Ya, I think the old Speed TV had a series in which Winfield was one of the featured drivers. Looking at the set up, it appears to use the brake system in which a master cyl is integrated into the steering wheel hub. Usually, this is used for hand-operated front brakes found on some TaG karts. I’d wonder if it had sufficient volume for a front + rear system, though I imagine it has enough for a rear-only system. The italian motors system uses an external master cyl and might have a higher volume piston.
