I never mentioned corrosion in my post (see above) all I said was 'I understood that you should never use lock thread compound on any fixings that go into alloy threads'
...
But if you feel you need to use it on your brakes parts then that's fine.

Anyway as I said at the end of my post 'just saying trying to be helpful '
If you really want to make sure they don't come loose you have a welder.
And if thread locking compound has no impact why use it, it does have impact it causes threads to shear off in alloy.
Helpful is fine, when it is helpful, but not so fine when you don't know what you are talking about and the advice you end up giving is dangerously wrong. You understood Locktite and alloy threads had a problem. You understood wrong. Locktite does not cause threads to shear, overtightening causes threads to shear, and greasing threads before attempting to torque them is a great way to ensure they are overtightened. The only problem associated with alloy threads is galvanic corrosion, which is a potential risk when ever two dissimilar metals (alloy or otherwise) are in the presence of an electrolyte. Locktite is not an electrolyte, copper-grease can be and introduces another metal to the equation. As for the brake disc bolts, the Yamaha Fazer 1000 service manual, Section 4, page 15, "Brake disc bolt", torque to 18Nm, LOCTITE. 18Nm is less that half the torque used on the caliper bolts. A quarter of the torque for the front axle and just over 10% of the torque for the rear axle. It is NOT VERY TIGHT! That is why you use locktite to ensure they stay in place. If you do them up like a gorilla, you will fuck the heads, you will fuck the threads, you will probably fuck the mount holes, and you will have problems removing them.
If you don't know what copper grease is for, or how it works, you really should refrain from recommending it until you find out, and if you want to recommend something that seriously contradicts the service manual, you should a) know what the service manual actually says, and b) have a pretty bloody good reason for saying it is wrong!
