Squealing or squeaking noise when braking

Needs attention soon

brakes squeal · high-pitched noise when stopping

Symptom description

A high-pitched squeal, usually most noticeable on the first brake application of the day or at low speed.

Common causes

  • Built-in metal wear indicator touching the rotor (designed to squeal on purpose as an early warning)
  • Glazed or hardened brake pads from overheating
  • Dust, moisture or light surface rust on the rotor after sitting overnight
  • Cheap or low-quality aftermarket pads

What to check

If the squeal only happens on the very first stop of the day and goes away, it is often just surface rust and not urgent. If it is constant, have the pad thickness checked.

Can you keep driving?

Usually fine short-term, but treat it as a reminder to get the pads inspected soon - a squeal today can become a grind in a few weeks.
