This is funny because my wife took her '03 Disco to the dealer and they said the rear brakes needed replacing. I told her not to let them do it and I'd do it. I inspected the brakes and it was the fronts that needed replacing. Oh well.....marginal service. Anyway, I replaced the pads and that worked for about 5K miles and then the infamous lights started tripping. I just decided to replace all rotors and pads with EBC and now couldn't be happier. The whole thing only took about 2 Hours because I had to swap the front Rotors as they are directional when drilled and slotted. My wife loves the braking and I feel better with her driving a safe car.

Have you actually pulled the tires and inspected the brake pads?
At 45K, if you aren't getting any brake vibration on hard stops, I would let the rotors go till the next brake job and just install pads as needed, making sure to bleed the brakes afterwards and use lots of sound deadening material on the back of your new brake pads.
Might want to contact Atlantic British, they carry a numnber of different pads as well as rotors.

Fair enough!
