I found that the plastic brake line works perfectly well with very
little stretch. I'm using Nylo-Seal NSR 1/8" OD, .026" wall stuff so
the internal volume is as low as possible and the hoop and
longitudinal stresses are reasonable. I originally expected that the
small internal cross-section would make the flow rate low enough that
the brakes would be slow to apply and slow to release, but that has
not been the case. It seems that disk brakes operate with such little
displacement that even .004in^2 of cross-section on a 4-foot tube
provides adequate flow.

Thanks, Bob K.
