A good thought, Roland. Although the original user of one firm seems to
have had no problem. Besides, not sure about the synthetic in the brakes
yet. Using it in the clutch to see what happens. Easier to replace.
Most sleevers use brass, which has an even higher thermal expansion, but
probably not as high as the aluminum, so maybe it keeps outer contact
better. These are made with a friction/press fit, so some expansion still
leaves compression between the sleeves and the cylinder.
