No they do not! For example Front Rotors; if one rotor surface when turned on a lathe will exceed limits of safety (i.e. cutting away more metal from the rotor than is safe as regulated By D.O.T. (Department of Transportation ) then you need to replace the rotor. If the other turns out to only need a small amount of surface removed to make it usable then that can be done. Same thing applies to the rear disc brake rotors. Of course if both rotors are beyond safe resurfacing, then both should be replaced. HOWEVER it is possible that having calipers of a different thickness may cause them to perform differently causing a potential safety issue due to the fact that they will not have the same heat dissipation characteristics. I have not experienced this myself but this does seem to be the basis behind the recommendation of replacing them in pairs. IF I were to worry about then, I would probably only be concerned on wheels involved in steering.
What else can I help you with?
Do you have to change the rotors and pads at the same time if you have an AWD?
The brake rotors only need to be changed if they are worn beyond allowable specifications and should be changed in pairs. They do not need to be changed with the pads unless they are damaged as above or warped.
Do you have to purchase brake rotors in pairs?
Yes you do
Do brake rotors come in pairs?
You can purchase one or more.
Do brake rotors need to be replaced in pairs?
No just the bad one.
What if we changed the front brake pad rotors and sensor but only changed the back brake pad and not the rotors and sensor why would the light indicatir stay on the back rotors did not need changing?
Possible that the rear sensors are broken.
You changed your rear breaks and rotors and it now sqeaks and smokes?
It could be that the brake pads are dragging on the rotors.
Do brake rotors always come in pairs or can you get just one?
You can buy just one.
Is it necessary to change brake pads when changing rotors?
When rotors need to be changed usually the pads have worn down. It is always a good idea to change pads when changing rotors.
Why does a 2007 Dodge Grand Caravan needs brake pads and rotors changed at 16000 already?
Aggressive driving.
Why does your silverado smell like its burning after the rotors and pads were changed?
mine did the same thing and would not stop until i changed the brake lines also, then it stoped.
Changed front disk pads and rotors one brake seems to hang up intermittantly?
You need to bleed the system.
When i Changed rotors 2 years ago and the steering wheel shakes when the brake is applied?
i think your rotars need to be cut
