Thanks for the advise Baggy, if i get time tomorrow i'll give that a try and see what happens.
Aaron - As for the new rear discs and pads, i've had the car just over 6 months now and noticed in the service history that both front and rear pads were replaced 4 months before i purchased the car, the rear o/s caliper was also seized at the time and was repaired also.
In your case though i'm surprised the noise isn't being made when cornering left also, as you've had both discs replaced they'll both require bedding in?
