When you start your car, the last thing you want to deal with is a noise that you can't control or diagnose. If you notice that your car starts to make a squealing sound every time you brake, it might be time to investigate the issue.

These are some of the reasons why that noise might be happening and what you can do to fix the issue.

The Brake Pads Are Worn

One of the most common causes of squealing when braking is worn-out brake pads. This is an issue a mechanic can fix easily.

As your brake pads wear down, the metal backing plate can start to rub against the rotor, causing a high-pitched sound. This is a sign that you need to replace your brakes as soon as possible in order to avoid further damage to your car.

Brake pads require replacement every so often, so this is not a rare occurrence.

The Brakes Are Wet

Another potential cause of squealing when braking is wet brakes. This happens when moisture accumulates on the brake pads and rotors, causing them to stick together.

This issue is common after it has rained. You don't need to do anything about this. The brakes will dry on their own as you drive, and the squealing should stop.

The Brake Rotors Are Faulty

Another possible reason for a squealing noise when braking is faulty brake rotors. This issue can be caused by uneven wear or excessive heat from heavy braking.

If you notice any pulsing in the brakes or strange vibrations, it might be time to have the brake rotors inspected.

A mechanic can easily replace any faulty components that are causing the issue. This fix will include resurfacing or replacing the rotors completely.

The Brake Calipers Are Stuck

Another possible cause of squealing when you brake is stuck brake calipers. This happens when a part of the brake system fails to open or close properly, which can stop your brakes from working properly.

In this case, you will need to have the calipers inspected and repaired or replaced by a qualified mechanic. Calipers can be more expensive than other issues to replace.

Talk to a Mechanic About Squealing Brakes

No matter what is causing the squealing noise when you brake, it is important to get your car checked out as soon as possible to prevent any further damage and ensure that your car is safe to drive.
