So about 3 months ago I changed my break pads out. Everything was perfect up until about 2 weeks ago when I noticed a terrible squealing when slowing down. I figured it was probably from the dirt and pollen because that was the issue in the past. Anyway, today I was pressure washing my truck, and when I hit the wheel, the fuggin' wheel well fills up with smoke (a light grayish color). I got closer and hit it with water again, and sure enough smoke was coming from the rotor. Really don't know what the hell it was. Any help is much appreciated.
