A couple days ago I posted an article about signs and symptoms of worn and torn rotors. And in that post I explained that many people need new rotors, and only find this bit of news out when they go in for brake problems. However, I negated posting anything on brakes. But I want to go into that here because brake pad replacements are a more common occurrence than rotor issues. Plus, braking is kind of a big deal in driving!
Brakes are designed to make a loud pitch squealing noise when a small attache device actually touches the rotor. Towards the end of the life of the brake pad, you will hear this noise, indicating that the problem is coming.
Brake pads, as they wear, will actually begin to vibrate the vehicle a little bit when applied to the rotor. This is usually a sign of problems, or worse yet, that the rotor is warped.
Any foreign or weird noise may also indicate a problem. If an object gets lodged in the brakes, it will make a noise when braking as well.
Should your brake pedal fall all the way down to the floor when depressed, it is usually caused by air in the brake lines. This is bad, as the car will probably not stop at first. If this happens, continue to pump the brake pedal, this will often help.
And if you ever find leaks, do not hesitate to get repair done immediately.
