My main concern when one of these discussions comes up is that someone will buy a bunch of mismatched parts and end up with a system that's actually dangerous, instead of being "safer" than what was there originally. A minor miscalculation where the diameter or pedal stroke is concerned could result in brakes that either require too long a pedal stroke to get all the brakes applied, or a very short stroke that requires a massive amount of pedal effort to get the vehicle stopped. Either situation could get exciting, or worse, particularly if there's a failure of half the system. I seriously doubt that many, if any people on this site actually understand how the system becomes redundant in case of the failure they're so afraid of. Do they realize that the brake pedal will go to within a couple of inches of the floor before they get any one-axle braking at all, and pumping the pedal won't help?
