What causes a grabbing noise like after changing the front brake pads on a 2005 Dodge Grand Caravan?

It was making like a grabbing noise ( don%26#039;t know how to explain it) every time you stepped on the brakes. Replaced the front brake shoes (which was worn down and needed to be replaced) Took it for a test drive and now that noise is alot louder then what it was before. It is coming from the passenger front side. I noticed on that right side rotor passengers side it had some grooves in the rotor. Which means that the brakes been down to far. But anyway the new shoes should wear in where it shouldn%26#039;t make any noise but still does. Got over 50 miles on the new brake shoes. Would the wheel bearing be going out on that side? That is my only thought now.|||There has been a rash of bad pads on the market recently. Some pads emit a gas when heated up just a little. Essentially Fart ing out between the pads and rotors making a horrible groan at very low speeds.
