Why Does My Car Squeak When I Brake?

Hearing a squeaking or squealing noise every time you press the brake pedal can be annoying, but it can also be your car's way of telling you something needs attention. While not every brake noise means there's a serious problem, it's always worth getting unusual or persistent noises checked.

One of the most common causes is worn brake pads. Brake pads contain friction material that gradually wears down every time you brake. Once this material becomes thin, some pads are designed to produce a squealing sound to warn you that replacement may be needed.

Your brake discs can also cause unwanted noises. Over time, discs can become worn, scored or develop corrosion on their surface. This can prevent the brake pads from making smooth contact with the disc, resulting in squeaking, grinding or vibration when braking.

Another possible cause is contamination. Dirt, brake dust, road debris or other contaminants can sometimes get between the brake pad and disc. After a vehicle has been parked in wet weather, light surface rust can also develop on the discs. A little noise for the first few applications of the brakes can be normal, but persistent squeaking should be investigated.

So, when should you be concerned?

If the noise continues, becomes louder, turns into a grinding sound, or is accompanied by reduced braking performance, vibration, pulling to one side or a warning light, it's important to have your brakes inspected as soon as possible.

Your braking system is one of the most important safety features on your vehicle, so ignoring the warning signs isn't worth the risk.
