See parts 8 amnd 9 on here. I've bought them before, but changed to stainless 'P' clips. I can give you mine if you're desperate. https://www.fowlersparts.co.uk/part...cbr1000rrb/fr-brake-master-cylinder-cbr1000rr
Not desperate for them, just changing brake lines and noticed the one on right won't do the job with race setup. I'll get one ordered, cheers nigel
