Symptoms drivers describe
- High-pitched squeal at low speed
- Squeaking that fades once the brakes warm up
- Squeal only in the wet or first thing in the morning
- Constant squeak that gets worse as pads wear
Possible causes
- Brake dust or light surface rust on the discs
- Glazed or hardened pad material
- Wear indicators contacting the disc as pads get low
- Worn or unevenly worn pads and discs
- Missing or dry anti-squeal shims and slider grease
What you can do
- Note whether it happens cold, wet or under braking only
- Have the pads measured rather than guessing at thickness
- Do not ignore a squeal that has turned into a grinding noise
How we check it in the workshop
We remove the wheels, measure pad and disc thickness, check for uneven wear and inspect the caliper sliders and hardware before advising.
Is it safe to keep driving?
Often not urgent on its own, but worth checking soon — squeaks can turn into metal-to-metal grinding, which is far more expensive.
