Why would my brakes squeal after the pads were replaced?

We had our front brake pads replaced and now there's a squeal when you slow to a stop. Does anyone know what could be causing that?

Yeah, they did it wrong. Brought it back and they fixed it.

It could be cheap brake pads, the pads might need to be broken-in, or the tech could have forgot to add lube to the slides and now the brakes are not disengaging fully when you let go of the pedal, causing vibration.

It's only the last little bit of the stop that makes the noise. Rotors look good, so I assume I need to break them in or lube was forgotten. I'll try breaking them in today and see if that helps. thanks.

What was the result?

Either the screamers were installed wrong or you drive a dodge.

What a lot of people don’t know is the EPA is not allowing copper in brake pads anymore. Without the copper the brakes squeal a lot more often now. It’s fun trying to explain that to a customer at the dealership that just had brakes put on a month ago. They do have a copper paste that you can put on the outside of the brake pad. I have had luck with that.

Did you replace or resurface the rotors? If not that’s probably why.

Yes, they redid the rotors too.

Either they used cheap brake pads or they did a poor job of resurfacing the rotors. I would take it back, brand new brakes should not be making noise.
