Noise following front brake job

[dlbaugh]

2002 Astro AWD

About two weeks ago I replaced my front pads and had the rotors turned. And about one week ago I started hearing a noise from them when braking with light to moderated pedal pressure. Sometimes the sound is very regular as if related to the rotating hub/rotor. And sometimes it appears more random or eratic.

If this sounds familar to anyone can you clue me in to the problem and/or solution you encountered?

I have removed the wheels and examined brakes, only to find the caliper pins are tight. The pad clips are very snug and holding them in place. I can grab the caliper with my hands and slide it a little. This brake job was the first time I have used that quieting goop that you spread on the back of the pad that goes against the piston.

All input is greatly appreciated.

Thank you,
Donny Baugh

see if its a problem after the brakes get warmed up.it maybe a bad rotor or machined improperly.
