I have a 1995 Chrysler Cirrus. Recently, my ABS has been acting a little funny. I will go and push the brake pedal to stop the car and it goes down fine and the car does stop. However, after applying pressure to the vehicle for a couple seconds, the brake pedal goes down even farther and the car makes some sort of weird sound (a zzzzzzzzzzz sound) and osmetimes the lights dime. I'm still unsure on why this would happen. The car still brakes and stops fine, its just this problem. I'm looking to fix it so I can sell it. Any suggestions?
