Noticed mushy, vibrating brakes. Took it to tire store and was advised the brake booster and vacuum pump are bad. I've had several close calls in parking lots, as the vehicle is slow to resond to the application of the brakes. The drivers seat is also loose. It moves from side to side as I go around corners. I'm afraid it will come off the rails or worse yet, not secure me in the event of an accident.
