Brake Pads are not that hard to change, but instead of a website, you should go to an auto supply store and get the workshop manual for your car model/year range. Before you buy it, look through the section on changing brake pads, and see if it is something you are willing to do. Just remember, you life and the life of your passengers may depend on your brakes functioning correctly. Also, if you have it professionaly done by an honest shop, they will tell you if you really need to replace any other brake parts, like the rotors.

Anyone knows a website I can get step by step instructions on how to change brake pads?
