Uneven pad wear can be caused by badly worn discs ( rotors ) or caliper problems - such as a sticky piston. Since you've changed the discs, the calipers seem to be the next most likely candidate. Maybe a worn wheel bearing could affect this too but that would be readily identifiable. > While doing the brake job I also notice that the tires are wearing out on > the inside edges much more quickly than across the rest of the tread.

Wheel alignment can be knocked out quite easily - for example by 'kerbing' the car. Graham
