I think that you can do some initial investigations yourself here.
Why not jack up the front right-hand side of the car, with the wheels turned to full left lock, and spin the RH wheel, checking for any problems. Then remove the wheel, and carefully examine the rotors, checking for signs of pitting (deep corrosion) on the surface. A slight touching of the pads on the rotor is OK, but nothing severe, which could indicate warping of the rotor.
Check also that your tire has not been rubbing against anything on full lock.
I also use a screwdriver to clean off the rust that always accumulates at the top edge of my rotors - the small area that is only just clear of the brake pads. This is often responsible for brake squealing and other strange noises.
If that side is OK, take a look at the left-hand front wheel.
