Thanks again John Went to a motor factors today with a digital photo of both sides. I've ordered what I hope is the right kit. It was £8.99 so a big difference from the £40 quoted from Citroen main dealer. I'm hoping that it just clips on over the top and that I don't need to remove the pads to get it in. It's been a lot of trouble for a little rattle. It doesn't affect the braking but that rattle is very annoying!
