I'm having problems with my rear discs and pads on my polo. I've gone through 2 different sets in the past year and I just can't understand why!? It only seems to be the drivers side that is affected. I first took my car to a garage in eastham who had them changed for me, only for the problem to occur again a few months later, so I took it to another garage and bouth the discs and pads myself for them to change. It starts of as like a faint squeeking noise under low acceleration, but when I'm coming to a stop, it makes a sort of grinding noise. I've just had a quick look at my discs when I got to work, and the right onw looks scored, but as far as I can see, the pad is still in there. The left disc though looks completely fine. Does anyone know what this may be before I start throwing more and more money at it?
