If your brakes are squealing or squeaking, there could be several reasons for the noise. Some causes are minor, but others may require immediate attention.
- Squealing brakes are often caused by worn brake pads. Brake pads often have a metal indicator that squeaks when they need replacing.
- Moisture or surface rust on the rotors, especially after rain, can also cause a temporary squeak that usually goes away after a few uses.
- Dust or debris trapped between the pads and rotors can create noise and may need to be cleaned off.
- Hard braking or braking downhill can cause the brake pads to overheat and glaze, which leads to squeaking.
- Some brands of higher performance sintered brake pads can naturally make noise due to the material they’re made from, especially if cold.
- Drum brakes might squeal if they aren’t properly lubricated and maintained
If the squeaking noise continues or turns into a grinding sound, it's important to consult a mechanic right away to avoid further damage. Persistent noise could signal a serious problem with your brakes and be a safety issue.
