These two problems with trees here in the UK have received quite a bit of publicity but has anyone heard of their being any problems with Sycamores?
In the last two years, our large previously healthy tree has started to die. Some bows have obviously died, while other parts of it hardly have any leaves. There are portions of the tree which are in full leaf but this season, well over half of it is has been affected in the way that I've described. There isn't any sign of damage to the bark at the base of the tree or anything like that.
it was here when we came in 1988 and it was a fair size then. I've no idea how long they're supposed to live for.
I'll try and get some pictures that illustrate whats going on.
they do shed limbs/die back/die sometimes ,this can be due to a variety of.
one fungi that seems fairly common shows as small red " bumpy dots "on the bark and can kill a limb or entire tree.
squizzers do like the bark and sap but they do leave obvious chewing evidence and if the "last of the mohican tails"got shot decades ago i suspect fungi.
it looks like a fairly elderly specimen ,perhaps a bit of surgery would prolong it's life , it might look a bit stumpy when the dead and ill bits get removed.
take the top (poorly looking bit)off imho and leave the bottom half to see if it survives (it might).
making it smaller will also reduce the load on the roots which might revive it a bit (and will certainly prevent the top popping down to the conservatory for a nice mulled cider during a storm ).
I don' t think there is anything worse than leaf miner affecting sycamore at the moment, although I think there might be some risks from the continent. Virtually every plant can get things like phytophra though, so check for any bleeding parts of the trunk. Is there any compaction round the roots, or has there been any change in the water table that you are aware of? All things that can affect mature trees, apart from the dreaded squirrels.

Is the tree particularly important to you? The easiest answer by far is to have it down.
I would not want a sick tree that big that close to my house: it only needs to drop a twig to go through the conservatory.
Found this. Not suggesting that is what you've got or not.

My neighbour down the road has paved his drive & a nice horse chestnut which has no illness whatsoever shows symptoms just like yours.
Purely down to water stress.
They transpire hundreds of gallons of water a day.
Half the roots on your tree aren't getting very much.
(IMHO).
