Hi, I have a 98 explorer that I thought the brake pads were gone, so I had them replaced yesterday. It had squealed while I was braking... While I was driving it last night on an interstate, the front end shook when I was about 70mph, even slowing down, it still shook, but not as bad. Now this morning, after driving it home from work, it still squeals, actually a grinding/squealing type noise happens when I brake. Any clue what this could be? I am a single mom, and would like some advice before I take it to a shop, and get taken (again!) Thanks so much!
