I recently changed my rear brake pads and everything went back on with no problem but when I went for a drive and brought it back home I could smell n feel the heat coming off the brake pads and rotor. When I went for the drive everything time I braked I could hear a squealing sound and rubbing coming from my rear brakes but the driver side is heating up way to much, more than the passenger side and I could feel the car be held back when I take my foot off the pedal to glide. If anybody has an idea of what it can be please feel free to let me know anything will help. I'm thinking I'm might have to get a new caliper

It leaks when I have the air conditioning on.
