Hi all,
after shearing off the seized bleed screw on my rear calliper during stripdown, I decided to buy another, when I looked around online I found there were not any listed for the MC18. My desperation led me to scour the auctions for callipers from other models, which eventually paid off when I discovered they are exactly the same as the CBR400 nc23 baby blade ones, and there were many available, well chuffed!
