TW,
            Possibly a film of grease has impregnated the brush and caused the high resistance.
Maybe a bit of a rub with an abrasive on the working end may fix it.

Love it when someone gets a result.

Has the old brush been carved from some sort of resistor?

I had a Mag that somebody carved a pickup brush out of plastic?? I should have suggested another brush!

 Yeah, but if you had it repaired, how can you be sure it's the same brush that it had?? Maybe the repair shop got some bits 'mixed'..?

Good onya TW, great to see it's sorted.
Many moons ago I replaced the earth brush (same problem, couldn't stop it) with a carbon center of a C size battery. It lasted for about 10 years.
