Hi,guys need help with problem brakes, when braking there is a loud grinding noise as if the abs is on this only happens when I've slowed down at junctions etc and happens as I am just about to stop which I can feel through the pedal also, there are no abs/tc lights lit and this fault happened once before last year on and off for a couple of weeks then stopped before I could get it checked but yesterday it seems to have come back with a vengance grinding noise nearly every time I'm braking and just as the car is about to stop.
