A bleed kit is a bleed kit, all it is a syringe/ sqeeze bottle to push brake fluid through the lines. The only diffrence in bleed kits are the adapters to connect the hose from the syringe/ bottle to the calliper, and possible the brake fluid. I guess you could just buy one for avids and then try to buy adapters for the formulas, and possibly diffrent brake fluid.
I suggest you just buy your own, it will be much easier.
