A worn or warped rotor can show up as pedal pulsation, shaking under braking or grooves on the face. Calipers, pads and other brake parts can produce similar symptoms, so find the cause before you replace the rotor. During a brake service with the wheel off, look over the rotor faces and measure the thickness against its discard thickness. This listing is one rotor; the front axle uses a pair, and both sides are normally replaced together.
