The brakes on your car are a critical safety component that must work correctly to keep you and others safe. But they do take a lot of pounding as they convert the energy from your moving vehicle into heat to slow or stop it. Over time that friction can cause them to make noise or even start to behave differently than usual. That’s why it is important to pay attention to any unusual brake sounds and not ignore them.
Some brake noises are simple and easy to fix, while others could indicate serious mechanical problems that need immediate attention. In this article we will discuss three common brake noises and what they might mean for your vehicle.
Squeaking Brakes
A squeal when you hit the brakes is often caused by a small metal tab on your brake pads that is revealed as the pad material wears down, giving you a warning before it is time to replace them. The squeaking is created when the metal rubs against the rotor as you slow down or stop your car. The squeaking may also be caused by moisture, dirt or other debris that is getting into the brake caliper, usually from the outside of the wheel. This can be easily solved by a quick inspection and applying some brake lubricant to the area.
Rust on the Rotor
Rust can build up on your rotor plate over time, especially if you park outside or in damp weather. When you apply the brakes, the rust scrapes against the metal of the rotor, creating a squeal that can last for several stops until it is cleaned off. Keeping your brakes lubricated and parking in a garage or covered can help prevent rust from building up on your rotor plates.
If the squeal is constant, or you notice your brake pedal sinking to the floor when you apply it, that’s a sign that the caliper isn’t properly seated on the rotor. This can be a dangerous issue, and should be addressed as soon as possible. The best way to avoid this problem is to have the caliper repositioned or replaced by a professional mechanic.
Grinding Noises
A grinding sound when you brake is usually a sign that the pads or shoes are completely worn out and are causing direct contact with the metal rotor or drum. This will create a loud grinding noise that should not be ignored, as it can lead to more expensive and dangerous repairs down the road.
In summary, any strange brake noises should be inspected by a professional as soon as possible to ensure your safety and that of other drivers on the road. If the brakes are not functioning properly, they can cause damage to other parts of your vehicle and put you in danger on the road.
