Obviously you took the drums from the wheels. Did they come off easily? If they fell off easily the brakes aren't adjusted properly. I would go ahead and take the springs and shoes off and clean everything then grease the flat spots on the backing plates where the shoes ride. Almost all of your pedal feel is the rear brakes. You should be able to have a helper gently work the pedal and see movement with the assembly. If everything checks out, you need to adjust the brakes. After assembly, turn the wheel and tire by hand and adjust the brakes until you feel resistance. It's ok if the wheel is slightly hard to turn when you have it right, the brakes will wear in. Take it to Midas or a similar shop and have them pressure bleed the system with new fluid.
