Brakes are still squeaking
ok after I received the new pads and mounted them to my rotors and took it out for it's breakin, the car is still squealing like h#ll .. it's only from the pass. side too.
the new pads did there squeal, but are good now.
and it's not just when stopping, it's a constant so something is out of place.
the only thing that i could think of is maybe the brake pad retainers might have been damaged .. but I looked at them .. and they seem fine.
any thoughts?
not that it matters but,
Napa Rotors: $25 special
PFC Carbon-Metallic Pads
...thanks.

Le me get this right?
You're getting squeal even when your not using the brakes?
It's only on the right side (passenger)?
Can you tell if it's the front or rear?
For this to happen and it be caused by the brakes, it's a mechanical issue.
Either the rotor run-out is off causing the rotor to make contact with the pads at certain points. This doesn't mean the rotor is bad, run-out issues can be caused by the hub, wheels or even wheel bearing.

or
The Caliper is not mounted square on the carrier or it's binding on the guide pins. Make sure the guide pins are greased with caliper grease.
Can try remounting the caliper and check the pins. Look for any obvious gauges or scratches. While you at it push the piston back agian.
or
The caliper piston(s) are not achieving enough roll-back, usually because they're seizing in the bore from corrosion, bad seals or they're askew in the bore.
Normally these problems would be accompanied by poor pedal feel, pedal vibration of judder. But, not always. Some systems have "lower sensitivity" than others.
There is also the possibility that it's the wheel bearings and it's just coincidental that you did the brakes at the same time.

Carefully look at the hardware kit on the caliper bracket, alot of times the inside edge of the thin metal guide will bend outward just enough to scrape the rotor. You might have to take the caliper back off to see it.
