Just received a replacement front disk brake caliper from my parts
guy... (lets not mention that he first supplied one for a non-vented
the box contains, in addition to the caliper, a pair of bolts for
caliper to bracket fixing, a pair of small rupper bellows for the
guide pins, and a small packet of silicone compound, type DOW CORNING
Where does that go? Bently manual (and Hayes Book) does not mention
it... is it for guide pin lubrication?
