Brakes Squealing or Grinding? What to Know

A squeal or grinding noise from the brakes usually means the pads are worn or something is caught between the pad and rotor. Grinding in particular means metal may be touching metal.

If you hear grinding, feel a soft or sinking brake pedal, or the car takes longer than usual to stop, stop driving and have it inspected or towed. These are safety issues.

Quick checks you can do safely

Notice when the noise happens: only when braking, or also when turning or going over bumps?
A high-pitched squeal often comes from the built-in wear indicator on worn pads.
Check that the brake fluid is between the MIN and MAX marks on the reservoir. Do not open the cap.

What's usually behind it

Worn brake pads or wear indicators
Worn, grooved, or warped rotors
Debris trapped between the pad and rotor
Low brake fluid or a fluid leak

QUESTIONS

Brakes Squealing or Grinding: common questions

Is a little squeal normal?

Sometimes, especially in the morning or after rain. A persistent squeal or any grinding should be checked.

Do I need new rotors with new pads?

Often, if the rotors are worn or grooved, since new pads wear faster against a worn rotor. We show you the measurements before recommending it.
