Is that pads only or pads and discs?
At around 40K miles my brakes started making grinding noises - no warning lights although it was obvious the pads were near the end of life all round. I took it to a (non-Alfa) indie near my place of work and they replaced the front discs + pads front and rear. I was given a choice of OEM or pattern parts. I decided on OEM and it cost £600. I think they gave everything a good clean while they were about it and the brakes were (and still are) the best they've ever been.
If there any signs of disc wear I would replace them, especially at the front, otherwise you will just chew through the new pads in a very short time.
