The ISCI people know what they are doing----the hydro brake kit is beautifully done, professional in every way, and the instructions, written by Robert, a guy who knows how to tell you "How To," and it functions like part of the original Spyder package. This brake made the Spyder a completely different riding pleasure. I can hit the hand brake, and it will do what you want---slow down, come up quick, and stop on a dime. Whst I really like is the stopping power it has when you hit both the hand and foot brake at the same time---supper bike stopping. The two brakes work both separately and in conjunction with each other. The ISCI, hydro hand brake is an assit to the foot brake---two hydro systems functioning together---the guys who engineered this system are really smart---and ISCI will do very well indeed. Check them out and look at all the Spyder items they have developed....can't say enough about them!! Being old, , slow, and particularly careful with all my moves when down when sliding around on the floor, it took me eight hours to install it---about an hour to bleed the system by hand----What a wonderful addition----Thanks Billy Joe Jones and Robert
