Squeaky or grinding brakes? Here's what they mean and how to fix them

Brake noise is one of the most frustrating sounds a driver can experience. It’s not just annoying, but it can also signal a critical safety issue. This can compromise your vehicle's ability to stop effectively, putting you and others at risk.

If your brakes are making noise, it’s essential to have them inspected by a professional mechanic as soon as possible. MyMechanic, Malaysia’s No. 1 car service provider, is here to help.

How Your Brakes Work

Brakes are essential for bringing your car to a stop. Here's how they function:

Disc Brake System: Includes pads, rotors, and calipers. Common in most vehicles.
Drum Brake System: Includes shoes, drums, and wheel cylinders. Found in some vehicles.

Both systems rely on hydraulic pressure to slow down or stop your car effectively.

Common Brake Noises

Brake issues usually produce these noises:

Grinding
Squealing or squeaking
Clattering or rattling

Grinding

Grinding brakes require immediate attention. This often means the brake pads or shoes have worn out completely, leading to metal-on-metal contact.

Cause: Worn brake pads or shoes.
Solution: Replace pads or shoes and inspect the rotors or drums.

Squealing or Squeaking

Persistent squealing can indicate issues like low-quality pads or worn components.

Cause: Worn or low-quality brake pads, debris, or glazed rotors.
Solution: Replace pads, clean debris, and machine or replace rotors if needed.

Clattering or Rattling

This noise may point to warped rotors or missing hardware.

Cause: Warped rotors or loose components.
Solution: Replace or repair affected parts.

Why Brake Inspections Are Critical

Even if your brakes seem fine, they should be inspected at least once a year. Malaysia's driving conditions, such as heavy traffic and humid weather, can wear down braking systems faster.
