I have a 1994 Nissan Altima GXE. I had some brake work and front wheel work done around Christmas time. The control leg, an axle, and some other small things were replaces, along with the entire brake system. However, when I turn left or go in reverse, I hear this shrill, metal on metal sound that continues until I slam on the brakes or turn right. It even happens when I gently press on the brakes. I really think it is my brake pads (they are worn and I got them way before my brake job). I just want to the sound to stop, and I was hoping that someone could help me out or give me an idea of what it could be.

You are likely hearing noise from the brake pad wear sensors, telling you it's time to replace them. If you let it go much longer, the discs will get damaged. Here's how to do the job yourself:
