Yamaha banshee rear master cylinder rebuild kit works for the master cylinder.Or you can just buy a used master off e bay for the banshee.they fit the z.You just have to reuse the lower adjuster that attaches to the brake lever.I have ordered the individual caliper kits for honda's but not the tri-z yet.So I dont know if they are available.Most of the newer banshee master cylinders are bare aluminum,so polishing them is easier.I just did mine last night.took about an hour.
Here is where my long useless list of stuff nobody cares about should go...
