Mayf,
     You read too much into my reply, there is no un published criteria that 
must be met and approved. If you have only front brakes you must apply for a 
waiver stating you accept the risks and the waiver must be signed by the 
head tech inspector.

Ok, with the information that a rule exists to prevent brakes only on
the front axle unless a set of unpublished criteria is met and the
design is approved, this is now officially a dead issue for  me. Hold
you emails please... I'll stick to the rule book... If  I decide to
change my break set up, it will be with a lever operated rear brake
system only.  I only use the brakes when speeds are way way down anyway...
