Squealing or squeaking brakes
A high-pitched squeal when braking is often harmless vibration between pad and disc, but it can also be the built-in wear indicator telling you the pads are nearly worn out.
Can I keep driving? Safe to drive short-term, but have it checked to avoid failed emissions or worse fuel economy.
Common causes
Pad wear indicator
Many pads have a small metal tab that squeals against the disc when the pad is close to its minimum thickness.
Glazed pads or discs
Hard braking can glaze the surfaces, which then squeal.
Missing or worn anti-squeal parts
Shims, clips and lubricant on the pad backing plates damp vibration.
Morning moisture
A light rust film after rain or overnight squeals for the first few stops, then stops. This is normal.
Low-quality or very hard pads
Some performance or cheap pads are simply noisy.
What to check
- Check the pad thickness through the wheel or with the wheel off.
- Look for the metal wear indicator touching the disc.
- Check the discs for glazing or a deep lip.
