I've had alot of trouble with my rear brakes so I'm a tad paranoid about them and always have a quick look at them to see if anything there looks different to normal. Today when I looked I noticed the clip arrowed below on a pic I found was hanging different on my driver side caliper. So what I did was poked at it to see if it would sit properly again resulting in it falling out! So my question is what is this clip actually for and does it need putting back in??
Thanks
