Of Doctors and Chips

I've always been accused of being a hypochondriac when it comes to cars.You know the sort of thing,the slightest noise heralded impending doom;a squeak was imminent suspension failure,a whine most likely meant the transmission and final drive were due to pack in,or if I was lucky just a wheel-bearing on the way out.Sooo, bearing this in mind you can imagine the old hypochondria kicking in good and strong when we got to Cornwall and they'd just re-surfaced the road in some town or other;you know the kind of thing,layer of tar and sprinkle liberally with stone chippings and let the windscreen replacement boys have a second birthday.Previous to entering said town our CX had performed flawlessly,no nasty noises so I'd had a stress-free drive. Stopping at a junction and then moving off again produced a disturbing grinding noise.After imagining all sorts of dire problems,I reversed the car a couple of feet and tried again.Nothing, not a sound, back to normal.The CX has rear disc brakes with a shield behind each disc and of course a stone chip had got itself wedged between disc and shield,making the grinding noise.Reversing pushed the stone back out.I decided perhaps I'd turn a deaf ear to all but the worst sounds in the future.
