Before you begin
The steps in this guide are used to replace the brake rotors on all Focus models in the 2005-2007 generation, except for the ST model, which has slightly different brakes. Caution should be exercised when working with brake and suspension components, and proper safety goggles should be worn at all times. Whenever working on your car's brakes and suspension, work on one side at a time. Keep the other side completely assembled so that you can reference it at any time. This guide includes steps to replace the brake pads, in addition to the rotors. It is strongly suggested that brake rotors are not replaced by themselves. Never drive a car if the brakes on one side only are changed, because the car will "pull" to one side.
