Wrong. That's the primary reason SS lines are used in a lot of applications
besides/including our vans. As soon as I put them on a 914-6 I used to
autocross and short course race, the brakes performed incomparably
better because the front brake lines (especially) did not expand under
the hot brake fluid temps generated by that kind of driving. I also put
them on a Westy automatic I had and again, significant improvement
because the rubber brake lines were not expanding under repeated
hard braking. Rubber brake lines expand over time and brakes fade
and become less effective  because of it. Mushy pedal ... you can
feel the line expanding. As soon as I replaced the fronts with SS braided
lines that completely disappeared.
