My car had replaced front brake pads in early 2012 from Big O Tires. Now I have been hearing a grinding, squeaking noise when pushing in on my brakes lightly or softly. When releasing on the brake, it seems like it sticks and the noise is just not pleasant to hear from the inside for my passengers (myself) nor anyone out near my car. I took back to the place where y brakes were fixed and they did not identify an issue; mainly because it's under warranty and they don't want to fix their own mistakes, -_- wish I knew about cars so I could fix it myself.
