Taapping sound that goes away when i press the brakes

[LoPe in HD]

Basically when i cruise i hear a constant tapping coming from my rear left tire that stops tapping as soon as the brakes are slightly pressed. What is this noise, does anyone know? couldit be the caliper being loose? or the the god speed coilover?

wheel bearing is possible. rotor warped, sticky caliper.

Could be dirt or something like that with your brake pads.

Probably wheel bearing. Are you sure it's a tapping noise or is it a noise you hear when a lifted truck with big tires drives by?
