Brake job, now a noise.

[84LX89GT]

The way to brake up the record finish is to take 130 grit sand paper (says so in ford manual) and while it's on the lathe, with a sanding block, make a uniform finish accross the rotor either by creating a crosshatch pattern to bed the pads or just holding and breaking up the record finish. Alot of good rotors come with a crosshatch pattern, so you don't have to refinish them. All rotors need to be cleaned before installation because metal/abrasive particles can become lodged in the pad and make noise and reduce it's stopping power. You also have to make sure not to get grease on the rotor because that will contaminate the pads and create a pulsation/noise when braking from them grabbing and releasing.
another thing that causes pad vibration (squeel) is by forgetting to lubricate the caliper glides (where the caliper pins go through). If a glide hangs up it will cause irregular pad wear and also the pad may not fully press against the rotor and will vibrate and create a noise.
Sometimes a noise will go away after you put some miles on them, but you may not be so lucky.
Good luck,
