"PBS" stands for "Progressive Braking System" apparently.
It seems one pad was fixed and the cable caused the other pad to move inwards; presumably when it met the rim, that caused the whole calliper to rotate and press the fixed pad against the rim.
Can't think why they didn't catch on...

Never used them but apparently they're awful. Still, nice to see some originality.
