Brake rotors

Just need to grow two more arms , to go with my second tasmanian head  ,,

Hello, I removed my rotors to powder coat the wheels. No amount of penetrating oil will loosen the locking compound on the screws. You need to use heat to break the bond, then use an impact that you hit with a hammer, and the correct metric allen socket. If you do that , you won't mess up any screws.

So ........ the proper allen key, some heat, and impact to break the bond of the threadlock and any corrosion that has seized the rotor to the rim.... is the order here eh..?

When I was working at it I thought of heat, but balked at it thinking that I might warp the rotor...
Has anyone ruined a rotor by using heat (like a propane torch?) to help remove the bolts?

Er... heat is what they are designed to take.... What do you think happens when you are clipping along and then grab a hand full of break lever? Your momentum is converted from inertia/kinetic energy to heat. They can take it...

Yes, the proper tool and some form of impact.

If, as I recall, you are removing the rotors to paint your wheels, and will be refitting them, the heat will ruin the paint on the discs.

Also, the amount of heat required to be effective is more than I would like to apply to rotors I was refitting.

I have found propane ineffective for loosening bolts, it doesn't burn hot enough.

The thread lock keeps the corrosion at bay so you only have to deal with that and it IS only thread lock after all.

I recently removed some after 100,000k's that had never been off. They're not THAT tight.

Propane works fine for me to break threadlocker's grip on things.  It doesn't take a quick wave of the flame, it takes a good bit of time, but it works well enough and isn't hot enough to really destroy things.
