That depends. In general, brake rotors should be re-surfaced when you replace the pads. As brakes wear down, the surface of the rotor will become worn as well, and will not be even. Re-surfacing restores the rotor surface to a smooth, flat, uniform finish - which is a nice match for the new, flat brake pads. However, re-surfacing removes metal (it essentially removes all of the high spots until the whole surface is even with the lowest spot previously found). This will result in the brake rotor being thinner than when the car was new. All brake rotors have a specification for minimum thickness. If resurfacing the rotor causes it to be less than this minimum specification then it cannot be used on the car (at least by a reputable shop). So, if re-surfacing results in the rotors being too thin, they need to be replaced. In order to save the cost of re-surfacing first, a good mechanic should be able to tell you before s/he re-surfaces the rotor if it will pass the thickness specification after the re-surfacing. If not, then it will need to be replaced. Most rotors today can be resurfaced at least a couple of times before getting too thin. The exact specfication for your rotor will depend on the year and exact model of the car. Of course, you can always opt for neither. If you leave the rotor alone the brakes will be somewhat grabby, and will not be quite as effective since the braking surface is not optimal, but it's always an option.
no but it is recomended.
depends on the condition od the pads. If worn or have groves etc from the rotors then replace.
I recently got a quote for my 2003 Kia Optima brake pads & rotors to be replaced in the rear and it came to $183 before taxes. This price is to replace both pads and rotors completely. Usually rotors don't cost much to be turned.
Replace the pads, and the rotors. You need to change the brake pads and the rotors.
If the rotors are in good condition, not warped, not scratched, then you can replace the pads without turning the rotors. Inspect the rotors carefully.
1500 or 2500???
It will cost approximately $60, per wheel, to replace your brake pads and rotors. Mechanic shops that specialize in brake replacement are usually the cheapest. The automobile dealership is usually the most.
You do not need a scan tool to replace any brake pads. The wear is obvious.

how much to get brake pads and rotors replaced on a holden vt commodore
On my 2007 Sonata I had to replace the brake pads and rotors at 57000 miles.
The most common cause of this problem is warped brake rotors. Get it replaced soon. Whenever you replace rotors, you should replace the pads. The old pads will have conformed to the shape of the rotors, so braking efficiency and life will be down if you use them with the new rotors.
