I have an 03 reg mondeo 2lt tdci. I had the front discs and pads replaced
dec 09 as they were worn and it sailed through it's mot at end of Dec 09
with no advisories. I have now noticed what I can only described as a
grating sound? This is present on braking but also intermittently when
driving along, as though the brakes are binding somehow (and this may sound
stupid but is when driving is is more pronounced when the car is driving
left round a bend!)

I want to take the car back to the same garage but don't know wnough about
cars and want to know if this is the front brakes, and if so why is this
problem occuring when the discs and pads have been replaced and if it is
something else why was it not picked up as an advisory in the mot?
