I would start by turning the rotors. By the time the brakes wear out, there has been enough heat on the rotors to warp them. Then start looking at tie rods and wheel bearings. The noise you are hearing when you hit a bump could be a couple of things. My 90' is making the same noise and it is the exhaust pipe hitting the transmission crossmember. It could also be one or both of the shocks are loose and are moving around.
