I recently started to notice a rattle coming from the rear, particularly when driving over surfaces like those "concrete" roads found in housing estates ...... the ones that are left very rough on top.
I removed the near side rear wheel to investigate. Did some pushing and shoving around to see if I could locate the source. The only thing I found was that the outer brake pad seems to be rattling a little in the caliper, apparently through normal wear. It's nowhere near worn down to the minimum 1.0mm level, though it is closer to 1.0mm than it is to the standard 10.5mm.
Could that be enough to cause a rattle noticable from inside the car ? I thought the anti-rattle spring was supposed to stop that kind of thing happening, but I'm thinking that maybe the pad is worn to the point where the spring is now ineffective.
