can be spot checked with this trick. If you can not write a smooth line across the surface of the rotor with a regular ball-point pen; it needs to be turned if it has enough thickness to be machined. What I mean is to try to write your signature in several places on the %26quot;cleaned%26quot; rotor, without any blank spots or skipping, if you can; the rotors are smooth enough for good pad contact.
This only works on solid faced rotors; this is Yahoo Answers after all.How do you know when a brake rotor is bad? How do you know when they need to be turned?
the rotors should be turned every time you replace the brake pads. they should be as smooth as a babys butt on the surface that they touch the brake pads. rotors can only be turned down to a safe minimum thickness which is measured in hundredths of an inch. take them to your local parts store to have them measured and possibly turned. if you dont have them turned, the uneven ness (sp) and grooves take away from the total surface area that your brake pads touch them and your brakes will overheat. the excessive friction on the smaller surface area creates intense heat. the pads and the rotors should mate up together nice and smooth. if you dont turn them and the heat builds up the rotors will warp, or become out of round laterally causing a pulsating feeling in the brake pedal.How do you know when a brake rotor is bad?

when your rotors are bad,you will get a pulsation in your brakes,and when you get the rotors turned,you should get even braking action,without pulsations.
