Q: Loud Noise when braking at high speed

Hi there. If the humming noise is a high pitched hum, or more of a consistent squeaking sound, it’s possible that it is caused by a build-up of brake dust on the brake rotors. In most cases, this is not a cause for concern, however, it could also indicate that your brake pads are low and about time for replacement. It’s always a good idea to have brake pads replaced before the wear indicators begin to touch the brake rotors, as this often results in damage to the rotor. I would recommend having a professional mobile mechanic come to your location and complete a brake system inspection to make sure you don’t have any damage to the brake system or to inspect the brake pads to determine if they need to be replaced; which is a service we can also complete for you at your location.
