It is common for drivers to ignore minor brake noise or irregularities for too long. Eventually you may end up in a situation where your car requires a repair that is much more expensive than it would have been otherwise. Even worse, the car is unable to stop in an emergency situation, causing an accident that could have been avoided.
Brake rattle is a common concern for drivers. Most often brake rattle happens when you let up off the pedal. Usually it sounds like the rattle made when shaking a can of spray paint. The most common cause of this noise are the pads, because it is caused by heat expansion, especially if they were installed without anti-rattle shims. Keep in mind that this rattle should not be consistent and it should never happen while you have your foot on the brake pedal. Under either of those conditions, you should have your brakes checked. It could be the sign of a more serious problem.
Grinding noises you hear
When your brakes are making a loud grinding sound when you press on the pedal, this is almost always caused by contact of the rotor disc with part of the caliper. This is usually because of extreme wear to the brake pads or rotors. Another reason that brakes may make a grinding sound is when a foreign object (such as a stone) gets lodged somewhere in the caliper. When this happens, the brakes will usually make a consistent grinding or screeching sound when the vehicle is in motion.
Overheating of the brakes
Brake fade is a condition where the brakes have become overheated, and they don’t function normally as a result. Brake fade is most common in situations when brakes are being used more. This includes going down a long hill. When you experience brake fade, you will notice an issue. The pedal will require extra effort to yield the same stopping power. If you notice this issue, bring it in. Noticing an issue with your brakes requires immediate attention.
