If I set up an Electrum wallet from a brain wallet seed, do a transaction where a change address is created, then delete the wallet file, will the change addresses always be recreated from seed?

I'm concerned after reading this:

If Electrum acts as I have described above, can someone explain what is different about Multibit that they would have lost their change address private key? Was a completely new wallet created just for the change address?

That guy lost coins because he went the manual paper wallet route. You are relying on a full fledged offline wallet so you won't face this problem if you are careful.

You need two things:

- The seed

- A copy of electrum to recreate the wallet from seed.

Now as far as new change addresses go you might need to give electrum a little hint that it should generate those addresses. It can always do that as long as you have the seed. It just needs a little push in the right direction:
