I wasm looking at a post on here or the lcgb site recently on this very subject. Some dealers have a shoe trimming tool for profiling new shoes. The DIY method is to file away the high spots with a rasp or similar using chalk to indicate high spots. Takes time but does work apperently. I need to do this myself, useless rear brake on lammy but fantastic front and exactly the opposite on my T5
Oh and beware if they have asbestos, you will need to take appropriate precautions i.e. get someone else to do it
