If your brakes are making a squealing noise, it’s usually a sign of worn brake pads, glazed rotors, or a lack of lubrication on brake components. While some squealing can be harmless (like light surface rust after rain), persistent or loud squealing often means your brakes need inspection and repair to maintain safe stopping power.

What does it mean if your brakes squeal?

Squealing occurs when the brake pad material, wear indicators, or uneven rotor surfaces create high-pitched vibrations during braking. It’s an early warning that your braking system may need attention.

Common causes of squealing brakes

• Worn-out brake pads with exposed wear indicators
• Glazed or uneven brake rotors
• Lack of lubrication on brake pad backing plates or slides
• Cheap or poor-quality brake pads
• Dust, rust, or debris between the pad and rotor

Why do you need to fix this problem quickly?

While some brake squeal is minor, persistent squealing may indicate thin pads or rotor issues. Ignoring it can lead to metal-on-metal contact, longer stopping distances, and costly rotor or caliper damage.

How do you know when to get it checked?

You should book an inspection if:

• The squealing noise occurs every time you brake
• The sound gets louder or is accompanied by grinding
• Your brake performance feels reduced
• You see a brake warning light on the dashboard

What happens during an assessment?

A mechanic will:

1. Inspect the brake pads for wear
2. Check the condition of the rotors
3. Inspect calipers, slides, and hardware
4. Clean away dust, rust, or debris
5. Advise on brake pad or rotor replacement if required

How much does it cost to fix?

Brake pad replacement typically costs $200–$400 per axle. If rotors also need machining or replacement, costs may rise to $400–$800 depending on the vehicle.

Is it unsafe to drive with squealing brakes?

Yes. While not always immediately dangerous, squealing often signals worn pads that reduce stopping power. Driving without repair risks further damage and longer stopping distances, which compromises safety.
