Here is a way to check it, but you need to be careful. With the vehicle moving, hold the parking brake release and press on the parking brake to see if you get the same response. Make sure not to jam the brakes because if the rear brakes lock, it will cause it to fish tail. Also, make sure to hold the release so you can actually use the parking brake like you would the regular. THey won't stop you very fast, but only the rear brakes will be working. If the problem is in the back, you should feel it and then confirm that the problem is in the rear.
Make sure to do this where there is no traffic or people.
Let me know what you find.
