One problem related to brake drum shoes/linings has been reported for the 1999 Kia Motor Sephia. The most recently reported issues are listed below.
Had to go to hospital for surgery. Car wouldn't move the brakes were locked. Couldn't go forward or backwards. The back wheels would just slide. The brakes are still in good shape half the pad is left and when we got home from my surgery husband went out to check the problem and here the brakes just fell apart in pieces. We had to buy new brakes and put them on I can send the old brakes in they are the original brakes that where on the car when we bought it. I fear this could happen while someone is driving and could case a bad accident.
