I bought a used track bike that was already setup. I was looking at the Brembo master that was already installed and it is the 16x18, which according to Brembo’s site, is used for single caliper brakes on stunt bikes, or rear handbrakes. Do I need to get rid of this master and purchase another unit? Or is it fine to use it as is? I haven’t had any issues with it yet.. It’s on a 2013 ZX6R. Thanks,
