problem with 89 LX-I suspension and brakes
After driving for a while and only on highway my car starts shaking like crazy you can feel it in the floorboards.The only thing that usally helps it is if I hit the brakes real hard.Last summer my calipers froze to the rotors and it brought me to a sudden stop with lots of heat and smoke.I broke the bleeders on the calipers and drove it home once it cooled down.I took the wheels back off it an hour ago and noticed the rotors have about three or four cracks in them a piece.Could this be causing my vibration?
