I have a problem with my vehicle and I really do not know what is the problem. I do not know if I need brake lines. I got my brakes and rotors check and I was told that they are in good condition. But as I drive I have to push down to get my vehicle to stop, when I do finally stop I feel as in my brake pedal goes down as it pumps down by itself while I am at a light or stop sign. I checked my brake fluid and it is good.
