So basically whenever Im riding my bike there's a huge resistance due to the brakes always touching the tires even though I don't even press on my brakes.
There should be a little screw on the side of one or both brake arms. What that screw does is to increase or decrease the return spring tension. Generally turning the screw clockwise will cause that brake arm to move away from the rim. Fiddle with them and see if you can get the spring tension balanced on both arms.
