hey, i have a 97 854 base model. my problem is that sometimes when i brake, a heavy vibration shudders through the car. its not everytime i brake, but it happens maybe every other time i brake. it vibrates very heavily, through the frame, and i cant locate where its coming from. At first i thought the engine mounts had gone, so they were replaced. did nothing. i replaced the brake rotors in the front. no change. the cv boot on the front drivers side is shot and leaked oil(?). I think that maybe the oil got into the brake pads and could be the cause of the vibrations, but thats only a theory. has anyone had this problem or have any others sugestions? im at a loss. thanks in advanced.
