I have a 2005 chevy silverado 2500hd. When I apply the brakes at a low speed a rough grinding noise comes from the front driver side tire. The harder I push the worse the sound becomes. I put on new brake pads a month ago and the rotors are in good condition. Even with the noise there are no other issues with the braking. I'm not sure why this started happening and cant find anything wrong. Any ideas would be very helpful. Thank you!
You don't mention having the rotors turned when you replaced the pads. Even if you can't see or feel them, there will be some groves in the rotor. This can conceivably cause the sound.
Assuming the rotors were not turned, you should re-do the brake job. Get the rotors turned AND use new brake pads.
Alternately, if you did not use the lubricate between the backs of the pads and the caliper, it can cause noise.
