I doubt if it will do that. However, Nevr-Seez and most other anti-sieze
compounds use oil or light grease as a carrier for the aluminum particles,
so should not be used in any application where contact with brake fluid
might occur. If some of it gets carried into the brake system, it will
cause the rubber parts to swell. Not good!
If you're using silicone brake fluid, just lube the bleeder threads and
brake line fittings with it. Or, regardless of your choice of fluids, use
brake cylinder assembly lube. You can get it in small bottles or tubes at
large auto supply stores. One bottle will last your lifetime (unless you
run a brake shop), and you can pass it down from generation to
generation of future BritCar-loving Walkers. :-)

Your choice of brake fluid has nothing to do with it. Regardless of the
fluid type, petroleum-based substances must NOT be allowed to get into the
hydraulic system.

Be careful to remove all traces of the grease before you disassemble those
fittings!

Even with silicone fluid, it's good practice to bleed brakes thoroughly at
least every two years to remove any water or water-contaminated fluid from
the system. An hour's work once every two years can make your hydraulic
system last a lot longer.
