Three online references for installing new brake rotors are AutoAnything, TopBrakes, and 2Carpros. All three of these guides feature step by step installation guides and graphics or video to assist with the task.
Installing brake rotors is considered to be a task of average difficulty. The guide at 2Carpros.com features a list of all of the necessary tools, which are all common with the exception of a large "C" clamp or caliper spreader. The AutoAnything guide contains a video, while the TopBrakes and 2Carpros guides contain still images which may be more useful if the installer intends to print a copy of the guide for reference during the installation.
It is recommended to install new brake pads at the same time as brake rotors since the task involves removal and replacement of the same components, and since worn brake pads might damage the new brake rotors.
