Have you checked the brake fluid? You might have to change master cylinder or you might check to make sure there is not a vacume leak.
There is no need to spend the money if it doesn't need done. Typically your rotors last longer than your brakes do anyway, so you should be fine for a while.
A common reason is that the front rotors have warped. Go check out WikiAnswers on the topic of "warped brake rotors". Rotors should wear out smoothly in normal driving. Use of the brakes that generate lots of heat (hard braking, riding the brakes) will result in warped rotors.
you might have to bring it to a brake lave to size up the rotors and brake drums.
Your rotors had the grooves before, from the old pads. You should have had them turned. Next time check rotors at time of fitting new pads. If you can see or feel grooves then they should be repaired.
take brakes off and calipers off, next rotors should come off easily.
All brakes turn kinetic energy into heat, but you should not touch disk brakes because the oil in your hands will degrade their performance
your brake rotors are warped. You should repalce you brake pads and have the rotors resurfaced if possible, or replaced.

everytime you change brakes you should have rotors turned by an automotive shop or store. They will tell you if they can be turned anymore and if not you will have to buy new ones.
yeah it will have scratches on them you are using your brakes my friends its not like your brakes are made of cloth or sponge ofcource its normal for rotors to have scratches on there but makes sure they are spread evenly on there that they were installed correctly
If your brakes work going backwards better than forwards, you should replace your front brakes. You can get your rotors turned to save time, as well.
