Delta and AX lunacy.
As someone else mentioned they don't like the rain. Perhaps Kool pads would help but Delta pads are unique to the design
Funnily enough the Dura Ace AX (the direct competitor of Campy's Delta gruupo) also don't like the rain.
Legend has it the two manufacturers got together and agreed they'd both go broke if the continued with so much extra machining of parts and both groupsets were discontinued.
Sunbeam did a very similar brake caliper in the 1930s! They don't like the rain needless to say, nor the dry either but hey-ho.
