Odd, mine was diagnosed on one day, pads delivered and repaired the next. It was the exhaust bracket that took 10 days to come (it's in now having that fitted).
The new pads, so far, have cured the noise though mine did occur after about 1000 miles or so, guess I need to do the same and fully bed in before pronouncing a success. Nice not to have the grinding noise at present though!
Mine did it cold or at temp, odd yours is only one extreme?
