1. Soft brake pedal: When you press the brake pedal, it feels spongy or goes all the way to the floor with little resistance. This is a classic sign of air in the brake lines.
2. Brake fading: The brakes don't seem to work as well as they used to, and they get worse the more you use them. This can also be a sign of air in the system, as the air bubbles compress under pressure and reduce the amount of fluid that can reach the brake calipers.
3. Uneven braking: The brakes pull to one side when you apply them. This can be caused by air in one of the brake lines, which prevents the caliper on that side from getting enough fluid.
4. Leaking brake fluid: If you see brake fluid leaking from the brake lines or calipers, this could also be a sign of air in the system. The air bubbles can cause the fluid to leak out past the seals.
5. Grinding or squealing brakes: These noises can also be a sign of air in the brake lines. The air bubbles can cause the brake pads to vibrate against the rotors, creating a grinding or squealing sound.
If you suspect that you have air in your brake lines, it's important to have the brake system inspected and repaired by a qualified mechanic as soon as possible. Air in the brake lines can be dangerous, as it can reduce the effectiveness of the brakes and increase the risk of an accident.
