I put a Empi disc brake kit on my trike. I mounted the calipers on the top. I am have great brakes. A whole lot better than the drums. I am well satisfied with that part but I get a noise when I use the brakes a certain way. I don't know exactly how to describe it. It is not a squeak. Sometime it makes it when I have my foot on the pedal and I am almost stopped. Has anyone else had trouble with the Empi kit. I know the rotors aren't perfectly true. Any suggestions?
