I was getting some grinding when slowing to a stop on my front brakes, so I pulled the tires to check the pads. The rotors were GM OEM original to the car, and this was probably the 3rd set of pads. It had a pad-slap about 2 summers ago but only 10k miles or so since then, so I was pretty sure the pads were ok, and they were. However, since I had it all apart, I decided to go ahead and just replace the rotors and pads. $75 or so later and I had Wearever rotors and Wearever Silver pads installed. This was the first time I had done brakes by myself, and the first time Id ever done rotors. Everything went back together easy. Braking was good, smooth, quiet. This was about 2 months ago. About a month ago, I had to make somewhat of a hard brake. Since then, the front brakes are grinding again. Seems like they are getting worse. When I come to a slowing stop at a light or stop sign, both sides sound like they have rust on the rotors. I drive the car daily so its not actually rust. Could it be the cheap Silver pads causing the problem? Could it be the wheel bearings? I hear those go bad on this car often, but Ive never had a problem in 13 years that im aware of.
