Squealing or Squeaking Brakes
A high-pitched noise every time you brake.
What's happening
A sharp squeal or squeak as soon as the brake pads touch the rim or rotor — usually more annoying than dangerous, but worth checking.
Likely causes
- •Contaminated pads (oil, road grime or chain lube)
- •Glazed pad surface from overheating
- •Slightly misaligned caliper or brake arm
What to do
It's usually safe to keep riding, but have the pads and alignment checked — contaminated pads brake less effectively than they sound.
