I have a zx6r J2 track bike and on a slow speed when I use the brakes it feels as if there only working intermittently and on a high speed the front shudders a lot. Brake pads are new, brake fluid is fine with no air and they Galfer discs have done around 4000 miles in the last 4 years. Do you think the discs cause this problem? I was thinking about the front fork bearings.
Thanks very much
