Re: [T3] Speaking of brake lines

While I appreciated that the longer a hose is the less water flow there will be
for a given pressure due to surface friction etc, I reckon the rate of flow
through a restricting nozzle will be different if the hole is smaller, and with
the pistons moving a mm, there's a significant fluid movement through a
restriction.  I can't see why they bother to specify the outlets to use for the
calipers and the ones for the brake-light switches if it makes no difference.

There are plenty of cases where we accept that VW engineeers probably know best
when it makes no safety difference; seems to me braking is one situation where
we should listen to them.  OTOH, partially seized calipers, non-original pads
and worn discs are very likely a greater source of brake imbalance that which
outlet you use for the pipes.
