I have a 2012 Ford Escape that is a front wheel drive, which recently started to make a grinding sound when braking. The brakes are brand new, less than 10,000km. My brakes used to make a horrible grinding noise and then I replaced the front pads and rotors. The grinding stopped but has started to come back when I brake at slow speeds (under 20km/h), it’s more frequent after extended periods of driving. Everyone is at a loss to the noise. Any ideas?
