Squeal— a common brake noise which frequently means that a metal wear indicator in the brake pad has been exposed, showing it is time to have the brake pads replaced. It can also mean a brake is dragging, which may indicate a need for maintenance.
Clunk — a clunk on braking usually means that one or more of the brake components is loose. Requires immediate attention.
Grinding — A rough grinding noise indicates metal-to-metal contact, which usually means the brake pad has been worn through. Again, have your brakes checked immediately. Alternatively, if the vehicle has not been driven for some time, it could be caused by rust on the brake discs, which may be removed over time during normal driving. This may also be accompanied by brake judder.
