There is a possibility the your local Midas shop mis-diagnosed the caliper seize up. The calipers may have been good. They just need to be loosened to remove the pads by turning a screw with an allen wrench after removing a cover bolt on the caliper. It is not possible to remove the rear brake pads without first loosening the screw in each rear caliper. Forcing the pads loose by mechanical means will destroy the caliper.
