here is the brake mod that the guys where doing to there bikes.
using a small hold down clamp.
some where one clamp and two clamps.
last one I was told it was a factory holder that seam to be missing on most super bronc's
also note they use a small spring over the cable. this also had a mod brake light fab up on the end of the brake unit.
What a fantastic day it was for a ride among fiends . Seeing so many of these Super Broncs still in original paint and condition speaks to how well these bikes where designed and built . If I remember right this was our 5th get together and certainly the most attended .
Great pictures Brian
