Brake Disc Caliper problems of the 2010 Subaru Impreza

Car was purchased from a dealer who purchased the car from new york auction. After purchasing and replacing common things you would after buying a used car, we recently replaced the front brake pads, and after installing the pads, and driving the car around, and breaking soft and hard the car was vibrating violently from a stop from 60 mph, after pulling over I notice smoke and burning smell coming from the front driver side tire. After getting the car home and pulling the driver side apart, I noticed the brake caliper's main pistons froze up and wasn't working properaly , due to so much corossion and rust from the car, coming from new york. , the passenger side was barely making contact with the rotors, causing the driver side brakes to stop the car, which is causing severe vibrations and longer time and distance to stop the car. The car was thoroughly washed and cleaned of all salt residue and rust. Replacing both front calipers, pads, and scheduled a service appointment with my Subaru dealer to address a recall that's still not completed on the car.
