Kia Amanti - Sudden Brake Failure

[atari_400]

Hi there,

My wife was parking her 2005 Kia Amanti today and the brakes mysteriously failed.

She pressed the brake pedal but the car kept moving forward and eventually mounted the curb. She said it felt like it surged forward when the brake pedal was pressed. A witness saw what happened and said that the brake lights were illuminated.

I test drove the car afterwards and also took it to the dealership but so far cannot find anything wrong. No fluid leaks, pads are good etc.

One thing I did notice is that if you keep applying pressure to the brake pedal you can push it to the floor.

Can anybody suggest anything else I can check ?

Thanks.

Have the brake master cylinder checked for pressure drop and/or leaks. Most likely when foot was on brake pedal pressure dropped off allowing pedal to drop and your foot slightly touched the gas pedal.
