How do I know if my brake lines need replacing?

Do you know when you last had them inspected? Brake lines start showing wear through visible corrosion or weeping fluid around the fittings - check under your car for wet spots near the wheels. More importantly, if your brake pedal feels spongy, goes down too far, or you notice your brakes aren't as responsive as they used to be, that's a sign the lines might be compromised. Get them checked by someone who can actually look at them rather than guessing, since a failed brake line is genuinely dangerous.

The spongy or soft brake pedal feeling is honestly one of the earliest warnings before you see visible rust or leaks, so pay attention to how it feels under your foot when you're braking. If the pedal goes down too far or feels less responsive than usual, there's probably air in the lines or a micro-leak starting.
