I've been tasked by swmbo with fixing a couple of curtain tracks that are pulling from the wall. One is a standard white curtain rail fixed in multiple points, the other is a pole with only two fixings, one at each end.
Both are pulling from a brick wall which is plastered over, and neither fixing can take a larger screw.
How can I successfully repair the holes such that I can use the same sized screws in holes which are strong enough not to pull out again?
car body filler after raking out the loose stuff. Do not use rawlplugs:
the body filler is drillable and screwable. And paintable. For perfect
repair leave the body filler a little below the surface then skim over.
The New Left are the people they warned you about.

10mm dowel, hammer drill, and use the dowel as a rawl plug. or buy bigger screws. All my internal walls are block and these are the two methods I now use. Car body filler would probably pull out of my walls, maybe not with yours.
If your inner walls are white solar blocks, then you don't need to use
a hammer drill, or even conventional masonary drill bits. Ordinary
HSS drill bits without hammer action should give a nice clean hole.
Then use the correct type of plug for this type of block. Ordinary
tapered 'rawl' plugs aren't really suitable.

Yep, unless you know what the actual construction is one solution will
not suit all conditions.
My 1905 property is plaster over brick but its not a modern plaster. In
places its very sandy and when drilling the edges of the hole just
crumble away. It's also very thick in places (2.5cm+) so relatively a
long way before hitting brick. A car body filler repair would just pull
out as the weakest point would be the old plaster to repair bond.

I'm a keen user, but I don't think it would have been any help in the
lime/horsehair plaster in my last victorian house, unless going back
deep into the stonework (on the front) or brickwork (middle and back). I
also had this on lath and plaster partitions and ceilings.
As earlier poster said, the optimum solution depends on the construction
and also the type of load to be supported. The soak-in polyester resin
is one of the best solutions when stabilisation is needed (but not
particularly cheap or easy).
Galvanising does not have to be continuous to work though. At the
extreme, ships have a few blocks of zinc attached to protect the whole
ship. It is a sacrificial anode, not a protective coating.

I use ordinary filler for that, works a treat. Polyfilla type stuff, not lightweight. Just needs a few days to dry out before refixing. You can either fill & redrill or push wallplugs in & let it set.
Why is the screw pulling out? Is the plug also pulling out?
Is the hole for the wall plug too large for the plug?
Is the brick/plaster crumbling as you drill?
When originally fitting were the fully into the hole with the end flush
with the wall? If not you may have just been relying on the screw alone
to stop any movement rather than the curtain rail fixing being clamped
firmly to the wall to prevent some movement.
If the hole is marginally too large, and a clean hole with parallel
sides, then another type/brand of wall plug may fit tighter in the hole
and/or have thicker wall so that when the screw is inserted it grips the
side of the hole a lot tighter. I've found that the red type plugs that
are often supplied with the item are of very poor quality and I always
replace from my stock of Fischer branded grey nylon plugs. (I also have
some similar/identical ones that came from Aldi/Lidl at one time)
Again, if the hole is marginally too large then insert one or more
wooden cocktail sticks down the hole before banging in the plug,
trimming off excess wood from the stick afterwards. You can substitute
match sticks (cocktail sticks tend to be thinner and a harder wood)
If the hole is way too large and possiblly crumbling at the plaster
surface make the hole much larger, paint the inside of the hole with
50:50 PVA:water and allow to dry, apply a second layer of PVA/water and
while still damp completely fill the hole with filler. Make sure the
filler gets to the back of the hole by pushing it in with the back of
the drill bit. after it is dry re-drill the hole to the correct size for
the wall plug. Don't re-use the old wall plugs.
Also, it seems odd they are pulling from the wall, are the curtains
particularly heavy? Is there somebody in the household who yanks them
because they are sticking perhaps. This is easy to fix with some cleaning
and lubrication if its a properly designed rail.
Maybe you need rawl bolts, done right you can swing on those once they are
