We are talking about what could make the GTS brake system fluid more prone
to air/water contamination than other brake systems. Yes everyone knows
brake fluid is hydroscopic and needs to be replaced periodically, whether
you have rubber or steel hoses or whatever, but most listers believe it
needs to be done at least every 6-12 months on the GTS to avoid an expensive
HU failure, certainly a situation I've not heard of with any other brake
system. And I agree or at least think it's a wise precaution.
Peter Piazza was suggesting difference in maintenance/storage might be the
reason the GTS HUs were failing while in his opinion the FJ HU's were not. I
disagreed and said that even if the HU's were identical the rest of the
brake system was not, which could be where the problem lies. Or as I said it
may have just been one bad batch of HUs. I don't believe FJ owners on
average maintain or store their bikes any better than GTS owners, in fact I
would be surprised if the opposite wasn't true.
Cheers Joe.

Actually,
It is known. Rubber brake lines allow moisture to be attracted by the brake
fluid through the lines. It is known as hydroscopicity. This is exactly why
there are maintenance intervals on changing the brake fluid.
