My car was at Don Fields' shop awhile back and he did some AWESOME work on it. But one of the things he did was change my break pads to Mintex Blue pads, and now they are starting to squeal a lot. I'd rather not take the car all the way back to Don's place just for this, so I'm going to try to fix it myself. Does anyone have any ideas what it could be? I've never done anything with this car but I want to start learning how to work on it. The brakes work really good, they just squeal when I'm stopping at a light, etc. and it's starting to get embarrassing.
