Ok I was in for a pleasant surprise when I got to the dealers, they thought there was only a dust seal and piston seal per pack but there is in fact two so only around £25
I am currently trying to get all the brake fluid out of the callipers. I have put a tube on the bleed valve and took the top of the reservoir and pumped the leaver which got most of it out but there is still a bit in the calliper that came part way down the tube them went back into the calliper and I won't come out if I pump the lever. What do i do to get that out? Or do I just take the calliper off with it in?
