You need a copy of the manufacturer's service manual. That will have pages of instructions with line drawings.

You can also find an online service manual for your vehicle by going to the top of this page, pointing to "Repair and Service", then click on "Manuals". That will take you to a site where you can buy a subscription for your specific vehicle. It includes all the stuff from the manufacturer's service manual, plus recall notices, service bulletins, and other information.

Be aware there's WAY more to a professional brake job than simply hanging new pads on the car. The rotors need to be measured to see if they're still thicker than the published legal limit. If they are, they need to be machined so both sides are perfectly parallel, and so the pads make full contact, otherwise there are going to be grooves that prevent that. Most auto parts stores can machine rotors for you, but considering the low cost of new ones, you're better off that way.

There are places to lubricate with special high-temperature brake grease. You must not get any grease or contaminants on the rotor or pad friction surfaces. When the calipers are removed, don't allow them to hang by the rubber hoses.

Most importantly, use a click-type torque wrench to properly tighten the wheel lug nuts when you're done. Anyone at an auto parts store or repair shop can tell you the proper setting. 90 foot pounds is typical for steel wheels, and 80 foot pounds is common for cast wheels, but those numbers are just a guess.
