Beborex brakes were also available with a wheel rolling on a flat, in
addition to the lever/slot arrangement depicted in your photos. I have both
versions and I can't tell much difference in operation on the road. You can
see the wheeled version of Beborex brakes on this Peugeot on Bikeville's
website: http://www.bikeville.com/

Can anybody provide more information on the history and design of the Beborex brakes?
