i dont realy think you should be changeing your brakes if you do not no what you are doing, i work in a garage and have seen so many f**k ups by incompetent DIY ers , so my advise , if you dont no then dont do it and get some to who does no.

Suggest you buy a Haynes manual for your car. It will step you through the procedure with pictures. This should also help you decide whether you are competent to be dealing with something as potentially dangerous as your brakes.
