You can only have them turned a few times until they are too thin to be considered safe. Usually this thickness is stamped on the rotor.
Front or rear? discs or drum? rotors or drums turned(resurfaced)or not? Many times when you just replace pads without resurfacing rotors will tend to be noisy and sometimes overheat causing warpage,pedal will pulsate upon application.Good luck
( 2 rotors on the front ) one for each DISC brake
As long as your rotors are not warped, or you have not let the brake pads wear to the point they defaced the rotors, there is no need to change them. Just install new brake pads. Rotors can last the life of the car.
Disk brake pads are usually somewhere between $15 and $30, depending on the vehicle. If you can do it yourself and you don't need calipers or rotors it shouldn't be too expensive. Most vehicles require new rotors when you replace the brakes, in fact, many mechanics won't even replace brakes without replacing the rotors. In years past you could resurface the rotors but that is less common now. Unfortunately, many shops were resurfacing rotors that were already too thin, and many vehicle manufacturers are now using rotors that cannot be resurfaced. Rotors typically cost between $30 and $60, and can go much higher for European vehicles and trucks or SUV's.
That all depends on how the vehicle is driven, the quality of brakes used, and how soon you replaced the brakes when required. Some people don't have a clue a to the "squeeling" sound they hear from the front brakes and what it means! If you continue to use the brakes after hearing that noise, it won't be long before you're grinding away at the rotors! Overall, the rotors last a long time and can be resurfaced several times. One word of advice: Use a mechanic you know! The large "brake centers" will for certain tell you NEW ROTORS are definitely needed. That's how they make their millions! Only at those "shops" will it cost you $800.00 for a brake job! Stay away from those people and find yourself a good highly recommended mechanic!
If they are warped, they need to be turned, if they are groved, they need to be turned. If they are glazed, they need to be turned. In general, if you are working on the brakes, they need to be turned.If they are too thin (not wide enough across) to be turned, they need to be replaced. Many newer rotors are not thick enough to be turned, so you just replace them every time you replace the brakes. Most auto parts retailers will measure the thickness of the rotors for you and tell you if they can be turned.
There is no difference between brakes and rotors because the rotor is just one of the many parts that make up a brake. The function of a brake rotor is to stop the wheels from spinning. The rotor is what the brake clamps hold on to stop the car.
Your front brake rotors are warped. They need to be removed and turned true on a lathe. Many auto parts stores offer this service.

It's pretty straightforward. You will need to change the spindles, brake lines, brake hoses and master cylinder. You will also need to install a proportioning valve from a disc brake car, preferably another Chevelle. Stick with stock calipers and rotors if you intend on using stock wheels because many of the aftermarket disc brake setups have larger rotors and calipers that will NOT work with stock wheels.
