if your rotors r worn you see little groves on them that go all the way around these grove tend to have a rust color
damaged/ worn brake 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.
Pads are worn down Rotors are rusty and scoured Dirt and grit have been trapped between pads and rotors
depends on the condition od the pads. If worn or have groves etc from the rotors then replace.
No, you cannot flip rotors to extend their lifespan. Rotors are designed to wear down evenly on both sides, so flipping them would not be effective in prolonging their lifespan. It is recommended to replace rotors when they are worn out.
Could be the pads are worn down replace your rotors and pads could also be runout on the rotors
When they are warped or worn beyond legal limits.
Most probably due to worn rotors/pads.
If the rotors are worn too thin, they could snap apart while braking, leaving you with no braking power at all.
Your car probably has abnormally worn in tires, caused by misalignment. Worn rotors can cause this as well.
Brakes fading is usually a sign of overheating or worn pads. The brake pads need to make good contact with the rotors to have stopping ability. Check the pads for wear, and the rotors for bluing or grooves worn in them.
They can be a bit worn, but not much. Look at a new one or ask at parts store, thickness, then measure yours.
