does the noise occur under braking or cornering ?
thanks for the extra info
in that case this could be a fault with a wheel bearing or the new brakes binding slightly
the brakes are more likely so strip the calipers down, remove the pads and clean out all the pad grooves and location in the caliper, smear a thin layer of copper grease on the metal back of the pads where they touch the piston and where they rub in the tracks of the calliper also clean the calliper tracks of debris and dust before re-fitting the pads.
The copper grease won't melt under hi temps so DO NOT get it on the brake disc or friction face of the pads, it does however keep the brakes working smoothly and help reduce any squeal as it damps things out
you can also check for worn suspension joints by jacking the car up so the wheel is off the ground and shake the tyre from top to bottom and from side to side (with someone holding the steering wheel). There should be no play in either direction.
Any play in 1 direction will usually require a suspension joint to be replaced, if there’s play in both directions then the wheel bearing may be at fault
do you still need help?
