[Healeys] Goodridge Brake Lines - Warning

[Oudesluys]

At first glance stainless steel brake lines seem to be a good idea. 
However they are not. Technically they may be illegal in many countries 
as you cannot have a double ended flare. There may also be a problem 
with metal fatigue and last but not least, if you use copper washers to 
seal you may have electrolytic corrosion of either the stainless steel, 
or the zinc/cadmium on the steel parts. In most climates cadmium/zinc 
plated standard brake line are the best. In damp climates with salted 
roads consider Cunifer or another copper/nickel based pipe. However 
brake lines, whatever they are made from, need to be checked over every 
year, but we do that anyway, don4t we.
