Brake rotors are designed to slowly wear down, ensuring that your vehicle will stop and slow down safely. Often times rotors may warp, causing a vibration while coming to a stop, or may just wear down below their specifications, and need replaced. Restore the stopping power in your vehicle and pick up a new set of rotors to get back a great feel.
If it's time to replace your rotors, then you should also replace the brake pads to get maximum braking performance. With a new pad and rotor set on your vehicle, stopping will be completely restored. Enjoy the stopping you felt when you first obtained your vehicle.
With new pads and rotors, you need to make sure they are bedded and mated with each other. To be sure they are, follow the brake pad bedding procedure on ECS Tuning's site.
