Removing rusted, very stuck brake rotors

It is absolutely amazing how it works on brakes in areas with lots of snow. It reduces or eliminates corrosion like nothing else I've tried over the decades. No type of anti-seize even comes close.

Honda's "Moly 77" is a much-less-expensive copy of the true Molykote M77, but I am assured that it works identically to Molykote's version. Honda's part number in Canada is 08798-9010CH. Might be different in the US.

Where do you use it on the brake system?

M77: Any place where movement occurs. On the pad ears where they slide on the stainless steel shims in particular, although I like to remove the shims and apply paste onto the caliper, as that is a major source of rust and thus (eventual) binding. I don't use it on the pad shims (anti-noise shims) as I have not had reason to do so (doesn't make noise dry), nor on caliper slide pins.

I have a handful of nuts-bolts-washers in my tool box for exactly this reason. Interesting thing...
In the past month and a half, I did brakes on my Wife's 09 Kia Sorento, my stepdaughter's Jeep Liberty and my 09 Suburban. The Jeep and the Kia both fought me all the way. I had to pop the rotors off using the bolt trick.
I could not remember the last time I swapped rotors on my truck so I was expecting the worst. The rotors slid off the suburban with nothing more than my fingers.
I guess GM does a better job with whatever coatings they use on their hubs. It was a nice surprise to get a break.

acetylene torch between the lugs on the rotor hat till you hear it pop and the rotors pop right off.

a Dab of whatever is in the grease gun hits the hub contact points. I dont bother with anything except brake grease for the slides

Anyplace where there is metal-to-metal sliding action.

Sand off all rust first.

Eric from south main auto uses an air hammer. He lives in New York and doesn't have a problem at all. Buzzes them loose in about 10 seconds at most.

Between the bolt/nut technique and the Molykote 77 referral, this post gets five stars!
Thank you

I always remove the brake discs shortly after I purchase a new vehicle and burnish anti-seize into the disc/hub interface. Never have a problem with removing the discs, not after twelve years.
