Sometimes disk-brakes will make a noise as they 'unload'. By that I mean the
movable parts in the caliper and even the suspension parts supporting the
road-wheel come under considerable tension as they take on the load of
pulling up the vehicle, then when that load is removed on brake release
evrything twangs back into its 'at rest' position...but in a modern car I
wouldn't expect this to produce a loud noise. Wear or looseness in any of
the suspension and caliper parts can produce this symptom.
I'd be checking everything is tight from the wheel lugs/nuts, caliper
mounting bolts, suspension mountingbolts and the strut tower for movement.
The design of the caliper can contribute some light noise such as a clapping
or tick noise from the pads as they load-up and downm but not a loud
If you have a helper, you can go thru a braking-unbraking cycle by gently
applying some engine power in Drive while the brakes are on,..then release
the brakes. The helper maybe able to see where the movement/noise is coming
Get the car inspected if this isbeyond you.
