Okay so I just got new pads and rotors all the way around and they work good, but when I turn to the left (only left ) I hear a squeak/ squeal noise I don't know what could be causing this I need HELP PLEASE

 

Sure the front rotors were installed right? Sounds like a wheel bearing problem to me.

 

Pull apart rear brakes and clean and grease the pins. Common overlook. I've found plenty f bodies with the pins seized in the abutment causing the caliper not to float with the axle and drag and eventually glaze. Clean up the rotors and pads before you put it back together if they are glazed.
