I've put other posts up about such but had a Photobucket clear out so had to find some others.
Although I changed the original disc for an EBC and put Carbon Lorrain pads in it wasn't until I altered the adjustment(ratio) on the radial front brake that I got the feel,could probably have got the same with stock disc and pads but I doubt if the disc would have lasted very long.
So yea its a radial front brake that you need.
