screeching from rear brake fn2 type R

[obito86]

hi guys, recently got my first honda (FN2 type r) and am loving it, however when i drove today my rear right wheel started making a strange noise, it screeches when i apply the brakes and the noise sometimes stays afterwards when driving without braking. however if braking hard the noise does not happen, only after light braking. does anybody have any ideas what this could be? the car supposedly had a full service around 2k miles ago so surely a wearing brake pad would have been noted?
cheers
