This is a front-axle disc brake rotor. Signs a rotor may need replacing include pulsation through the brake pedal or steering wheel, grooving or scoring on the braking surface, and vibration under braking. For even, balanced braking, it's best practice to replace the front rotors as a matched pair; this listing is for one rotor.
Is this a front or rear brake rotor?
It is a front-axle brake rotor. For balanced braking, replacing both front rotors together as a matched pair is recommended.
Will this rotor fit my vehicle?

No. It arrives new in the box, ready to install, and is designed to meet the same form, fit, and function as the OEM rotor with no modifications required.
How many rotors come in this listing?
