Brake Drum Wheel Cylinder problems of the 2003 Hyundai Elantra

My concern with my 2003 Elantra is with the safety of rear braking system on the car. On oct 23, 2003 I had the service performed for the recall 31b03r1 brake campaign 061. At 10,834 miles. On oct 7, 2007 I had regular scheduled maintenance performed complete brake system flush at 45,072 miles. On July 8, 2008 both rear wheel cylinders were leaking an had to be replaced as well as the complete brake system flush again. At 51887 miles. On March 13, 2010 both rear wheel cylinders were found again to be leaking and had to be replaced at 64,638 miles. I have had my car serviced at regular 3,000 mile intervals with all required maintenance done at my dealership. My concern is the safety of the brake system on this car,leaking wheel cylinders that need to be replaced at 13,000 mile intervals seems like a serious safety issue to me.

The brakes on my 2003 Hyundai Elantra began grinding at only 39k miles. I contacted the dealership and was told brakes were not covered by my extended warranty. I took the car to midas because of the lifetime warranty and the brakes were not failing due to normal wear and tear. The front pads had a metal plate on the outside which had come lose and was cutting into the hub. The mechanic said this was a defect in the brake pads that occurred when they got hot and the adhesive came loose. During the inspection, they also discovered that the cylinders on the rear brakes were leaking. I ended up with over $600 in brake repairs.

: the contact stated prior to the brakes failing, an odor of brake fluid was noticed. After the vehicle was towed to the service dealer, the problem was identified as leakage of the rear wheel cylinders, which were replaced. The vehicle was taken to an out of state service dealer for scheduled service and the contact was informed the brakes needed adjustment. When the vehicle was taken to the service dealer, the contact was informed the rear brake cylinders were leaking again, after only 8118 miles and 13 months time. The manufacturer was not alerted.

The contact owns a 2003 Hyundai Elantra. Beginning on December 17, 2005 the brake pedal extended to the floor when depressed. The failure occurred intermittently. When the vehicle was inspected by the manager at the dealer, the contact was informed that the brakes should not do that, but there was nothing wrong. The vehicle was towed a month and a half after it was purchased because the contact smelled brake fluid and the brake pedal was extending to the floor. The dealer initially believed that the brake cylinder failed. Currently, the front brakes are scraping and still extending to the floor. On October 1, 2007 and October 2, 2007, the vehicle was thoroughly inspected by the dealer and they found no failures. The powertrain was unknown. The current mileage was 38,000 and failure mileage was 21,344.
