Not that hard and if you get the brake pads from Auto Zone, they will have the step by step instructions for you to get the job done. If you need a loner tool, they have that too.
The rear brakes is straight forward. It's the identical method like the front, with the exception that it used the inside hub of the rotor as the drum for the parking brake. Take off the 2 caliper bolts and slide the caliper off the rotor. Grab the rotor and slide it off.
There is no bridge to remove. The caliper piston is reset by compressing it, like the fronts. If you are going to replace the pads, it would be a good idea to replace the park brake shoes and hold down hardware as well.
