New Rotors/Pads, worrying grind...

I replaced the brakes last weekend using DBA T2 rotors on front and rear, and Bendix Ultimate pads, i took it out after and bed them in as per Bendix recommendations, let them cool down for a while then went for a bit of a cruise, all went well.

Driving to work this week i noticed a sound yesterday morning while in slow traffic, when i'm just rolling along or going under 20km/h and apply the brakes gently i get a very worrying grind from the front left wheel but goes away when i apply more heavy braking, everything feels fine and works well but i never had this noise before, nothing feels loose and i made sure i removed what minimal rust there was so the router would mount flat, i used to have a constant squeak from the from left rotor before hand which went away when braking, it disappeared after the replacement but now a faint squeak has just started (which is also constant until i brake)...

Does anyone know if i should be looking at anything in particular that could cause this? is it common and may eventually go away?

I'm a little stressed as it doesn't sound like something small...

Check the dust shields aren't touching the back of the rotor.

Could be a dead wheel bearing.

I took a short recording of the high pitched sound if it helps identify what it is at all...

I took my wheel off and checked everything over again before i went for a drive just now and couldn't recreate the grinding noise again, will see how i go in the morning on my way to work.

Whichever ones are making noise.
