I decided to tear down my Avet SX Raptor for the first time and found a significant amount of rust on the drag surface of the inner Brake Disc. I cleaned it up the best I could with a wire brush on my electric drill but some pitting in the disc remains. How critical is it that all pitting be removed or should I just order a new Brake Disc and be done with it?

Thank Avet for their "dry drag". If you want a smooth drag replace the plate and grease the CF drag disk so it does not happen again.
don't worry about the pitting. once cleaned up, you should be good!!!

I cleaned the rust out of the drag washer with CRC Brakleen and a toothbrush, then let the CF drag disk thoroughly dry. I then rubbed Cal's grease into the drag disc and wiped off any excess with a clean paper towel. It was almost as though all the grease was absorbed into the carbon fibre. Did I use enough grease?
To insure the pitting will not continue I,d rub more grease into the Carbon fiber and then rub off the excess on the surfave with a clean cotton rag. ... Like greasing the boat trailer bearings. Its good insurance.. ;)
You shouldn't be able to see the grease on the drag washer after rubbing it in and wiping it off. It makes the drag smoother and keeps water from getting in and causing the issue you had!
On reels I've repaired when this is found I sand with 400 grit followed by wet sanding with 1000 grit. I always grease their drags after that. Maximum Cal's grease applied and maximum amount I'd wiped off. Good to go!
