I Just bought the brake parts, put the wheel in the otherwise complete frame.
and only made 1 brazing jig, a piece of flatbar,
drilled a bunch of holes in it, the last one a slot to adjust width by less than a whole between holes.
holes sized for rhe 6mm bolt that holds the brake on. so the bosses are parallel .
My Ca. '75. DIY frameset. Mafac Cantilevers . in my case,
Where I put the brake boss on the frame was the adjustment.
now the pads can be moved in the slot, that might be handy since tensioning the chain
moves the rim away from the brake pad, then you have to readjust the brake pad.
BMX a V brake is not going to get kicked , neither are U brakes.
that is why they use either 1 or the other
U brake frame pivot is above the rim, V brake Below.
