Rattling or clicking sounds When the brakes make a rattling or clicking noise, this is an indication that your brake pads need replacing. The rattling and clicking is caused by the vibration of loose components which damages the brake pad.
Why does my car make a clicking noise when I slow down?
A clicking sound whilst driving slow can also be a sign of loose brake pads. If the brake pad is not secured properly to the caliper, it moves around when applied at slower speeds and makes a clicking sound upon braking. The fix for this would likely be a brake pad replacement.
Is brake pad rattle dangerous?
Many brake pads look similar in design and it is easy to get supplied the wrong parts. Using the wrong parts that are undersize can be dangerous as the brake rattle if excessive could mean the pads moving in the caliper and becoming even jammed and not operating properly.
