Found a few previous posts on this which suggest the problem is pad locating pins needing a clean up but not sure if this is the same noise they mention.
Had thousands of miles of trouble free use from the same pads and discs etc and never had this before. Seems to be from both sides almost alternatively in quick succession but hard to pinpoint location.
Braking performance is fine and it only happens within the final few millimetres of pedal travel mainly when coming to a stop.
Bled them and briefly checked them over and all seems fine but will strip down further tmrw.
What do you think?
