Just an update..
Had the calipers referbed and due to NZ not having many Cossie parts here, they used a ford / volvo rubber kit and replaced one of the pistons with a Mazda RX 8 one.. I know that Mazda mixed it up with Fiesta a few years ago but i wouldn't have though these parts would mix.
I should have took a pic as the piston has a different face. It has two undents so the pads sit in to it though. They are back on now..
Thanks again for the help Fella's.
